Need To Pass A Hair Drug Test In Your Future?
You’ve come to the right place.
On this site, you’ll find the latest information about how to pass a hair follicle drug test, get your questions answered, and learn about the four proven ways to beat it – including which THC detox shampoos work best, how long you need to abstain – and more.
If you have a question about your situation, I’m more than happy to help. Just leave a comment at the bottom of any page.
Alright, let’s get straight to it:
Four Proven Ways To Beat a Hair Drug Test
If you’ve been using drugs frequently for more than a few days recently and have a hair drug test coming up soon, then there are only four proven ways to pass a hair drug test, as follows:
- Abstain for 110+ Days: The most proven way to beat a hair test is also the simplest. Just stop using at least 110 days before your next hair test.
- Shave It All Off: Don’t have 110 days before your test? Then you can try shaving your head and your body. But be warned: most test labs are onto this trick. If they can’t get a 90-day sample of hair, then they may fail you.
- Do-It-Yourself Detox: You can try stripping THC and other drug traces from your hair using a proven home hair cleaning regimen and/or detox shampoo. The Macujo and JerryG methods are two proven at-home hair detox regimens that lots of people swear by.
- Use Detox Products That Work: Only a select few hair detox shampoos can clean traces of alcohol and drugs out of your hair. But skip the drinks and pills – they won’t help you on a hair drug test.
Learn more about these four methods.

Hair Drug Tests Are Now the Norm
In the U.S., the hair drug test is gaining favor over older and more frequently used urine and blood tests for three reasons:
- Hair tests detect a much longer history of drug use: Hair stores a longer history of drug use than either urine or blood, which are limited to days for most drug types.
- Hair tests are harder to cheat: there are no privacy issues with removing a hair sample from a person’s head, so the sample can be taken in full view.
- Older tests are losing effectiveness: urine testing has become less reliable due to the proliferation of cheat products like synthetic urine and powders.
Occupational, Health, and Safety magazine recently recommended that H.R. departments use it over other methods.
In response, the market for home remedies and cheat products has boomed. Today, there are dozens of companies claiming they can help you pass a hair drug test with flying colors.
But can they?
Why I Built This Site
A few months ago, a good friend asked me to check the internet to see if there was any way to beat an upcoming hair test he was facing. We were in a restaurant, so I did what most people do – I Googled it on my phone.
The search results frustrated me. Most of the sites were unreadable, old forum posts, or filled with cheesy bylines and popups. NONE of them worked on my phone (see example below).
I’m an app developer, so this irked me. Don’t these people understand their audience (young, mobile)??
So, I took it upon myself to collect the most reliable facts and information I could find and get it into a site that anyone can read on their mobile phone.
To get smart, I interviewed friends that have used some of the home remedies, detox products, and test kits I found; I visited dozens of forums online; and, I spent a LOT of time researching the subject both on and off the web.
I learned there is compelling evidence that some products and cleaning methods improve your chances of passing a hair drug test – even if you’ve recently smoked pot, snorted cocaine, or taken narcotics. I also learned which products and methods work the best, based on feedback from real people who used them.
There are three groups of people who might find this site useful: drug users, employers, and health professionals. Each has a stake in the hair drug test.
Let’s start by discussing HOW hair drug tests work (not too complicated), then move into the various methods people are using to get around them today.
How The Hair Drug Test Works
The reason a hair follicle test works are simple: your hair needs blood to grow, and it gets that blood via the root of the hair follicle.
When you use drugs, traces of the drug are deposited directly from your bloodstream into and onto the hair shaft, via the hair follicle. Either the drug itself is deposited, or your body may react to a drug by producing metabolites, which are then deposited onto and into your hair.
As your hair grows over time, the chemicals that are deposited onto your hair store a record of your drug use, sort of like the rings of a tree record the changing of the seasons.
What Happens During the Test
When you arrive at the test location, a small sample of hair will be cut from the top or back of your scalp right at the skin line and placed into a sealed container.
A sample length of about 1.5 inches is typically taken because human hair grows about 1-2 inches every 90 days, and the period most commonly sampled is 90 days.
The sample is then sent to a lab to be tested for trace chemicals. Turnaround time on the hair follicle test is typically short, less than three days.
Which Drugs Are Detected By A Hair Drug Test?
The following chart shows which drugs are detectable by hair drug tests – and how far back in time drug use can be detected for each method.
As you can see, pretty much every drug stays in your hair, once it’s there.
Detection Times for Alcohol and Other Drugs
|Drug Type||Cutoff Level||Detection|
|Marijuana||50 ng/mL||90 days|
|Cocaine||300 ng/mL||90 days|
|Amphetamines||1000 ng/mL||90 days|
|Opiates||2000 ng/mL||90 days|
|PCP||25 ng/mL||90 days|
|MDMA||500 ng/mL||90 days|
|Benzodiazepines||300 ng/mL||90 days|
|Barbiturates||300 ng/mL||90 days|
|Codeine||100 ng/mL||90 days|
|LSD||0.5 ng/mL||90 days|
|Nicotine||200 ng/mL||90 days|
While some drugs will naturally degrade over time, THC traces tend to remain in your hair until you cut it.
NOTE: Most employers do not test for the following drugs:
- Hallucinogens (LSD, mushrooms, mescaline, peyote)
- Anabolic Steroids
- Hydrocodone (Oxycodone, Vicodin)
The hair follicle drug test was originally designed to detect heavy long-term drug users, not occasional pot smokers. For short-term testing, employers and labs still use urine and blood tests. That said, a hair test may detect an infrequent user.
A hair test can detect drug use for up to 12 prior months, but accurate results are typically limited to the past 90 days. In contrast, urine and blood tests cannot test for use further back than a few days. This is why a lot of employers prefer the hair follicle test.
Interestingly, because hair grows at a steady pace, a hair drug test can also tell an employer exactly when someone took drugs and when they stopped. Most tests don’t report the timeline, but take this fact into account when answering questions, after the test.
How Long Does It Take for Drugs To Get Into My Hair?
For head hair, it takes 5-7 days for tainted hair to be available for sampling because it takes that long for hair to grow from the root to above the scalp line.
From that point forward, drug traces will remain in your hair until you either cut it or strip it out with chemicals.
Hair Samples From Other Parts of Your Body
If your head hair is too short for the lab to sample 90 days, then the test station may choose to sample hair from other parts of your body.
In general, body hair grows more slowly than the hair on your head. The table below explains the drug test limitations of each source of the hair.
|Source||Limitations of Sample||Detection|
||1 cm=1 mo.
up to 1 year
|Pubic Region|| Alcohol Testing only:
|Leg|| Alcohol Testing only:
Learn more about how long THC remains detectable in your body and hair.
How Accurate is a Hair Follicle Drug Test?
The hair drug test is just as accurate as a blood or urine test, with the added advantage of detecting a much longer history of use.
Most drug test companies and labs claim 99% accuracy for all of their tests.
Which kinda makes you wonder: how the heck can anyone beat a test if it works 99% of the time?
The short answer, of course, is that just as with urine tests, hair drug tests are NOT 99% accurate in the real world.
People find ways around them. Drug tests have flaws.
Drug testing accuracy has been declining for many years.
Hair Drug Test Kits & Labs
It’s helpful to know which labs and tests are used most often by employers, and therefore are likely the most accurate.
For example, Psychedemics is widely considered the best hair testing company in the business, so if your test is handled by them, then you’ll need to bring out the big guns.
Also, keep in mind that you can also order a test to make sure you or your loved one tests clean.
Hairconfirm and Psychemedics are the leaders in at-home hair drug test kits. These kits are rated four stars or better on leading retail drug sites.

Four Proven Ways To Beat a Hair Drug Test
OK, so this is where the controversy begins.
I’ll start with the proverbial caveat: there is no single method, detox kit, or detox product that can guarantee you’ll pass a hair drug test. None.
That said, there are a few methods, products, and services that can give you a fighting chance.
All of these methods work by reducing or eliminating the residual drug footprint in your hair.
Some of the detox product manufacturers back their claims with up to 200% money-back guarantees, so apparently they are quite comfortable making them.
Let’s walk through each type of solution, starting with the simplest.
1. Abstain for 110+ Days
Yeah, I know what you’re thinking – duh.
But, honestly, if you are worried about getting or keeping a great job or you risk losing your child over a hair drug test, then your best bet is to just stop using, at least 110 days before your next hair test.
Why 110 days?
Well, if you smoke weed moderately or heavily, it takes up to 10 days for drug traces to drop in your blood, plus another 100 days to grow 1.5″ of clean hair through your scalp – enough to be sampled for a standard hair test (which looks back 90 days).
If your hair test is testing for drug use even further back, then you’ll need to grow longer hair – and abstain even longer.
Of course, not everyone gets 110 days advance notice of a hair drug test. We wish!
If this is your situation, don’t fret – you have three more options (keep reading)…
2. Shave It All Off
When hair tests came onto the scene in the mid-2000s, it was obvious to everyone that the most effective way to beat a hair drug test is also the simplest: about five days before your test, just stop using drugs and shave your entire body. Any hair sample that grows after that point will be clean because it takes about seven days for new hair to make it up to the scalp/skin line.
Maybe a little too simple, it turns out. There are a couple of fatal flaws with this approach.
First of all, many employers will automatically fail you if you walk into the test center with your head looking like a bowling ball. Think about it: you’ll have to explain why you shaved every hair off your body less than a week before your “hair” drug test.
Second, most employers are onto this simple hack, so it’s not advised. If they can’t get the hair from your body or head, then they will almost certainly test you using a urine or blood test, which will detect more recent drug use.
3. Do-It-Yourself Detox
Some regular drug users swear by two deep hair cleaning methods that you can do yourself at home using over-the-counter products.
The two most popular home cleaning methods are the Growman/Macujo and Jerry G methods.
Both methods remove traces of THC metabolite from your hair using chemicals.
The Jerry/Macujo method uses the old formula of Aloe Rid shampoo, salicylic acid, and vinegar, while the Jerry G method uses bleach.
There’s a lot of debate over whether these two methods work that well.
Most doctors and drug test companies say they don’t.
Hundreds of happy people say they do.
In many cases, people supplement a home remedy with special detox shampoos and/or detox body flushes, THC detox pills, and detox drinks.
But I haven’t seen any compelling evidence that supplements and drinks will help you pass a hair drug test. They are designed to help you pass a urine test, after all.
4. Use Detox Products That Work
Purchasing a detox shampoo to rid your hair of drug traces before the test is the easiest path, so a lot of people choose this route.
The problem is, there are lots of shampoos claiming they will eliminate all traces of drug use from a person’s hair follicles.
Most products can’t do it.
Let’s take a look at a few I found that seems to work.
Stripping chemicals out of your hair with a special cleansing shampoo is a popular solution, but be warned: only a few hair detox shampoos work as claimed. Most fail because they can’t get into the hair shaft itself, which is where many drug traces live.
As is true with any powerful over-the-counter remedy, the stuff that works costs more. So pay attention to the price. From what I can see, anything that costs less than $20 probably doesn’t work as claimed.
Old Style Aloe Toxin Rid Shampoo (Aloe Rid old formula) gets rave reviews and is by far the most frequently-recommended shampoo by people who’ve beaten the test. NOTE: Only the old formula works, and the original manufacturer no longer sells it.
TestClear still sells the old formula. TestClear bought up a lot of the remaining stock of Aloe Rid when the old formula was discontinued, so that’s why I recommend buying from them. But they are in short supply, and it isn’t cheap.WARNING: Be careful when shopping online. Scams are popular with this in-demand shampoo. People have paid for the old formula but received the new formula instead (WHICH DOES NOT WORK). Check the 1-star reviews on Amazon to see what I mean.
Here are the five best-rated and most frequently mentioned detox shampoos for passing a hair drug test. Aloe Rid (old formula) is by far the most recommended.

Hair Drug Tests: Myth and Facts
Here are some of the most common myths regarding hair drug tests we’ve seen flying around and the facts.
Myth: I’ll be safe if I shave off all my hair.
Fact: No, you won’t. Labs are used to such tricks.
We’ve touched a bit on this above. Shaving your head looks like a dead simple solution, but it likely won’t work. If the lab doesn’t automatically fail you, they’ll take a hair sample from your body.
This could actually be worse for you since it’s likely that body hair can show drug use further back than the 90-day drug use history head hair offers.
Myth: Any shampoo will clean the drugs off my hair.
Fact: You need special shampoos to strip the drug metabolites off your hair.
Ordinary shampoos are not nearly strong enough to remove traces of THC or other drugs from your hair. You’ll need a special shampoo that’s formulated specifically for hair drug detox.
But be careful which detox shampoo you choose. Many brands, especially the cheaper ones, make big but untrue claims about the effectiveness of their shampoos.
See our reviews of the best detox shampoos above, including Aloe Toxin Rid (old formula), Zydot, and Clear Choice, among others.
An effective detox shampoo will cost you more, but it’s worth it when it’s a job on the line.
Myth: Hair drug tests are used for only a few drugs
Fact: This was true a few years ago, but it no longer is.
More and more drugs can now be tested using a hair sample. Here are some of the drugs that can be detected using a hair follicle drug test.
- Benzodiazepines (Xanax)
- Buprenorphine (Suboxone)
- Zolpidem (Ambien)
- Synthetic Marijuana
- Amphetamines and methamphetamines
- Opiates (heroin, codeine, and morphine)
- Expanded Opiates (hydrocodone, oxycodone)
Myth: Labs cannot use pubic hair for a drug test.
Fact: This is true for some labs, but not all, so we wouldn’t recommend betting your career on a lab’s testing policies.
As we have discussed, shaving your head doesn’t save you from a positive drug test. The lab can take body hair, usually from the armpit, chest, face, or legs.
What if you shave off all those areas as well? Surely, they won’t pluck a hair from down there, right?
Some labs, as a matter of policy, won’t use pubic hair for drug testing. But some do. If you plan to shave as a way of beating a hair drug test (which we don’t recommend), you’d better shave everything from head to toe, as you can’t be sure the lab won’t take anybody hair they can use.
However, experts recommend against using pubic hair in a drug test because of potential contamination from urine. Urine contamination can actually increase the concentration of some drugs.
Hair Drug Test Cutoff Levels
Even if you have used a certain drug, you may be lucky and pass a hair drug test if the drug levels in your hair are below the cutoff.
The lab doesn’t automatically call a positive test if you have any traces of drugs in your hair. There has to be enough of them.
The cutoff level (expressed in picograms per milligram) varies for different types of drugs. Here are the common cutoff levels in a standard 5-panel hair drug test.
- Amphetamines, including methamphetamine, amphetamine, and ecstasy – 300 pg/mg for the screen (initial) test. The same cutoff also applies to the confirmatory test.
- THC – 1 pg/mg for the screen test and 0.10 pg/mg for the confirmatory test.
- Opiates including heroin, oxycodone, and morphine – 200 pg/mg for both the initial and confirmatory tests.
- Cocaine – 500 pg/mg for both the initial and confirmatory tests.
- PCP – 300 pg/mg for both the initial and confirmatory tests.
Frequently Asked Questions
What are the best DIY methods to pass a hair follicle drug test?
The two DIY hair detox techniques that seem to work for most people are the Macujo method and the Jerry G method. They are tough on hair, but they give you the best chance of passing your test.
We’ve not seen any other DIY method that’s successful enough for us to recommend.
How far back does a hair follicle test detect drug use?
A hair follicle drug test checks for drug use up to 90 days back. Hair can show drug use much further back than that. However, labs only use 1.5″ of hair from the root, which shows a 90-day drug use history.
How to read a hair follicle drug test result?
You’ll get your test results in 24-72 hours. A negative test result arrives sooner, while a positive result takes longer because of the second confirmatory test.
Your test results will display the screening and confirmation cut off levels. It’ll show the levels of different drugs detected in your hair.
If the detected levels are above the cutoff, that’s a positive test. If the level of drugs detected is below the cutoff, that’s a negative test.
Can a hair test detect one-time use?
It is unlikely that a hair drug test will be positive if you use a drug just once. Most drugs require repeated use for enough metabolites to be deposited in the hair.
However, if you took a large number of drugs during that one time, enough metabolites may have entered your hair to get a positive test result.
How much does a hair drug test cost?
A hair drug test costs between $50 and hundreds of dollars depending on several factors.
A home hair drug test kit will be cheaper than a lab test. For a lab test, the cost depends on the test panel. A panel that tests for more drugs will cost you more.
Note that if a potential or current employer requests a drug test, you usually don’t have to pay anything. The employer covers the costs of the test.
Can I use lice treatment to pass a hair follicle drug test?
You may have heard about some stoners using lice treatment to pass a hair drug test. However, we have not seen any evidence that lice treatment works. We recommend sticking to proven detox shampoos and DIY hair detox methods.
Can I use a hair relaxer to pass a hair drug test?
Hair relaxers contain chemical compounds that strip some of the drugs from your hair. One study showed a significant decrease in drug levels in hair that had been treated with a relaxer.
So, yes, you can use a hair relaxer to pass a hair drug test. To be safe, we recommend combining it with a good quality detox shampoo.

Thank you for putting this info out! Hate to see a one time user get labeled an abuser over a stupid hair test
October 24, 2014 @ 7:17 pm
Thanks Bill. You nailed the biggest problem with the hair test: a single use, months ago, can get you fired.
May 17, 2017 @ 3:15 pm
Been clean for almost a year, smoked 3 hits of a joint a month and a half ago and have a folicle test. I havent done anything at all prior or since that incident…am i going to pass?
May 18, 2017 @ 3:16 pm
Yes, my bet is you will pass.
August 5, 2017 @ 6:59 pm
So I smoked weed in a bowl for the first time on July 12th. Would I be able to pass a hair follicle test sooner than 90 days
August 6, 2017 @ 10:08 pm
Yes, as long as you don’t use any more, until then 😉
April 21, 2018 @ 4:48 am
Just found out I have to test next week. Which only gives me 4 days to pass the hair test. I smoke about half a G a day split with my husband.. I have stopped smoking and am using the macujo method (w old nexus) including a baking soda wash before the vinegar step to open the folicals.. If I do this twice a day for the 4 days and top it off with ultra clean the day of what do you think my chances are? Also I have dark curly hair
April 23, 2018 @ 11:10 pm
I don’t give odds here (no one can do that precisely).
But I can tell you that you are doing everything I know that you should do, to pass.
Wishing you the best of luck.
June 6, 2018 @ 1:57 pm
I have been clean since January and hit the pipe one time will I pass? I have a hair follicle test today
June 6, 2018 @ 8:15 pm
Yes, you should be just fine. One time use after that many months clean isn’t enough to fail.
August 2, 2018 @ 8:51 pm
karen Mcginnis did you pass. I have a test very soon wanting to onow if you passed and what did you do??
February 9, 2018 @ 6:46 am

August 24, 2017 @ 6:58 pm
I smoked 2 grams with a friend early march this year. I have a follicle test tomorrow…do you think I will pass?
August 27, 2017 @ 9:35 pm
Yes, I think you will pass. Good luck!
September 16, 2017 @ 2:42 pm

February 11, 2020 @ 9:23 am
So if u been clean for over a year and u have juat about a shot or 2 and are due for a test about 20 days later would u pass
February 13, 2020 @ 10:42 pm
Derek – yes, you would probably pass if that’s all you’ve done in a year+
February 13, 2018 @ 5:02 am
Okay so I need help I have a hair follicle test for a job I hit a bowl 2 times on New Years and then I took two hits of crack at the beginning of December I’ve been clean ever since that but in August I was heavily smoking crack and quit and was four months sober am I going to pass my test?
February 16, 2018 @ 11:18 pm
You will probably pass… 2 uses of each drug in the past 120+ days isn’t likely to fail you.
March 3, 2018 @ 9:03 am
I have been clean of everything for 2 years and yesterday took 2 hits of a joint. I will have a test in the next week, do I need to do anything special at all or do you think I will be good?
March 4, 2018 @ 9:34 pm
No, you don’t need to do anything special. Good luck on your test.
May 14, 2018 @ 11:15 pm
I ate 4 edibles about two weeks ago and I have a hair test at the end of the week, do you think ill pass?
May 15, 2018 @ 9:07 pm
Yes, I think you will pass.
October 20, 2018 @ 2:36 am
I have been clean for almost a year and smoked 2 hits of some pretty good weed about 2 weeks ago. I am going to have a hair test sometime in the next month. Am I screwed?
October 22, 2018 @ 7:07 pm
No, you’re not screwed – you should pass with no problem.
November 20, 2019 @ 12:15 am
I smoked the last couple years like 4-5 times a week sometimes more. If I stop smoking right now I should be ok in 90 days? It doesn’t continue to grow out of your hair until it is completely out of your system?
November 22, 2019 @ 6:21 pm
You will need more than 90 days for the reason you noted: for heavy users it will take 10+ days for traces of THC-COOH (the THC metabolite that hair tests look for) to drop below the legal limit in your blood.
From that point forward, new hair growth will be clean. But it takes about a week for new clean hair to grow through your scalp line (to be tested).
So, to be completely safe, you need to give yourself 110-120 days since your last use.
April 8, 2015 @ 12:18 pm
Do the two home remedies growman and Jerry G are they only good for the THC metabolites or does the remedies work on other drugs also?
April 8, 2015 @ 11:26 pm
Great question. The only strong proof I’ve seen is for THC, which tends to be the hardest drug to detox from your body.
March 4, 2016 @ 2:40 am
I just want to share my story:
I had a hair follicle test that I needed to do for personal reasons. The drugs I were concerned about were ALOT of xanax, a few lines of coke on two separate occasions, and a few adderall also done on maybe three occassions. So I would consider myself “borderline” for failing (mainly because benzo was not going to be on the 5 panel). I have dark brown hair, kinda thick, that hit right below my breasts. The two drugs I was concerned about were used about 1 1/2 months ago. The night before my test, I took some scissors and cut my hair to my collar bone (so there wasn’t so much to work with.) I dunked my head in warmed up apple cider vinegar and put a cap on. Every 20 minutes or so I re-soaked my hair when it started to dry out. I did this for about 1 1/2 hours and then fell asleep (lol) for about 4 hours. I woke up and re-soaked my hair and rubbed in Clearasil face wash with 2% salicylic acid. Rubbed this into my scalp and left on for another hour. Took a shower and rinsed it out with regular tide. Added a dab of conditioner because my hair was like a rug. Was done for the night and went to bed. Next morning, I took blue flash lightening powder and 30 volume developer from Sally’s and bleached my entire hair. I could only stand to leave this shit on my hair for 40 minutes because my scalp was ON FIRE!!! Literally tears, rocking back in for crying. I jumped in the shower and rinsed it out. I washed it out with tide again. I blew dried my hair and then got back in the shower and washed my hair with Omni from the head shop. Used half the bottle and shaped my hair up and scrubbed my roots for 20 minutes. Rinsed it out and repeated. I put a bit of conditioner in just so I could brush it. Brushed it out with a new brush and blowner dried it out. Then I dyed my hair back to my natural color. This hurt almost worse than the bleach. Cried like a baby for 40 minutes. Had to rinse it out in almost cold water because my scalp hurt soooooooooo bad. Had a little of the Omni wash left in the bottle so washed with that again. Just a normal wash. Conditioned it this time pretty well, blow dryed, styled, and sprayed with hair products in an attempt to mask the smell of dye. Went that day, took hair follicle test. It was at CRG and the lady cut right at scalp in the dead center of the back of my head. She actually cut so close I later found out she cut my scalp and I was bleeding! Just got my results and I passed! Wanted to share my story to help others in need! This website gave me so much great advice. Thanks!!!

I have a hair follicle test in two days for pre employment. I consumed cocaine 6months ago. So I decided to take a personal hair follicle test at a center. I got the test results and did not pass. My hair is 18 inches long, I’m scheduled to get a hair cut tomorrow and wanted to know if cutting 14 inches is enough to pass this test. Please advice!!!!

September 30, 2017 @ 4:40 pm
Hi guys! I just recently had to take a hair test for a job that can lead me into my engineering career. On my 100th day clean I was called in to take the test. I was a pretty heavy smoker but in the last month I switched back to mid weed since I know the the content is lower. During the week before I took a shit ton of biotin and let a clarifying shampoo sit on my scalp for 30 minutes a night. When I went into my drug test she cut my hair a half inch off my scalp! I’m terrified I’m going to fail, it’s been three days and no word yet, what do you think my results will be?! Halp.
September 22, 2018 @ 3:22 am
March 28, 2018 @ 10:22 pm
Sort of late on this but I had a hair drug test on March 23rd 2018. The last time I had used adderall was November 9th-November13th! I just got the all clear from the company I will be working for that my background check cleared, meaning my drug test cleared! It is past the 100+ day minimum.
Also a little about me: my hair grows very quickly, possibly more than the average .5 inches every month. Also did not use anything for the past 90 days. I also was very lucky to have a woman who cut my hair at the root. (I know she did because I felt the scissors exactly at my scalp). This was also a quest diagnostics test.
February 5, 2015 @ 1:34 am
I need some help. I quit smoking marijuana SIX months ago.. My first hair follicle was only TWO months after I stopped smoking and I failed.. So I had to take another one a month later and failed.. Now I have to take my last one the 11th of this month and I’m freaking. I should have passed the second time because it was 3 months but I didn’t and I fail my life will be ruined.. I’m not sure why I am failing..
February 5, 2015 @ 1:35 am
Can you fail from being around smokers!? It was the same level 1. Something both times and still failed! I haven’t done anything but I have really long hair and when she cut my hair she sent the full length off which was about half way down my back.
February 5, 2015 @ 12:26 pm
I don’t really know. The test labs say that, no, you cannot fail a test for THC due to exposure to second-hand smoke.
I’m not sure I completely trust them, but they’re firm on this.
March 20, 2015 @ 3:15 pm
I’ve read that if a person is around any toxins in the air (Marijuana smoke, for example) 48 hours prior to testing that the toxins from the smoke will stay in your hair due to exposure thru the air. Not 100% sure if claims are accurate, but something to think about.
April 4, 2016 @ 1:00 pm
I just failed a test and I have not smoked in over 30yrs. My brother smokes and I go visit him often and that’s the only place I am exposed to weed. So I would say YES and I missed out on a good job.
February 5, 2015 @ 12:15 pm
There are 2 things that can cause this kind of trouble:
1. The speed at which YOUR hair grows (vs. the average): hair on a human’s head grows at a rate of 1″ to 2″ every 90 days, or 1.5″ on average. Some people grow hair slower and others grow faster. For slow-growers, it can take more than 4 months for to grow a clean 1.5″ from their scalp.
2. Hair sample length: The other issue you may be experiencing is that the test sample taken was longer than 1.5″. It happens, but the lab typically won’t do that unless you employer specifically requested it (and paid for it).
If you think you’re a slow-grower or that your employer might have asked for >90 days of test visibility, then I would definitely clean your hair using the Macujo or JerryG method. Just to be safe.
Best of luck!
July 6, 2017 @ 9:38 pm
I did cocaine on monday have to do a hair follicle on Tuesday please help wut can i do
July 7, 2017 @ 4:34 pm
If that’s all you’ve done, then DON’T worry! a hair test cannot pick up on drug use just one day ago. It takes at least 5-7 days to show up in your hair.
If you’ve been using all along, however, then totally different story.
September 26, 2017 @ 8:49 pm
I seriously doubt it will show up. Best of luck!
March 20, 2015 @ 3:56 pm
How does the hair test work with taking pain pills???
March 21, 2015 @ 12:13 pm
The hair drug test works the same way for all drugs. The only difference is how far back in time they can detect drug use, because traces of different drugs disappear from your system at different rates. See the table above (Which Drugs Are Detected By A Hair Follicle Drug Test?) for the cut-off times, by type of drug.
April 9, 2015 @ 2:53 pm
Thank you. So drugs do cone out the hair at some point? Depending on what the chart says. Thanks.
May 17, 2017 @ 6:19 pm
Hey how did your test come out and what did.you do
March 24, 2015 @ 10:54 pm
I have a hair follicle test 4-20….(how ironic). I last smoked Saturday. What’s the best and safest method for me to past this test????

If I got to take a hair test in 7days and I haven’t had a drink of alcohol in a month or two will the alcohol show up in my hair? and is there a way I can sweat or use any thing to hide it?
June 25, 2015 @ 2:13 pm
Depends on how much alcohol you used.
In general, yes, they will be able to detect it in your hair if you drank w/in the 90-100 day period prior to the test.
You can try one of the two methods mentioned above (Macujo and Jerry G). They were developed for THC/marijuana, the hardest drug to scrub out of your hair.
Good luck on your test.
February 6, 2016 @ 12:04 am
Did u pass Keece?
March 27, 2015 @ 10:23 pm
If I do the macujo method will it alter my hair color to where they might suspect me of trying to cover any traces
March 28, 2015 @ 8:06 pm
Good question! No, I don’t think the Macujo will alter your hair color much. The Jerry G method is another story, entirely.
February 13, 2020 @ 6:01 am
I did a couple of key pumps of coke, I have a hair test in about a month I’m half. Do you think this will show up? And what can I use to get it out, my hair is pretty short.
February 18, 2020 @ 10:35 pm
Jake, if that’s all you’ve done in the past ~110 days, then you should test clean without having to do anything special. As long as it’s a 90-day test.
April 8, 2015 @ 11:28 pm
Cutting it close. Preferably you’d have 100 days b/w last use and your test. You might want to cut your hair down to 1″ (which should eliminate all traces from Dec 31), and see what the lab does. They might go with the shorter 1″ sample or ask you to come back in a few weeks (which means you’re all clear).
April 9, 2015 @ 12:12 am
Wat about a perm does tht eliminate all traces??
April 11, 2015 @ 1:55 am
I have a hair and urine test in about April of 2016 when should I stop smoking weed?
April 11, 2015 @ 2:39 pm
You’ll need to stop using about 100 days prior to your test. If you quit during Christmas season, you’ll be good to go. To make sure you’re squeaky-clean for the lab, cut your hair down to 1.5″ everywhere on your head a few days before the sample is taken.
Best of luck!
January 11, 2017 @ 2:15 am
If you were in a room with people smoking weed but not smoking yourself, could you detox that same day via pills/drinks so then it never goes into your hair?
Basically can you detox a small amount of weed out of your blood before it makes it into your hair?
I have a drug test in 13 days and I don’t even smoke and I’m worried to fail this test because of second hand.
January 14, 2017 @ 5:00 pm
You can NOT get THC-COOH or THC into your hair follicles by standing and breathing in a room of smokers. That is a myth.
TCH-COOH gets into your hair follicles through the bloodstream and/or from your sweat glands – AFTER a regular dose of THC has been processed by your body.
There is no way you can get a positive-test-level of THC-COOH into your hair via second-hand smoke alone.
This has been studied to death by medical researchers.
April 11, 2015 @ 5:53 am
I tried the home remedy of shampooing with tar shampoo, vinegar, clay and pink salicylic acid. I washed twice daily for a week solid, scrubbed in salt etc. No go!I failed. Applying for jobs and have long hair I would rather not shave my head but wondering if this is really my only option.
April 11, 2015 @ 2:35 pm
There are lots of cleaning procedures discussed online. Not knocking yours, but my research shows that the two cleaning regimens that work the most frequently for the largest number of people are the Macujo and Jerry G methods. Most of the reports are for THC/weed.
April 16, 2015 @ 4:57 pm
I had a very minor amount of cocaine at the beginning of march 2015. I have not used anything since then. I have been keeping my head bicked to the scalp and nairing my entire body on a religious basis. I may have a hair test coming up. Just wondering if the time will be ok, from then to now to let my hair begin to grow out?
April 16, 2015 @ 6:03 pm
Yes, you should be fine. It takes 7 days for the last bit of tainted hair to grow beyond the scalp line. If you’ve been shaving since early March, it’s all gone now.
April 18, 2015 @ 6:00 am
I stopped smoking weed 2 months ago and have been shaving my head every week since then and now I am letting it grow back, so I should definitely be good right? Also is it possible that even if you have enough hair on your head that they could take it from another part of your body?
April 20, 2015 @ 1:03 pm
Yes, you should be OK as long as you have 1.5″ of hair to sample when you get tested. If not, then they may want to sample your underarm or pubic hair.
May 1, 2015 @ 3:34 pm
Actually Jay you forgot one tiny but very crucial detail. Let’s say you’ve been smoking for a month and stopped tomorrow. As you say if you wait 7 days and then shave you will be growing new “clean” hair correct? Unfortunately it’s not like that. You have to completely detoxify your body if any drug in order to shave and grow new clean hair. You having THC in your system will still grow into your hair. So it takes 30-90 days depending how much you smoked for your body to be clean, buy a cheap urine kit, make sure your clean, then you can shave all you want.
May 3, 2015 @ 2:17 pm
Thanks for keeping me honest! No, I didn’t forget this detail – and I agree, it is very crucial. That said, your numbers are a bit off.
According to the National Drug Court Institute (NDCI), the time it takes for THC metabolites to fall below the test threshold of 50ng/L is as follows:
For Infrequent users: 4 days
For Chronic/Frequent users: 10 days
The best strategy is to just stop using 100 days prior to your hair test, if you want 1.5″ of clean hair. But if there’s no practical way to do that, then you need some way to clean your existing hair (this was my friend’s predicament).
More information about this can be found here: http://www.leafscience.com/2014/04/22/how-long-thc-stay-system/
This 2006 NDCI report that explains why the “30-day window” that so many people quote – especially law enforecement – is a myth: http://www.ndci.org/sites/default/files/ndci/THC_Detection_Window_0.pdf
March 5, 2017 @ 11:10 pm
It all depends on your body weight and how often you smoke I’m heavy 250 lbs and smoke a lot everyday so a few years ago I quit smoking for over 2 months and then failed a urin test. As far as I know the thc stays on your body fat and in my case I have lots of it and even after 2 months I failed a urin test not hair
March 6, 2017 @ 4:52 pm
John, sorry, but that’s actually (mostly) a myth.
Body fat does retain TCH-COOH, the metabolite that drug tests detect for use of THC.
However, body fat does NOT “protect you” from a hair test. For example, body fat doesn’t “sponge up” excess THC or THC-COOH, preventing it from entering your bloodstream. Body fat does, however, keep the metabolite in your body, longer.
That said, body fat VERY SLIGHTLY slows down the rate at which TCH-COOH (metabolite) increases in your bloodstream, per dose or whatever. So, a heavier person will need to smoke a LITTLE BIT more to achieve the same trace levels in his bloodstream, in the same timeframe, than a thinner/lighter person would. But that difference is a lot smaller than people think.
May 4, 2017 @ 12:56 am
So your saying wait the 100th day and cut ALL your hair off to make sure it will grow 100% clean?
May 5, 2017 @ 4:09 pm
To clarify: after you abstain for 100 days (light user) or 120 days (heavy), then cut your hair down to 1.5 inches in length (or less), and you’ll be good to go.
May 2, 2015 @ 6:28 pm
My question is that I rarely smoke (1-2x /yr) and I will have a folicle test about 45 days since theast time i smoked. The test will be in 2 weeks. If i cut my hair now will it regrow clean? Or will it take 90 days to naturally clean up? Also i have short hair and do they really need 1.5 inches of hair? Mine is rarely that long ever.
May 3, 2015 @ 2:48 pm
Infrequent marijuana users clear THC metabolites out of their system (below the 50ng/L threshold) within 3-4 days, and it takes about 5-7 days for that newly clean hair to grow through your scalp.
So any hair that pops out of your scalp starting 10 days after your last use is probably clean.
Yes, most labs required 1.5″ of hair. If you don’t normally wear your hair long, then bring photos to help explain. The lab might listen.
But they still need a sample to do their job. So they might do any of the following:
1. ask for a sample from your armpit, pubic region or chest hair.
2. if you’re lucky, they may settle for a Urine test (rare but has happened).
3. elect to reschedule your test, if you agree to grow your hair longer.
But your hair should be clean when you walk in, as long as you shaved down to the scalp 10+ days after your last use.
April 9, 2016 @ 6:55 pm
Hey I took 3 pulls on some pretty good weed and a week later I took 1 pull. I haven’t smoked in two years prior to these two occasions. Do I need to be worried about failing a random hair test within the 90 days?
April 9, 2016 @ 8:28 pm
Probably nothing to worry about. Good luck!
January 28, 2017 @ 12:12 am
how did it work out for you?
December 4, 2017 @ 3:51 am
Any word on this result? I’m literally in a practically identical situation and have to go in tomorrow morning. There probably won’t be a response in time I understand, but I’m nervous nonetheless
May 4, 2015 @ 3:26 am
I am scheduled for a pre-employment hair test. I applied three weeks ago and received an offer and was notified of the hair test one week ago. I have never interviewed with this company so they have absolutely no idea what I look like. In the company substance abuse policy, it says if an employee cannot provide an adequate head hair sample (bald or short hair), they should take leg or arm hair. If they cannot get an adequate body hair sample, then they will use a urine or saliva test. Also, they are told not to take a sample that can be cosmetically detectable where possible (so I am hoping that eyebrow sample is off the table).
I am planning on walking into the facility next week with a short haircut (1/4 inch) and a fully shaved body. I will tell them that I am a swimmer who recently had a meet and 2 weeks was simply not enough time to let me hair grow out to an appropriate length.
Do you think this will work? I can pass a urine test, I just need to get to the point where they offer me a urine test instead of the hair test. The testing clinic is instructed to consult with the company’s HR protocols if an adequate hair cannot be taken. It doesn’t seem like they are really too concerned with automatically failing people they can’t get a sample from.
The toxicology lab they use does not process fingernail samples, so that is not a concern for me.Let me know what you think, as it seems like you have some great experience with pre-employment tests. Also, my other question is, do testing facilities ever shave hair from the body to obtain a sample or do they always trim the hair with special scissors? Thanks!
May 4, 2015 @ 4:13 pm
Scissors or a razor? both are used.
Shaving body hair? yes, they might do that.
Pressing for a urine test looks like the right strategy for your situation.
But if you say you’re a swimmer, then be prepared to provide evidence of a recent competition, where you train, your team, etc. They may ask for this to back up the reason for using an alternative test.
Best of luck!
June 21, 2016 @ 4:11 am
I pretty much took the same approach you did. But instead, I told them that my girlfriend doesn’t like body hair and insists that I shave it off. In fact, my ex-girlfriend made me shave all body hair. So it wasn’t that much of a lie. Anyways they took a urine test because my hair on my head was only bout 1/4 inch long. They sent the sample to a lab and about a week an a half later I received a call from HR of the company I applied for and she tells me I good to go. There was talk about me going back to the clinic once my hair is longer. But, from the conversation I had with the HR lady I’m ok to start. Orientation is in a couple weeks.
Good luck on your test.
May 4, 2015 @ 4:28 pm
This page was helpful, comments and all, but I still would like to ask a few questions. I have a test coming up within the next few weeks, not sure how far back they will look but it’s for a big company. In one of your comments you mentioned a threshold. Do all tests have a threshold of what’s passable/acceptable THC levels? I had a few small hits at the end January of this year, but haven’t had anything since 2011 and since that time I cut my hair significantly so the 2011 levels are gone I presume. I have a weave in now so the majority of my hair is braided up with some is left out, so will they be able to cut a strand from what is left out of my hair? Given the amount I smoked, I’m uncertain about trying some of these methods, but also am not sure about how fast my hair grows since by time I take the test it will be a little over 100 days since I smoked that tiny amount. Should I be ok?
May 5, 2015 @ 5:39 pm
Re. the threshold:
Most hair drug tests use a cutoff of 50ng/L for a chemical that’s produced when your body metabolizes THC. They’re actually measuring the by-product, not the drug (THC) itself.
My bet is that you will test clean, given the info you shared.
For an infrequent or 1-time user, 100 days of hair growth since last use pretty much eliminates the risk for most people.
I can’t speak for your hair growth rate, but I know that African American hair tends to hold more metabolite and grow slower than others, which increases the risk of detection.
Tip: make sure they cut no more than a 1.5″ (90 day) sample *from your scalp line*, which is what they’re supposed to do. The best way to guarantee this happens is to cut your hair down to 1.5″ *everywhere on your head* right before your test.
Best of luck on your test,
May 5, 2015 @ 5:32 am
Hey J, just wanna give you a big thank you for this public service of yours. I’m grateful for the time you’ve dedicated to helping all of us out.

May 15, 2015 @ 4:26 pm
I’ve beaten hair test two different occasions simply using aloe rid , leaving in overnight & immediately dying my hair
June 10, 2016 @ 8:58 pm
Can you tell us where you got the aloe rid ? We’re heating it was discontinued since 2005. Sos please
November 29, 2016 @ 5:44 pm
Which drugs did you possibly have in you’re system?
September 21, 2017 @ 4:03 am
Did you do the Mac method. And are you a light smoker
May 19, 2015 @ 12:01 am
ok I have to weigh in … I’ve worked for same casino 3 separate times now . Every time they took my hair . I am a daily pot smoker & have been for 15 yrs … First two times I used aloe rid . Left it in over night , died hair in morning ( never bleached it ) passed both times . Last time I used “ultra swim” left it in over night 2 nights in row & dyed hair in morning . Again , I passed . It’s not tht complex .
May 19, 2015 @ 11:56 pm
Is aloe rid that expensive one?
January 13, 2017 @ 9:28 am
Do you have to dye your hair as well or can you just use the shampoo treatment??
January 14, 2017 @ 4:47 pm
There are 2 different methods that people use to strip TCH-COOH from their hair:
1. Macujo: shampoo + other cleaners only (no dying)
2. Jerry G: dye/bleach your hair
(learn more about both methods here):
May 20, 2015 @ 11:40 pm
How effective have you read the Aloe Rid to be? It is MUCH more expensive than the other products I have seen, while I’m willing to shell it out to pass this it is a bad though to spend that money and then fail on top of it.
Also, I’ve seen instructions to use the product up to the day of the test. What if you have a week in between use and the test itself because of rescheduling? Would that week in between negate its usefulness? Thanks for this site, I was so relieved to have all this reliable information in one place once I discovered I’d need it!
May 24, 2015 @ 3:25 pm
Of all the shampoos, Nexxus Aloe Rid (old formula) is mentioned by far more people who actually passed the test that any other product.
I wouldn’t wait a week between last shampoo and your test. After 7 days, it’s highly likely that more tainted hair will have grown out.
Best of luck on your test.
June 1, 2015 @ 4:19 am
When buying Aloe Rid, it asks if you want Ultra Clear shampoo or Clear Choice Shampoo for the day of test. Which is the one you should buy?
June 22, 2015 @ 2:56 pm
Buy Ultra Clear.
Need this job
June 2, 2015 @ 5:05 pm
I’ve been a heavy smoker 1-3grams a day of good pot for a long time. Long story short I need to be ready for whatever test (have a feeling it will be hair). I stopped smoking completely exactly 1 week ago and did white May 16th. I’m an athlete fast metabolism very low body fat. I started shaving my whole body a week ago. I’ll probably be tested late next week. If I wait 3 days and cut my hair to 1/2″ and start the mac and aloe rid process, my hair also grows on the faster side. So by 10 days cut my hair down again hopefully cuting off that 1/2″ of tainted hair ill have 1/2″ of clean hair? Or should i forget about cutting my hair and just doing the treatments ASAP. This is amazing position and I can’t lose it please help
June 2, 2015 @ 9:06 pm
Given your history, you aren’t going to win by cutting your hair down to 1/2″ this close to the test.
Shaving completely (all over your body) is the only way to eliminate tainted hair at this point. But that leaves no hair to test…
Need this job
June 2, 2015 @ 11:12 pm
Thank you for your reply. I’ve read using aloe rid for 10 days and ultra clean the day of is 95% successful and no need to do the Mac method. I guess I’ll keep my hair normal length aprx 1″ do both Mac and the treatment. Do you think I’ll be okay? I did lighten up my smoking the past few weeks before I got news of the Job offer but still daily. Thank you again. I don’t know what I’ll do if I lose this position over this. Expense is not a problem when coming to this
June 2, 2015 @ 5:48 pm
Like everyone here we thank you…you’re a Drug Detox Angel! The question I have pertains to the accuracy of whichever testing lab that this company may be using…especially when money isn’t really an issue, mainly b/c LV casino’s have the money to pay for the best labs. So that being said; is it possible that they may be able to detect the use of any of the above detox shampoo’s, and therefore failing me do to using some sort of cover-up treatment.?.
June 2, 2015 @ 8:56 pm
Your welcome 😉
Yes, it is possible they will detect a specific shampoo, especially if you leave it in your hair.
That said, I’ve never seen or heard about a situation where someone failed a test due to using a detox shampoo.
June 3, 2015 @ 11:40 pm
Can you shave your head 10 days after you stop smoking weed or do you have to wait and shave 10 days after your system is clean, like when you can pass a urine test. Just wondering if the bottom of the hair follicle stays dirty until your system is completely clean.
June 4, 2015 @ 12:10 am
Answer: Shave your head 5-7 days *after your system is clean*.
Here’s where the “10 day shaving rule” comes from (for MJ users):
If you are a casual/infrequent MJ user, it takes 3-4 days for the THC metabolites in your bloodstream to drop back down below the 50 ng/L hair test threshold.
So the calculation is:
(3-4 days to clean system) + (5-7 days to grow tainted hair through the scalp)
= wait 10 days before shaving your head.
For heavy MJ users, it can take up to 10 days of abstinence to drop below the threshold. If you fit this category, then you should wait 15-20 days before shaving.
A lot of people still believe it takes 30 days to clear THC out of your system, but that myth was debunked a few years ago. See my comment above for links to the latest hair test science.
June 4, 2015 @ 9:48 pm
Thanks so much for your informitive website. I have a general question that I can’t find the answer to online.
50-55 days ago I did 2 lines of cocaine, should that fall above or below the cut-off limit on a standard hair test?
June 5, 2015 @ 10:45 pm
The cut-off limit is only important when determining how long it takes for a drug to clear out of your bloodstream, so it can no longer get into your hair. From the point your bloodstream is clean, it will take about 90 days to grow enough hair to meet the hair test min. requirement.
Luckily, blood traces for most drugs quickly drop below the cut-off limit within a day or two – including cocaine. THC is the only drug that can take longer, but only if you’re a chronic / heavy user.
As long as your test is more than 90 days from last use (35-40 days from today) and you cut your hair down to 1″-1.5″ (all over your head) right before the test, then you should test clean.
If your test is sooner than that, then bear in mind that once a drug transfers from the blood into the hair follicle, it’s really hard to get it out. That’s why people developed the strong cleaning regimens discussed above (Macujo and Jerry G methods).
Hope this helps,

What if I quit smoking marijuana 13 weeks ago? But have been going to the gym since? Lots of sweating doing lifting and a little bit of cardio 20-30 minutes 3-5 days a week? Also using the Sauna for about 15-20 minutes usually 2 – 2-1/2 hour work outs? Would this help my chances if I have to take a test on June 12th? Also will fitness supplements such as pre work out, protein, and testosterone boosters affect my result?
June 5, 2015 @ 10:26 pm
Working out doesn’t change anything, unfortunately.
Hair is oblivious to your pain. It’s kinda mean that way 😉
If you were using MJ lightly and quit 13 weeks (91 days) ago, then you should have at least 1″ of clean hair at the time of your test (98 days from last use). Get it cut to 1″ or so the day before the test, if you can.
Best of luck,
June 14, 2015 @ 7:07 am
I have been a daily pot smoker for 20 years. I have quit now for 24 days and plan on shaving my entire body and attemp to grow all new clean hair. My question, as a heavy smoker how long should i wait before i shave? Secondly, i shave my head and will likely have to have my sample taken from my arm pit, chest, arm, or leg hair. Is there a different waiting period for that. I can grow a beard out thay long and may take that route. Btw you are freaking awesome for helping people that are turning things around and doesnt want the past to haunt them.
June 15, 2015 @ 1:01 pm
The latest research says that if you are a chronic/heavy smoker, it takes about 10 days for THC-COOH (the THC metabolite detected in the test) to fall below the minimum threshold in your bloodstream. Once the blood is clear, it takes 5-7 days for the last bit of tainted hair to reach the surface of your skin.
So, to grow 1 1/2″ of clean hair for the test, you’ll need 117 days between the time you quit and the test.
Body hair tends to grow more slowly than scalp hair, but growth rates differ by person and unfortunately I don’t know of anything specific to guide you waiting times there.
Facial hair is considered body hair.
Generally speaking, the lab will prefer testing body hair sampled from above the waistline/pubic region, due to the chance that hair lower than that was contaminated by urine (false positive).
October 24, 2015 @ 7:38 pm
Does that mean that if you did something less than 5 days ago it will not reach the scalp for the follicle test?
October 28, 2015 @ 6:02 pm
Yes, it takes 5-7 days for tainted hair to grow through your skin.
June 17, 2015 @ 4:27 am
I did .4 grams of meth over a 4 day period starting April 29th. I had not done any for a month prior to this incidence. Will the amount in April show up early to mid july? Also my husband had a mess up around a month ago. I shaved his head down almost to the scalp and plan to do it again in a week or so, will this remove any traces of use? Also if he was to shave the rest of his body would the body hair that grew back have any traces of drug use?
June 20, 2015 @ 3:39 pm
Re. you: yes, your drug use will probably show up in a normal (1.5 inch strand) hair drug test.
Re. your husband:
You have probably removed all traces of drug use from his scalp hair at this point. If you shave his entire body right now, you would probably eliminate all traces from his body hair, as well.
BUT… the standard hair test requires the lab to take 1.5″ of hair from the scalp, so they can test for 90 days of drug use. If the lab cannot get that much hair from your husband’s head or an equivalent amount of body hair, then they may fail him for tampering (esp. if they see he shaved his entire body). If you swim competitively, then tell the lab because that’s a good reason to shave your entire body. Otherwise, you are at risk. If you are lucky, they’ll just defer his test until he has enough hair; or, they’ll opt for a urine or blood test, instead.
June 17, 2015 @ 4:53 pm
Jay, I need help have a test Monday I smoked a little and did a little powder on 5/30/15. On the 6/5 I cut my hair down to a 1/4 inch or less and shaved my whole body. I have a test on Monday 6/22 will I be clear? Also can they take hair from my eyebrow
June 20, 2015 @ 3:41 pm

June 18, 2015 @ 5:49 pm
First thank you jay for all the info were all very fortunate for your knowledge. I have a question I last smoked maybe 4 4\12 months ago and have to take a hair test would I be clean if they took it off my leg
June 20, 2015 @ 3:29 pm
If you haven’t shaved your legs since you quit, then yes, technically, there is a trace of THCOOH (THC metabolite) in your leg hair right now. Whether it’s enough to fail you depends on whether you smoked only once back then or were a heavy user.
THAT SAID… for men, the lab probably won’t sample any hair below your belly – it can get contaminated from urine over time, causing false positives.
Best of luck,
June 19, 2015 @ 10:03 pm
So, in the past few years i have been a heavy smoker, at the most a gram a day. About a month or two ago I quit, but I did smoke last week. I am not a cocaine user, but a week ago I did a bump, we’ll call it a moment of weakness. Well, I got the notice today that I am required to submit to a hair follicle drug test by August 3rd, and again October 1st. Is there anything I can do in that time to pass? I was under the impression that the test went back further than 90 days. Either way, it will not have been 90 days by August 3rd.
June 20, 2015 @ 3:22 pm
Your situation is exactly why people invented the Macujo and Jerry G hair cleaning regimens. This page explains the pros/cons of each method, directions and supplies you’ll need.
June 20, 2015 @ 1:23 am
I was a very frequent user until the end of April that’s when I stopped completely. I cut my hair about a 1/2 inch maybe even shorter and bleached it on the first of this month not to alter the test but just for a New look. My job gave me a random drug test yesterday and I’m just wondering do I still have chances on passing it?
June 20, 2015 @ 3:49 pm
Yes, you have a good shot at passing a test for THC – assuming the lab will accept your short hair. Usually, they require 1.5″ minimum to see back 90 days. Lab’s discretion.
June 20, 2015 @ 1:37 am
JZ, your awesome!!! Im curious…Ive been taking pain meds for years now. I quit taking them last Wednesday the 10th. How long should I wait to take a hair test? Ive got a good opportunity and Im trying to do this correctly. Thanks
June 20, 2015 @ 3:45 pm
To be completely safe, you should wait 110 days after you took your final dose, then cut your hair down to 1.5″ all around your head a week or so before your test.
June 20, 2015 @ 1:49 am
BTW JZ, the company did confirm a hair test and said they will go back 90 days.
June 21, 2015 @ 11:57 pm
Hi, I am a female with long hair (below my shoulders) and was a regular smoker for years up until last summer. I’ve smoked occasionally since then, in Decemebr 2014, February 2015, and most recently May 2, 2015. I will have a hair test in 3 months in October 2015. Is it necessary for me to cut my hair to 1.5″ – I know that is required for a test but will they test more than that amount if I have long hair? Thanks
June 25, 2015 @ 2:21 pm
Most labs won’t test more than 1.5″ due to well-known test reliability issues on longer hair. They are instructed to cut from the scalp line up.
Your employer could order a longer history, but it is a much more expensive process that few choose.
The only failsafe way to protect yourself is to cut your hair to 1.5″.
Hope this helps,
June 23, 2015 @ 4:59 pm
I wish I could’ve been to this website earlier. I just got done with the clinic cutting my hair and they will send it tonight. For the second time in my life I took 3 hits off Joint last week and tried coke for the first time ever 3 months ago……. Most likely I will fail and not be hired. Very upset at myself. If I fail could I do a retest? Would I pass if I trim my hair down and leave about an inch ?
June 23, 2015 @ 9:08 pm
I don’t want to give you false hope… but there’s hope for you, I think.
Retests usually only happen if there is a good reason to believe that your hair was contaminated in some way.
Let’s break down your risk into the two drugs you mentioned:
1. Marijuana – 3 hits, 7 days ago:
There is almost nothing that can contaminate hair that mimics the THC metabolite they test for, so retesting is probably a non-starter if you test positive for weed.
On the other hand, you used very little about a week ago. Two good things about that:
– 3 hits may not be enough to raise your blood level of THC metabolite above 50ng/L, the usual cutoff. Depends on the strength of the bud.
– It takes 5-7 days for any traces of the metabolite to make it from your bloodstream (time of use) into your hair and through the surface of your scalp, where it can be tested.
Net-net: there is a decent chance your hair sample isn’t tainted w/ enough THC metabolite to show up on a hair test.
2. Cocaine – light use 3 months ago:
Sounds like your hair is longer than 1″.. but if it wasn’t much longer – or the sample they took was 1″ or less – then you have a shot at passing, That’s because 90 days is enough time to clear the drug out of your system and grow 1″ to 1.5″ of clean hair through your scalp.
If you fail for cocaine, then you may be able to qualify for a retest if you recently used or have any of the following:
– Coca tea, Coca leaf, Coca flour, Coca oil (all banned in the US)
– Kidney disease
– Tonic water (a LOT of it)
I sure hope you squeak through!
June 24, 2015 @ 9:21 pm
I did 4 small lines of meth in the past 2 days. I haven’t done anything in the past 4 years. I have a hair follicle test in two days. I just went and bought a product called stealth shampoo to try it out. The last time I did a hair follicle with this company they took it from my legs because my hair on my head is to short. Please help!!!!!!
June 25, 2015 @ 2:17 pm
If the time between your ONLY use and the test is only 4 days, there’s a decent chance you’ll pass- because it takes 5-7 days for tainted hair to grow through your scalp line.
Crossing my fingers for you.
October 3, 2017 @ 6:26 am
Did u pass?
June 25, 2015 @ 1:50 pm
I was wondering where you buy aloe rid or the other shampoo. And does it work and what other works on methanphetamiens
June 25, 2015 @ 2:09 pm
You can still find the old formula of Aloe Rid at TestClear.com
I know people use it for lots of drugs, but the only strong evidence I’ve found is for THC/weed (the hardest drug to detox).
June 26, 2015 @ 6:49 pm
Soo, I kinnnnda quit smoking over a month ago (smoker since 2011, smoke 1-3 baby hits a day everyday)…BUT, now I’ll take 1-4 baby hits a week- usually when I get tipsy with the hommies on the weekend. I have hair down to my chest & it is beautiful,thick and brown- && I do not want to die it/cut it or anything….
I have a hair test coming up soon (1-3 weeks) IF I get this job offer- which I am pretty confident about!
Will simply using Aloe Rid (Leave it in over-night maybe twice before the test) and then using the Ultra Clean the day of the test be most effective? Or, do I still need to dye my hair (not bleach, but just dye)???
I read an earlier post from a girl stating she used the Aloe Rid over-night and then just dyed her hair a normal color && she passed her test.
BUT, I just do not want to dye my hair PERIOD because it is big, beautiful and it took me years to get it this long!!!!!!
Please help! Thanks!
July 2, 2015 @ 9:15 pm
Unfortunately, the only two methods I know of that have a decent track record are the Macujo and Jerry G cleaning regimens.
For Macujo, Aloe Rid is just one of the ingredients – you need the other ingredients, too.
Hope this helps,
June 28, 2015 @ 4:20 am
Does an extremely slow hair growth rate or hair that has peaked its maximum length skew the timeline in which a hair analysis determines that exposure occurred. For example lets say a hair sample is taken from someone who has an extremely slow rate of growth for their hair due to a combination of document-able causes. Specifically where an 1 1/2 of hair truly represents a much longer time frame of growth than the average of .5 inches per month. Therefor, could the positive test result actually be showing exposure from a much longer time frame than that of someone who has hair that grows at the typical rate? If so do have documentation or information that you could point me to?
July 2, 2015 @ 10:04 pm
VERY slow growing hair could show up to 120 days of drug use.
That’s because human head hair grows at different rates. But not THAT different.
Everything I’ve read says human hair grows between 1 to 2 inches every 90 days – this covers almost everyone.
In a 2005 study published the International Journal of Dermatology, scientists found a difference among races in the rate of hair growth.
– African hair grows the slowest, as slow as 1″ every 90 days.
– Caucasian hair grows faster, about 1.5″ in 90 days.
– Asian (Mongolian) hair grows the fastest, as much as 2″ per 90 days.
– growth rate of male hair doesn’t differ from women
– there is some seasonality to hair growth – your hair grows a little more in the summer – but the amount is so slight, it’s not worth worrying about
Yet again, African Americans get ‘the shaft’ (sorry for the pun)!
I am not a doctor, so there may be rare diseases, etc. that also make a difference.
Hope this helps,
July 1, 2015 @ 10:42 pm
Just quit smoking about 30 days ago so I could get a better job. I Smoked at least twice a day for a year. Gonna wait till day 100 and then shave everything off. Then wait till it grows out to at least an inch and a half before applying. What are my chances of passing a hair test after this horrifically long process?
July 2, 2015 @ 9:09 pm
Yes, waiting 100 days blows. But your chances are excellent, if you do. 😉
April 19, 2016 @ 7:29 pm
Just leaving a line to say you americans are really lucky..
I am in your same situations but let me tell you how the hair test works in Italy.
First off, our cutoffs are 0,05 ng/mg THC and 0,0002 ng/mg THC-COOH.
Second: our hairs need to be long enough to detect use in the SIX MONTHS priori the test.
Third: our labs do detect if the hair has been colored and the test results invalid. Hence, we are unable to use the Macujo method.
Now, maybe i’m missing something but.. I think it’s a shit here.
Good luck you All..
July 9, 2015 @ 12:55 pm
Hello Jay! Although this site has so much useful info ( the only one! Thanks for all of this) I just still cannot find what I am looking for!! SO…. I am in art school for photography, not cheap. Luckily my husband is willing to get a better job to help me kickstart my career. Problem is the new job screens the guys like they are secret service watching the gold.. They are going to do a 6 month hair test on him…. He quit smoking pot 5 1/2 months ago.. You think he will pass?? How can they even go back 6 months, if it only stays in your hair 3!???
July 12, 2015 @ 5:23 pm
To clarify: Drug traces stay in your hair forever – they don’t disappear after 90 days. That’s why you need to cut it down to 1.5″ or so before the test.
A 90-day history is what most hair tests look for, but some employers will test further back.
Hope this clears things up.
And good luck!
July 11, 2015 @ 11:13 pm
Just wanted to say ur site is awesome bro… Keep up the work, lol love it
July 12, 2015 @ 8:27 pm
If you have been prescribed pain pills and have the bottle to prove but have taken more than you were prescribed will it show up how much you’ve taken or will it just show that you have done it?
July 19, 2015 @ 4:36 pm
The lab can see how much you used, and roughly when. So, yes, they can probably detect if you used more than prescribed.
July 15, 2015 @ 4:17 am
Hey. I got a position in a great company as a “future associate” in about 58 days they will offer me a position. Thing is they want a hair sample for drug test. I am a HEAVY weed smoker. If not every day, every other day. Sometimes 1-4 grams a day. It sucks to say but I can’t stop smoking. Been smoking for 10years plus only stopping maybe 30-60,days years ago to stay out of jail. Im wondering do they test levels?? Or do they just see THC and u fail??
July 19, 2015 @ 4:33 pm
They test levels. The chemical they look for is a THC metabolite (not THC directly). 50ng/L is the usual threshold.
July 16, 2015 @ 3:31 pm
So what about edibles (weed browmies)? like i only do it every blue moon and jus got called for a Job i tried to get like 6 years ago. my test is Monday and im freaking out cause i know thats not enough time to order this stuff online. any suggestions?
July 19, 2015 @ 4:29 pm
Sorry to tell you this, but there’s no diff b/w eating or and smoking THC.
Crossing my fingers for you,
July 16, 2015 @ 5:03 pm
im an african american male with really short hair (under an inch) but have a beard. im sure there is weed in my system and feel like i should shave my beard. if i do so where else will they pull hair from and will them taking it from somewhere else better or lesson my chances
July 19, 2015 @ 4:28 pm
They can sample hair from anywhere on your body. Body hair grows slower than head hair. Usually they’ll try to take chest hair, facial hair or hair above the waist.
See the chart above for the limitations that the test lab has to deal with for each part of the body.
July 17, 2015 @ 1:13 am
Great site. Tons of useful information. Thank you for taking the time to address the needs of thousands.
July 27, 2015 @ 4:25 pm
I’m wondering because of the long time involved for the drugs to enter your hair it seems to me cleaning the day off the test would actually provide the best results. Is this true or false?
August 5, 2015 @ 12:50 pm
Yes, it’s a good idea to clean your hair the day of the test.
August 6, 2015 @ 11:57 am
I’ve never been a big smoker but take a couple hits from time to time. I just happened to smoke twice in the last 5 days each time a couple hits. Once on Saturday and again on Monday.
I’m seeing it takes about a week for the hair to pick up the thc, my question is:
Is there anyway I can detox before the week is up, so it doesn’t have the chance to get into my hair?
I just got offered an interview. So I’m not sure when the testing will come but I’m sure it will be in the near future.
August 7, 2015 @ 2:52 pm
Sorry to tell you this, but new hair gets tainted within minutes after you take the first hit. It takes 5-7 days for the new tainted hair to grow through your scalp.
Not much you can do about this, until the hair grows out and can be treated or cut.
Best of luck,
August 10, 2015 @ 5:37 am
I haven’t snorted coke in like 5 months and I’m trying to get a job and they are now doing hair follicle test. Will I pass or will it still me in my hair?
August 12, 2015 @ 11:32 pm
Once a drug or drug metabolite gets into your hair, it stays there until you cut it out or clean it out.
In your case, you should cut your hair down to 2″ or so all around your head right before the test – to eliminate any traces of drug use recorded in your hair from 5 mos ago.
Best of luck on your test,
August 10, 2015 @ 7:49 am
Hi JZ, first just want to say thanks for providing a site with real useful information, it really is a great help to many of us.
I smoked a tiny amount of meth residue that I scraped from a pipe around 25/07, it would not have even been 0.01 of a gram. I possibly need to take a hair test sometime in the next 2 months. This one time use will be the only time I’ve used drugs in the 90 days prior to the said test.
What I want to know is will a hair follicle test pick up such a small one time use? I’ve read on some forums that it won’t. If I need to clean my hair to pass the test but I can’t afford aloe rid what is my next best option for cleaning the meth out of my hair?
August 12, 2015 @ 11:29 pm
If you’ve only done a total of 0.01g during the 90 days prior to the test – and you cut your hair down to 1″-1.5″ right before the test (to eliminate any use prior to 90 days), I seriously doubt you’ll test positive for meth.
August 12, 2015 @ 12:15 am
Hey JZ so I have a question for you I stopped smoking August 7th I’ve been smoking probably everyday for about a year I have a hair drug test for my current employer in about 3 months, on August 6th I also did I would say probably a 40 bag of cocaine on my friends birthday and only did a line once before that like a few weeks prior I’m deff not a frequent coke user but deff a frequent weed smoker, so I cut a lot of my hair off today I got a haircut nice and short and I plan on shaving my body hair too soon an getting a few more haircuts will I pass my hair drug test if I stop for 90 days while getting frequent haircuts? I’m paranoid I’m going to fail for cocaine not even the weed because that looks a lot worse what do you think?
August 12, 2015 @ 11:19 pm
Once a drug is in your hair, it stays there until you cut the tainted section off (unless you do really aggressive cleaning). Doesn’t matter which drug it is.
That said, given you are ~90 days away from your test, you have a good shot of passing if you completely abstain from now on, and cut your hair down to 1″ right before the test (less than 1.5″).
Best of luck on your test!
August 12, 2015 @ 4:53 am
Are there any ‘religious’ or ‘medical’ reasons that you can say to not have to take a hair test?
August 12, 2015 @ 11:12 pm
Not that I’m aware of.
Know some stuff
July 21, 2016 @ 6:39 am
Yes, if you’re immediate family members have died, it is against the Jewish religion to cut hair or nails
August 12, 2015 @ 4:29 pm
So, first I would like to thank you for all the useful information. At this time i self medicate and take 3-4 methodones a day to avoid opiates. I was offered a position at a well known chain company where the opportunities are endles. However I have long hair that is down my back. I will need to pass a hair test in 3-6 weeks. Do normal hair tests.show methodone use or suboxone for that matter? Thanks in advance.
August 12, 2015 @ 11:01 pm
As the chart below shows, most serious hair drug tests (10-panel or higher) can detect Methadone use for up to 90 days.
It’s less certain if your test will detect Suboxone use. As you can see below, some of USDTL’s tests do, some don’t.
(ref: US Drug Laboratories website)
For cheaper tests like 5-panel or 7-panel screens, Suboxone is not one of the drugs included.
Hope this helps.
August 12, 2015 @ 11:04 pm
What a fantastic font of knowledge you are and so generous with your time & info.
That being said…I am/was a chronic mj user…quit about 5 days ago…I want to apply for a job that i know utilizes the hair follicle test. I don’t have a whole lot of hair on my head as it is…and i feel it grows slower than what has been stated here..though maybe i feel that way when it doesn’t grow in where i would like…this may sound dumb…but can you use the head hair cleansing regimen on body hair…is that even possible? Or should i wait about 2 weeks shave my head and then just bite the bullet and wait for it to grow to 1.5″?
Your input into this matter would be greatly appreciated!
August 12, 2015 @ 11:23 pm
The cleaning regimens should work the same on any type of hair, although the side effects & burning may be very unpleasant and possibly unhealthy for some parts of your body (Jerry G method especially).
If it were me, I’d bite the bullet and wait it out.
August 14, 2015 @ 6:07 pm
I passed the Hair Test! Thanks Jay Z. I really appreciate this site! I feel compelled to tell how I did it since all the advise and comments helped me a bunch….I was a daily user and used the good stuff. Age 51 with thin brown hair and lots of it.
I was clean for 30 days as I thought it would be the pee test. Had a week to prep for the pre-employment test via phychemedics. I used the Macujo method as described.
Also my wife’s hair dresser stated one of his clients had 4 or 5 hair tests he passed for a court custody problem. He said he recommended he use the Malibu swimmers treatment with a Redken cleaning shampoo of some type.
I bought the Malibu swimmers treatment (Crystals in the pouch) and used it once a day for 5 days straight. Had the Aloe Rid old formula so I used it instead of Redken’s.
Used Mac Method in the AM and PM and swimmers treatment at noon. So 3 treatments a day for 5 days.
Left the Aloe Rid on for two nights overnight during that week.
One thing I should also have done, but did not, was cut hair from 2.25 inch to 1.5 inches. Also should have colored hair. I already color my hair as it is Grey 25%. I had colored it about 3 or 4 weeks prior to the test.
Good luck to everyone having to go through this. The waiting and anxiety is the worst part.
Also Pray on your knees to St Jude, St Anthony, St Joe and the Almighty. Ask for a miracle if you need one.
September 1, 2015 @ 11:02 pm
Awesome news! Thanks for sharing your experience.
August 19, 2015 @ 10:58 pm
How would i know if I bought the new nexus aloe rid shampoo or the old one??
September 1, 2015 @ 11:01 pm
The old Aloe Rid formula has a barcode number of 05592 16035 on it.
If the number is different, then it’s not the right formula.
BE CAREFUL if you’re shopping on Amazon! People have paid for the old formula, but received the new formula instead (WHICH DOES NOT WORK).
The only safe place I know of to get it is Testclear. Testclear bought-up the remaining inventory when Nexxus quit making the old formula.
(Use the link above).

I know everyone says they seldom smoke but it’s true. I take a few hits 2-3 times a year of weed. I took a few hits off a blunt in January and a couple of hits in Early April. I haven’t smoked since then . I have to take a hair test in 4 days. If I do the bleaching method could I possibly pass?
September 1, 2015 @ 10:50 pm
Yes, I think your chances are pretty good.
August 30, 2015 @ 1:06 am
Someone who I know smokes pot heavily and takes pills was able to pass a 10 panel hair strand test. They took the test about 20 days after they found out they had to? How did they pass? I thought it was impossible to fool a hair test. They may have to do a nail test now. Is that tougher to pass? Is there any chance to pass it?
September 1, 2015 @ 10:55 pm
I don’t know what they did, but I’ll bet it was one of these two methods.
Hope this helps.
September 3, 2015 @ 5:55 am
I looked through a great many comments but could not find what I was looking for. My situation is not with employment. But rather probation. I was clean from methamphetamines for 17 months and fell off for about a week.I had a hair test scheduled as a condition for early release and cancelled it myself, confessing to the use. I am scheduled another hair test in 90 days. Which will be 92 days or so after last use
I have a couple questions.
Do you know if law enforcement typically tests further back than 90 days? I am a man with maybe 2 inches of head hair but more arm/body hair than could be shaved without notice from my probation officer between now and my test. My thought is that the most reasonable course of action is to not cut my head hair and treat it to ensure they don’t take hair from anywhere else. Tell me if I’m wrong.
The other question is what info could you share about synthetic marijuana AKA k2 ? By the time I have my test I won’t have used any for 100 days but I didn’t see any info on how it works with hair tests, or if it can be tested for at all.
You are by far the most knowledgeable person I have encountered in this area.
Oh some info on the law enforcement question. I live in Texas, in a rural county, in no way a major city. Don’t know if those factors affect how law enforcement deals with hair samples but I wanted to be thorough.
Thanks in advance.
September 13, 2015 @ 7:45 pm
Sorry for the late reply.
Great questions. Let me paraphrase and answer each one, best as I can:
1. Do law enforcement officers test further back than 90 days?
YES, if they think it’s in the public’s best interest. The hair test CAN detect drug use for up to 12 months. There are known accuracy problems w/ testing further back than 90 days, however – so ask your lawyer about challenging the results if they test that far back.
2. Most reasonable course of action…?
I disagree. I’d cut your head hair back to maybe 1″ total length at the time of your test. Labs often accept hair samples less than 1.5″, because head hair grows at different rates for difft people, and they know that. The min. length acceptable depends on what law enforcement/judge/parole board deems necessary, in your case.
Body hair grows more slowly than head hair, so an equivalent length of body hair holds a longer history of drug use than head hair. If you’ve never waxed or shaved your body – now’s a good time to start.
3. Testing for synthetic marijuana/K2?
I did some research on this. In general, hair test labs can’t detect most synthetic cannabinoids – there are hundreds today, with more released each month.
Labs focus on detecting the most popular molecules only, which include:
XLR-111 – a popular new strain that’s causing a lot of ODs.
Problem is, it’s unlikely you know which of the 500+ synthetic cannabinoids you ingested. If you do know (and you’re sure), then check it against the list above.
NOTE: I can’t guarantee this is a complete list. I compiled it from various drug testing lab sites.
4. Rural vs. urban law enforcement practices? I don’t think this makes much of a difference. Most use the same labs.

is aloe rid old formula and ultra clear the best treatment for meth? thaks a bunch
September 13, 2015 @ 7:10 pm
The Macujo method that uses Aloe Rid was designed to strip THC metabolites from hair.
Since THC is the hardest drug to strip from hair, my guess is Macujo works even better for other drugs that are harder to detect – like meth.
I will do some more research and update the page on what I find.
September 10, 2015 @ 3:23 am
How long does it take for cocaine to get out of the hair root. I haven’t used since February 17th until august 1st I only used once but it was about $300 worth so how long will it be before that is out and how long does it stay in the root I heard 1 year.
September 13, 2015 @ 7:00 pm
Traces of cocaine will stay in your hair until you cut the tainted hair off.
You can reduce your risk by stripping your hair with chemicals/bleach.
Hope this answers your question!
September 17, 2015 @ 5:14 pm
Jay I speak for everyone in saying thank you, I know this is probably frequently asked but my buddy use to be a heavy smoker but in the past year has only smoked 5 or 6 times. Around the beginning of August he smoked a gram of MJ and swallowed around a half a gram of Molly and could possibly be hair tested at the beginning of October. What is the best action to take at this point for a chance of him coming out clean?
September 21, 2015 @ 7:28 pm
Your friend sounds like a perfect candidate for the Macujo or Jerry G cleaning regimen.
Best of luck!
October 27, 2015 @ 10:34 pm
Just 1 question ❔ man… I have a test next Wednesday… and I am. A bald guy… where would they take hair from? ..I do havr a beard and mustache though… can I use any methods for my facial hair?
October 28, 2015 @ 6:15 pm
Yes, they may sample facial hair if nothing else available.
Methods are same for any type of hair, although body and facial hair grow more slowly than head hair. 1/2″ of beard can hold 2-3 mos of history.
Best of luck,
November 12, 2015 @ 11:17 am
OMG I PASSED i got my results yesterday im still in shock this has saved my life litrally
November 22, 2015 @ 7:30 pm
What do you do??
November 24, 2015 @ 7:20 pm
what method did you use?
November 15, 2015 @ 3:38 am
Question about when the standard 90 days for 1.5″ of hair starts from last use.
From Oct 15-24 I smoked most of the day ever day (3/8 oz) after not smoking since the previous new years. I have a drug test coming up in mid-late January or early February so I figured I would be in the total clear by a long shot, turns out the company literally just changed policy from urine to hair follicle testing! Never would have even thought about smoking had I known this a couple weeks ago. Does the standard 90 days start AFTER having a totally clean system (for worst case say November 23 for Oct 24+30days to clear my fat) or 90 days from Oct 24th?
November 19, 2015 @ 3:39 pm
You should test clean ~90 days after your blood is clean (below threshold).
November 15, 2015 @ 4:21 pm
Fyi for everyone if you shave all body hair they will take fingernail and or toenail clippings to run the drug test… thought everyone should know
November 19, 2015 @ 3:36 pm
Yes, you’re right. Nail clipping samples are taken sometimes when no hair is available.
Thanks for sharing,
November 18, 2015 @ 11:40 pm
1st thank you for your help to all these folks. Very informative. I am a daily smoker -avg 3.5g/wk for 10+yrs. Anticipating a potential hair test Jan ’16. Would stopping now alone be effective? I suspect not…that stopping & shampoo & color would be the best plan. :/
November 19, 2015 @ 3:30 pm
I think you know what to do 😉
November 20, 2015 @ 5:18 am
Hey Jay – Ok, final try and final question that is totally perplexing to me. Lets say a company wants to test back to a year…how can they do that if the hair sample is only say 2-3 inches? Additionally, say that 2-3 inches was after 90 days, and was cut during that time and at the end of it. Many thanks man!!!
November 28, 2015 @ 2:15 pm
No lab can test beyond the length of hair available to sample.
Human head hair grows about 0.5 inches per month.
1.5″ of hair is required to see back 90 days
6″ of hair is required to see back 360 days (1 year)
The math here is VERY simple (as you suspected).
November 23, 2015 @ 2:12 pm
Did the Jerry G Method after being a daily user. Followed to a T down to ammonia based hair coloring. I did not pass, with 14.1pg. Dark hair, caucasian
If you use pot daily, you have to stop before you even apply. I can’t stress this enough. You have no chance against Psychemed if you are a heavy user. I only had 2 weeks of clean time, one before I applied and one after because I didn’t think I would get the interview and pre employment started so quickly.
Beat advice. Just quit for awhile.
November 23, 2015 @ 3:42 pm
So I don’t smoke, but about a month ago a friend blew two hits of pot smoke right in my face, I didn’t get high, but I have a hair follicle test Friday and am worried it may show up, am I being ridiculous?
November 28, 2015 @ 1:42 pm
No, second hand smoke won’t cause you to fail a hair test.
November 24, 2015 @ 1:09 am
Hi Jay Z, love the site! So approximately 40 days ago I took 4 hits of weed and drank some weed pop for the first time in years. I have a hair drug test in two days. How are my chances of passing would you say?
November 28, 2015 @ 1:43 pm
Pretty good. Single use usually doesn’t show up on a hair test.
January 23, 2016 @ 5:33 am
Did you pass your test
November 28, 2015 @ 1:02 am
I am an occasional pot smoker who has sporadically used cocaine a handful of times over the last 90 days (last time being a week ago) and Molly once (on October 31st). I am facing a drug test next week if my interview on the 1st goes well. Coincidentally, I keep my body hair shaved for some side modeling gigs I have occasionally.
If I understand this correctly, if I walk into next weeks interview with a very short haircut (less than 1.5 inches at any point of my head), and wear the same short haircut to the drug testing facility, they will be unable to sample my head hair, at which point they’ll find that I have no testable body hair?
I am confident I’ll pass a urine test based on the infrequency of use, so would I not at that point be safe from the hair test? Or at the very least buy myself some time until they would want to retest my hair?
November 28, 2015 @ 1:49 pm
There really is no single “industry” answer to your question.
How they deal with a “Mr. Clean” situation depends on the lab’s own policies plus the terms of the agreement they have with their client (employer/govt. agency) about what to do when no hair samples are available.
Sometimes, a lab will revert to a urine sample. Other times, they’ll reschedule to give your hair time to grow.
They might also sample your eyebrows, which many people overlook.
December 18, 2015 @ 4:30 pm
I never smoke weed but i took about 4 hits off a bowl on November 2nd have to take a hair follicle test on December 31st do you think i will be okay or should i try one of the methods? Also i drink a lot do they test for alcohol?
December 22, 2015 @ 9:51 pm
I think you’re safe. A single use, even 4 hits, usually won’t generate enough THC-COOH to register on a hair test.
January 10, 2016 @ 12:25 am
So I have a problem. Last time I smoked was 2 months ago and I have a test coming up on Fed.13. What can I do to make sure I pass.
January 15, 2016 @ 7:08 pm
If you’re a moderate or heavy smoker, then read this page: https://hairfollicledrugtest.info/thc-detox-clean-hair-home-remedies/
January 11, 2016 @ 11:56 pm
Howdy, I did macujo and passed a hair test, have not used and another hair test came up 1 month later. Is my hair still clean?
January 15, 2016 @ 7:05 pm
If you haven’t used since then, then I would presume so!
January 12, 2016 @ 2:09 am
I’ve read through a lot of comments and nothing compares to my situation. I haven’t done any drugs in over a year (since Nov 2014) I bought 2 hair tests (90 day) from hair confirm… Back in September I sent 1 of the tests back for screening. I have a crew cut type hair cut (1/4-1/2 inch) and very lil body hair so I used my beard hair (1-2 inches) long…and I failed for cocaine levels at 20,000!! after 9months clean…(very upset and confused) so I then say maybe it was left over from the 9 months prior and I shave my entire body and wait for my beard to grow back out (1-2 inches) I recently around 3 weeks ago sent my second test out, know and behold still positive for Cocaine metabolites…. This time levels at around 1500… I cannot for the life of me figure out how these levels could still be at 1500 or even in my system after over a year! Can cocaine be ingested through skin contact or airborne? Please help with any information maybe I missed or could turn to. Any information would be appreciated.
Thanks in advance
P.S. The purpose for all this is a government job that I failed 4 years ago for the same situation and the job opening is available for me if able to pass this seemingly impossible test.
January 15, 2016 @ 7:04 pm
Hey confused. There’s very little chance your prior use would show up in your hair after that long, with hair that short.
It is possible that another contaminant is being mistaken for cocaine. Some medications and medical conditions can trigger a false positive for cocaine.
Topical anesthetics derived from cocaine (does not include lidocaine or novocaine)
Another possibility for a false positive is ingesting coca, the plant from which cocaine is derived. Coca leaves, particularly when brewed as a tea, are popular in a handful of countries but banned in the United States.
December 4, 2017 @ 2:10 am
I Recently had a drug Test For cocaine (I have never Taken this drug In My Life )and It showed positive both for the parent Drug And The metabolite ,My solicitor Argued the result ,but was told That There is No Way of showing A false positive ,I obviously know there is ,but the Drug Testing Company Refuses To admit there infact wrong.
December 5, 2017 @ 10:14 pm
Some medications and medical conditions can sometimes trigger a false positive for cocaine. These include:

January 13, 2016 @ 3:52 pm
Mr. Z, I snorted some coke on 12/24/15 and have a hair test on 3/21/16. I’m African American and I have little body hair (leg, chest or arms) and I wear a low hair cut. If I get a haircut right now Will the hair that grows out of my hair pass the test??
January 15, 2016 @ 7:00 pm
Probably, but you are cutting it close for someone with coarse dark hair, because that type of hair grows more slowly and therefore stores a longer history of use per inch of growth.
January 14, 2016 @ 9:27 pm
I smoked pot back in November for a few days then again in December quite December 13 th. Did meth off and through November and quite the 30th of November. If I cut my hair off all over today and do it several times this month will I be clean or is there a product I should use. I don’t have a test at the but I will in a month
January 15, 2016 @ 6:52 pm
The problem w/ cutting your hair now, for a test in a month, is that it will be too short to provide the lab technician with a 90-day sample – which requires 1.5 inches of hair, minimum.
When they see your short crop, they may opt to sample your body hair (which records a longer history per inch than head hair) or they may fail you outright.
You seem to be an ideal candidate for the Macujo or Jerry G cleaning method – see detailed instructions for both on this page: https://hairfollicledrugtest.info/thc-detox-clean-hair-home-remedies/
Good luck with your test!
January 27, 2016 @ 5:37 pm
Nothing quite matches my situation either. I’m applying for a job where they will most likely test me within the next week. Last semester I took vyvanse (and a lot of it) to study with my most recent time being a month ago. I’m not prescribed vyvanse and even if I was i think they could probably tell that I had way over the recommended amount. My question is if the Macujo or Jerry G method would work even though I am not dealing with marijuana. (I’m also a broke college kid and cannot afford the aloe option which seems the best so far). What should i do?
February 4, 2016 @ 8:14 pm
The methods will work for any drug, is what I’m told. However, almost all of the evidence I’ve seen is for THC (weed). Marijuana is the toughest drug to get out of your hair.
November 18, 2016 @ 6:59 pm
Did you end up passing your test?
February 1, 2016 @ 2:39 am
I took a puff on nov. 25 and I haven’t smoked since, I have a follicle test coming up on Feb. 8, do you think it will show up on the test? I had also not smoked for months prior to that one time
February 4, 2016 @ 8:11 pm
You aren’t at a high risk of failing, with such light use.
February 3, 2016 @ 3:52 pm
Hey J, I havent smoked in the last 5 months, aug 6 was the last time. and took 1 dab on nov 22. I also took 2 hits of some good weed on jan 17th. Do you think i should be alright if my hair test is next week? My hair is about 1.5 inches and ill probably get it trimmed just a little bit this week. I have the zydot ultra clean and ill probably use that the day of. What do you think?
February 4, 2016 @ 8:07 pm
You have a good shot at passing, I think. That qualifies you as “light user”.
February 17, 2016 @ 11:09 am
I have to do a hair test next week for a high paying job. I haven’t had to take a drug test in 25 years. The last time I smoked was mid December. Before that it a few hits a few times a week on and off for a few months. I have been an on and off smoker since I was a teenager and I’m now 47. I often go years though not smoking. I just get that craving. I am a woman and have worn my hair VERY short for probably 15 years. My hair also grows very fast. I also cut it myself. I did pass a home urine test about 5 weeks ago as well. The hair on the top of my head is about 2 inches. I’m going to take it down to an inch today to let some growth come back. I seriously do not look like I’d smoke pot, gray hair and all. I’m just so freaking nervous about this that I can’t even sleep. Ugh. It feels so intrusive into my private life as well. I’m a masters educated professional and this just annoys me.
February 18, 2016 @ 4:33 pm
For the first time in 25 years I have to take a drug test next week and of course it is a hair test. I smoked 3-5 days a week on and off for a few months last year sometimes going weeks in between. Never a lot either. Maybe a very small bowl or just a few hits in the evenings and not every day. The last time I smoked was mid December and I was by no means a daily user at that . I passed a home drug test I took about 6 weeks ago. I have always worn my hair very short for a woman and am not afraid to go as short as it takes.The only thing they can even take a sample from is the top. I probably only have 60 days where I would test negative. That is all the hair I want to give them. I intervened with short hair, so it would be a question really if there was no enough for 90 days. My hair also grown really fast and at the length it is now, the only thing that could POSSIBLY test positive are the very ends. I will be absolutely humiliated if I do not not pass this and miss the opportunity of a lifetime. I ordered some shampoo to use the day of as well. I am hoping anything they find would be a low enough concentration to pass. I decided at my age, I am done smoking anyway. This stress is just not worth it.
February 20, 2016 @ 4:47 am
I took 2 doses of codeine cough syrup for a cold about 2 weeks ago, it was not my prescription. I have a follicle test next week and I’m freaking out! Do you think this will fail me?
February 21, 2016 @ 3:42 pm
No, I think you’re probably OK. Keep the bottle, just in case.
February 26, 2016 @ 5:47 am
Hello Jay Z. Would like to first thank you for all the information you have provided and all your hard work, time and effort you’ve put into this site; it is highly appreciated. Whether you’re in a jam or a friend, this is information that people should educate themselves with because the workforce has changed “Big” time! It’s hard to find selfless people as yourself, again, THANK YOU.
My question is, will a perm do the job. I am African American but I don’t do the pot thing; however curiosity revved his head up in late December and a couple of puffs I took. I have long thick hair, but don’t have money for Aloe Rid and those other two-no way! Get a perm and cut it. The jobs that I’ve applied for, at least two of them, test by hair. One has called-didn’t answer to nervous but I still have a chance with that one. Just wanted your take on my decision.
March 6, 2016 @ 3:20 pm
Thanks for your kind words 🙂
I don’t know if a perm would work or not. My guess is, no. I say this because I haven’t seen anything in testing industry / medical research or on weed boards that say it will.
Best of luck,
Concerned in LV
February 28, 2016 @ 1:06 am
Just moved to Vegas and had a wild “welcome to town” night on Thurs 2/22/16 that included several lines of cocaine. I don’t smoke weed, and this was my first go of cocaine. I wasn’t aware of hair testing, but being on the job hunt, am now worried I screwed myself for the next 3 months. I’ve read varying takes on the effects and subsequent testing results for single time users vs. regular users. Will I fail the tests for this one night of partying? I don’t have any hair testings scheduled, but can foresee there will be some in the near future as I’m applying for jobs. I keep my hair pretty short as it is, but it hasn’t yet been 5-7 days since I ingested, so from what I’m understanding, the drugs wont appear in my hair for another few days for me to even bother with shaving. Anyhow, sorry for the long winded question, but will this one time use be detectible starting in the next few days and consequently be haunting me for the next 90 days?
March 6, 2016 @ 3:16 pm
You are probably safe. The hair test is designed to detect regular users, not one-time users.
February 29, 2016 @ 3:59 pm
As of today February 29th is my last day of smoking marijuana (I hope) I haven’t smoked in maybe a few months since yesterday before then maybe 4 months ago I smoked a ounce and yesterday smoked maybe 4 grams. My job hires in temps within 3-5 months. I passed my urine test 2 weeks ago. And was told in orientation of my job that they have been hiring a lot and in 3-5 months I may be picked to be hired in. You can’t refuse to be hired in at least not from my knowledge because they will automatically think you’re dodging the hair drug test. I’m a black male 23 years of age and my hair is never 1.5 inches I don’t think I’ve ever let it grow out that far. I shave all chest hair, arm hair, and leg hair because I have tattoos in those areas so it makes it hard to see them if I’m hairy. The only places exposed to hair is my armpits and pubic area (which I tend to shave completely every so often when it grows to its maximum extent) the aloe option is pretty steep but I think I’ll go ahead and get that and maybe Macujo and Jerry G as well just to be on the safe side I’ll probably use some of the aloe in my last month then use the Macujo and Jerry G the next week, then use them both the day prior to when I have to take the test. If all works well or if I fail I’ll be back to post my results.
March 27, 2016 @ 7:36 pm
Hey I literally took 4 puffs of weed. But now I found out that I have to take a hair follicle drug test 12 days after. I’m not a smoker this was my first time in years. Will I pass the test?
April 3, 2016 @ 4:15 am
You’ll probably be OK. A single use is usually not detectable on a hair test.
April 5, 2016 @ 1:54 am
Would like some advice for a plan moving forward. I am a heavy user, 1-3g/daily for about 4 years with a few months off during those four years. My hair grows fast, but I am obese and I know THC stays in the systems of obese people longer.
I will have a hair test in about 5 months. My hair is currently very long and brown. I am willing to cut it, but not to 1.5 of an inch just yet.
What should I be doing? Especially because I have time to prepare. I’m just very worried that because I am overweight, THC will be in my system longer and therefore even harder for me to pass a test. In case it’s relevant, Caucasian female.
April 9, 2016 @ 8:46 pm
If you are Caucasian, then your hair probably grows about average.
So, if you abstain for 100 days and cut your hair to 1.5″ all around, you will eliminate any traces from your hair at the time of the test.
If you want to have longer hair at the time of testing, then add 30 days to the abstinence period For each 1/2″ of additional length.
Given that you are 5 months away from the test, your hair could be as long as 2.25″ all around at the time of the test.
April 5, 2016 @ 10:55 pm
I was just informed from a big company I applied for, that I gotta do a follicle drug test. So, i started researching online about THC in your system, & found this website to be very informative. I’m a stoner & prefer weed over any drug or alcohol. In Oct.’15 i had to stop smoking so i could pass any urine test thereafter, but passed my urine test using synthetic urine. In Jan.’16 i started smoking again everyday (about > an 3/8 of the finest i could get ahold of from a.m. – p.m.)til the first week of Mar.’16 because i was unemployed and i didn’t need to do any drug testing. So, as of Mar.’16 i have been clean. I backed out of my job offer because I knew that i wouldn’t pass my follicle drug test. I’m a clean cut guy who gets a haircut every week (1.5 on top w/ a razor fade or i simply shave my head with a razor). I also shave everyday, too. So I’m wondering if i will pass my follicle test or would waiting 100 days as you say is the best option. what levels of THC would i still hav if i am shaving my head from here on out to say 100 days of abstinence? what do u suggest or advise? help!!
April 9, 2016 @ 8:40 pm
Abstinence for 100 days, followed by a hair trim to 1.5″ is the most reliable method of passing.
That is the minimum amount of time to allow for 90 days’ worth of clean hair to grow back out, ready for sampling.
April 6, 2016 @ 3:28 pm
Hello. Thank you so much for all the help. The last time I smoked marijuana was exactly a week ago and before that I couple of puffs here and there. I don’t smoke marijuana but Just been going through alot and just wanted to hit it to ease my mind a Lil. Will I be OK to pass my hair test that’s just in a couple of days from now and if I was to buy a urine test and it says negative does that mean my hair test will come back negative as well?
April 9, 2016 @ 8:37 pm
You may be OK on the hair test, because a “few puffs here and there” is hard to detect. That said, you didn’t put any numbers behind your statement. Infrequent use = 1 to 3 times during the past 100 days.
The Urine test and the hair test don’t relate to each other, the way you may think.
A urine test detects traces of drugs that are in your blood stream, right now.
A hair test detects whether drugs were EVER in your blood at ANY time during the past 1 to 12 weeks (or longer).
Hope this helps. Best of luck!
January 11, 2018 @ 6:58 am
My 7 year old son who has obviously never used thc failed a hair follicle test. How is this possible?! He also is around light secondhand smoke rarely if ever.
January 13, 2018 @ 8:33 pm
That’s very strange. Second hand smoke does NOT register on a hair test. Is it possible he ingested edibles by accident?

Hey! So I am not a huge drug person. But I had back issues in January where I was given an iv of morphine to ease the pain. Then about 3 weeks ago I had slipped a disc in my back and was given another iv. What do I do? I am not sure they even sent me home with documents stating this.
April 24, 2016 @ 1:30 pm
By law, your hospital / doctor’s office has to keep records of all narcotics used on their premises. So ask them for a copy of your records.
Good luck on your test!

I’m applying for a position in my company, and they will do a hair follicle test. I have not done any edibles in a month. I’m not a smoker nor a frequent user. I’m just wondering if I would be ok, or should I wait the 3 months? I only did edibles on the weekend, and may 2 or 3 gummies during the week, and that was only maybe once or twice a week, not every day.
April 24, 2016 @ 1:24 pm
I’d wait for the 3 month to pass, just to be safe.
April 22, 2016 @ 8:45 am
So, I’m already bald… last time I took a hair test they cut it from my goatee…I’m going to shave that too….when it regrows I don’t know… if the test goes back 90 days… and that’s the most hair I have… when will I be safe?
April 24, 2016 @ 1:15 pm
Dear Mr. Clean 😉 ,
Regardless of where they clip your hair, you’ll need to stop using 100 days prior to your test to grow a sample that goes back 90 days.
For beard hair, the lab knows that facial hair grows more slowly than head hair, so they may accept a shorter length.
May 2, 2016 @ 4:26 pm
OK well, I just got back from test. It has been 4days since I stop smoking. I did macujo method 5-6 times I forget, blocked out the pain lol. I bleached and dyed it. Used the crazy aloe $200.00 shampoo and the zydot. Did some baking soda also and got my bathroom very humid. Will let you guys know.
May 4, 2016 @ 1:08 am
Great site by the way! It’s so hard to get a straight answer.
I have a hair test coming up and have been clean. I am prescribed to adderall. I was told that if I took some mdma that it would just show up as the adde. Is there any truth to this!
Thanks so much for your help
May 15, 2016 @ 6:07 pm
No! the test labs CAN tell the difference between MDMA/Ecstasy/Mollies and Adderall.
May 11, 2016 @ 1:46 am
abt two week days ago i smoked pot for the first ever, hardly a single hit, and had half of a caramel. i smoked again about ten days ago, just one hit. since i’m not a frequent user is it possible that these levels would not pass the threshold for a positive? the test will be in about a week.
May 15, 2016 @ 6:03 pm
You are probably safe. Hope this helps!
May 25, 2016 @ 5:52 am
In the charts what do you mean by cutoff level?
June 1, 2016 @ 4:55 pm
The ‘cutoff level’ is the minimum amount of drug traces (either a by-product/metabolite or the drug itself) found in your hair sample that defines a ‘positive test result’.
Cutoff Level is usually measured as a relative mass ratio, like “5 picograms were found per gram of sample”, or “5 pg” for short.
If drug traces found in your hair exceed the cutoff level, then you fail the test.
If drug traces are found in your hair, but are below the cutoff level, then you pass.
See chart above for cutoff levels for the most common drugs.
May 27, 2016 @ 5:45 pm
I’m bugging out about a hair test. Its for a really amazing job offer I had. I went today to get a physical. I passed the urine and mouth swab test like I knew I would. But I have pretty long hair. Its almost to my butt. I’m freaking out. The last time I smoked pot was 8/23/2014. Almost 2 years ago. I’ve dyed my hair 4 or 5 times since then. And have washed it almost everyday since then. Almost 2 years. This is an amazing job. And I used to smoke pot everyday. Do I have anything to worry about? I don’t smoke anymore and I don’t do any drugs at all and haven’t in almost 2 years. But I’m still worried… Should I be worried?
June 1, 2016 @ 4:48 pm
No, you should not be worried. They will clip a 90-day sample from your scalp, outward. Unless they’re trying to detect use 2 years ago (which I’ve never heard of), you should be safe.
May 29, 2016 @ 2:04 am
So, I love the site and the comments but found very little about those who are bald and no facial hair. So, I have smoked marijuauna in about 30 days. As previously stated I’m bald with no facial hair for the past 10 yrs. I do have arm, armpit, and leg hair. I’m not scheduled yet for a hair test for a job I recently interviewed for but it’s inevitable. This is a big opportunity and I don’t wanna miss out because of some old usage. By the time I take the test I’ll be at least 45-60 days clean. Should I shave my body hairs in anticipation of the test so that the new hair that will grow in by the time of the test is clean? Or should I wait, then detox and shampoo. Just trying to prepare because I think I’ll be getting the call pretty soon. Thanks for any help.
June 1, 2016 @ 4:46 pm
Hi Jay 🙂
In general, when faced with a bald head and clean face, hair drug test stations/labs prefer to sample hair from other locations above the waist. Often, that means arm pit hair.
There’s a chart above that shows how long drug traces remain in arm pit and arm hair.
To answer your question, if you’re a regular user, then yes, you should probably shave your body hair and try to reschedule if you can. If you cannot reschedule, then the Macujo and Jerry G methods are your next-best bet.
Hope this helps. Good luck on your test!
June 1, 2016 @ 12:41 am
I have not smoked for 6 months. I was a regular user prior to that (about 2 times per day) but like I said I quit in November. I started to work out and lost about 15-20 lbs. I’m 5’8 175lbs Caucasian male. Short black hair about 1inch long. I just took a psychemedics pre employment test first week of May. They took 1inch from 2-3 spots of my head. I got results 2 weeks after the test and they are saying I failed for thc-cooh with 1.2pg and 1pg was the cutoff. I lost a great job opportunity. I had no idea that I could have failed after six months of stopping. I didn’t believe the results and I scheduled my own hair test with my MD for next week. Can the lab make a mistake? Only thing I can think of is that my girlfriend smokes but never around me. We live together and could it be that she can contaminate my hair with her sebum/sweat? I told that to my preemployer Doctor and he said that is not possible. However I did read that some kids test positive for thc-cooh due to close contact with parent that smokes. I lost out on my dream job….. and I can’t have a retest. Hope this helps someone in same situation. What is your take on this J?
June 1, 2016 @ 4:31 pm
Thanks for sharing your experience, but damn, that’s sad to hear.
This kind of a false positive on a standard 90-day hair test is *really* rare. Did they test for longer than 90 days? What was the look-back period?
No, you won’t contaminate your hair (beyond the cutoff level) from another person’s second-hand smoke.
June 1, 2016 @ 1:03 pm
How are states that have legalized MMP( Medical Marijuana Licenses) treating the drug tests? For example, I’m in Michigan, I have my prescription card, but I don’t know how a potential employer would treat this circumstance. Any help you can provide would be great! Thank you
June 1, 2016 @ 4:27 pm
Great question! The sad reality is that employment drug testing is completely disconnected from the legalization of cannabis. One is employer’s choice, the other is voter’s choice. The laws that legalize use of a drug do not necessarily change how employers view use of that drug.
Even in Colorado, the state I live in, drug screening policies for cannabis remains pretty much intact at most businesses.
Basically, employers are free to do what they want right now.
Until legal cannabis states pass employment laws that mandate changes to employer testing policies, this situation probably won’t change very much.
June 15, 2016 @ 12:04 pm
I’m getting ready to attend CDL training and found that the trucking companies that pay for my schooling and licence training do both the urine test and hair test. I asked how far they go back on drug usage and they said 24 months. Not sure if this is DOT regulations or who but doesn’t matter if they’re telling the truth. From what I’ve read here that doesn’t sound likely but is it possible that they do go back that far? Hell, my hair is only a couple inches long! How would they do that with short hair? I quit yesterday to get clean for the urine test although I have something to help with that anyway but what would you recommend for the hair test. Not enough time to regrow enough hair if I shaved so I’m guessing the shampoo treatment but I’m wondering if I do the shampoo and have not used anymore but they put the test off for a month would I have to shampoo again before the test. In other words if I wait 8 days and then clean my hair with one of the above mentioned methods and used no more would I have to shampoo after that if they put it off? Not sure if they test before the training or before I start the job after training.
PS. I don’t seem to be able to get the links in this thread to go anywhere, keep getting 404’s.
June 26, 2016 @ 7:13 pm
They can only test as far back as your hair is long.
If your hair is 2″ long, then the test lab’s view is limited to the past 120 days or so.
If you are tight on time, and you believe your hair is tainted, then use the cleaning methods from a couple of days before the test up to the morning/evening before.
August 31, 2018 @ 4:22 pm
Did this work for you ?? I’m know someone of the SAME situation.
June 21, 2016 @ 6:43 pm
I have been clean for three weeks now, work out regular and drink a ton of water. Weight is 167 and height is 5 9″. I was wanting to know if when using Macujo method does it permanently clean your hair as long as you no longer smoke weed? If it does not it there a way to permanently clean your hair. I love smoking but the risks far out weigh the reward and I wanted to know if I am going to have to continue with the Macujo method for at least three months if I have a hair drug test coming up. I smoked around 1 joint or bowl a day for under a year.
June 26, 2016 @ 7:08 pm
All of the hair cleaning methods can only clean hair that has already grown through your scalp.
If you are tight on time and are sure your hair is tainted, then you should clean your hair right before your test (couple of days before up to day of), for best results.
June 26, 2016 @ 12:06 am
I really like all the info on this page. Your doing an awesome job!
Some pertain to me and some do not. So here is my instance… It has been a month and a half since I would take a 2 or 3 hits of bud once a day for about 3 months. Im bald (shave head and face once a week) and have plenty of body hair. I will be getting a job that does follicle tests in like August/ September. Will I be safe or should I do a hair clense for my body. I’m 260, I workout but not all the time (1 to 2 times a week) drink a lot of water just because Im a camel and take pills for heart hhealth that has antioxidants. My hair grows fast and of mixed background. Do I have anything to worry about. I can’t blow this. Once again thank you for all the info and helping all of us not be screwed over.
June 26, 2016 @ 6:56 pm
Given your frequent & recent use, your body hair will likely contain THC metabolites that will cause you to fail a hair test.
If I were you, I’d shave my body hair, today, and let it grow out until the test.
Your bloodstream is probably well below the limit by now, so new hair growing from this point forward should be free from THCOOH (THC metabolite).
Best of luck!
July 15, 2016 @ 6:27 am
I’ve read so many comments I should know all of the answers! I’m still not clear though, for us ladies with long hair, they will most likely cut the end off correct? Considering they won’t need the entire 10″ from scalp to end? So they will most likely be testing the hair from years ago not the most recent regrowth that shows I’ve been clean…I had a few hits maybe 3 months ago but I’m not exactly sure (could be a little less) I have had my hair bleached at the salon since but there is still hair that hasn’t been bleached in as well. I really don’t want to do anything crazy to my hair and most definitely will not be cutting it to 1.5 inches. Just not sure if I should apply knowing they do a hair sample. Also my female friends who work there are frequent users and dyed their hair right before and passed.
July 25, 2016 @ 9:40 pm
For a standard 90-day hair test, the hair sampling station is supposed to cut the sample out of the first 1.5″ of hair growth, from your scalp line outward.
If they do this correctly, they won’t send your entire length of hair to the lab for processing. So, older drug use can’t be detected.
That said, people with long hair are unfairly screwed by the hair test.
The problem is, of course: people.
Some samplers may or may not follow the cutting protocol correctly, so they may or may not send your older/tainted portions of hair along with the 1.5″ portion closest to your scalp. If they do send the entire length, the lab may test all of it, in which case you can fail for older use.
Your only sure bet is to cut your hair short, unfortunately.
October 25, 2017 @ 12:15 am
My questions is similar because I have very long hair. If I use the Mac method to cleanse my hair will it cleanse the whole length of the strands just in case the lab samples the whole strand rather than just 1.5 inches from the scalp?
October 28, 2017 @ 7:16 pm
It will clean all of your hair, if you run it through all of your hair. Works like any other shampoo.
July 19, 2016 @ 7:21 pm
Nice work and good info…thanks! I have a question. I was a regular THC user for a year. I have 43 days clean and I am starting to apply for jobs that probably require a hair test. I was going to cut all my body hair today. How long until I can pass a test? Should I give it another 60 days to let it grow out enough so I am not questioned? My hair grows rather quickly I think.
July 25, 2016 @ 9:26 pm
Mylo, I think you can shave now. Your blood levels are very likely below the threshold, now, so any hair that grows will be clean.
July 20, 2016 @ 7:22 pm
First off let me say thank you for this website and all the help you have given people. I have the drug screen coming up as well, I am not an avid smoker. I believe in this whole year I have done it 2 times, I know for sure I haven’t done it in the following months, July, June,May, and I believe April. I’m a black male and my preferred choice of hairstyle is like a low fade so I usually have less than 0.2 in. I know for a fact that I have cut my hair multiple times since April, and I have started growing my hair (since June) to make the 1 in mark within the next week. Would I still need to try to strip my hair with the Macujo method or the Aloe product or do you think it’s a good possibility I’ll pass? I’m pretty confident that I’ll pass based on the stuff I have read on this website and some other research I have done, but just wanted a final opinion. Thanks for all your help by the way.
July 25, 2016 @ 9:18 pm
Honestly, you are a very light smoker – so you should pass with no problem. No need for treatment, in my opinion.
Let us know how it turns out!
August 5, 2016 @ 6:06 am
Yes, please let us know for the light smoker to very light smoker…
July 23, 2016 @ 10:20 am
I used older clean on my head and my armpits my hair wasn’t long enough so I took it from my armpits and I failed
July 25, 2016 @ 5:36 pm
I have a shaven head. I had 5 bottles of wine over a 3 day period 19 days ago, My ex has now asked for a hair sample test. Will this show up on the test when my hair grows a bit and can they test other hairs on leg or chest for example.
July 25, 2016 @ 9:10 pm
Yes, very likely it will show.
August 4, 2016 @ 5:35 pm
I passed my test. They took it from my body because my head hair was too short. I shaved my chest 2 weeks prior and trimmed my arm hair down the night before(just under half and inch). I had used cocaine 3 times within 3 months. Last time being 40 days before the test. Hope this helps anyone out there. Oh yeah they did take it from my chest and arms. I was surprised they used my chest hair because it was less than half an inch as well.
August 6, 2016 @ 10:35 am
Okay, here’s my story. Was clean for nearly 2 years and then a friend gave me a gift which I used over about a month. Been about 90 days now (first week of May) and yep, GREAT job offer pending the regular background check and drug test. I’m on a pain management program and know my urine is clean cause they test on a regular basis and I passed about 5 weeks ago. I’m thinking it’s going to be a hair test for the new job and here’s the kicker, I keep my hair very short (usually <1/4") and am clean all over for my wife so the only hair besides the head hair (should be clean by this time for sure) is my eyebrows that might not be clean. Hair is currently about 1/4" and I'm leaving it alone until this is all over. I'm getting 'old man – bushy' eyebrows so they are trimmed but still worried. Eyebrows are getting the Nexxus treatment as soon as it gets here! I'm hoping all the freaking out is for naught and they hand me a cup but only time will tell.
August 14, 2016 @ 4:54 am
Thanks for replying to my previous post I appreciate it.
I haven’t taken the test yet being due to my hair being too short and I’m waiting for it to grow out. My question is, I just had a drink that I made for myself at home, and I wasn’t trying to get drunk or anything but I used about 2 tablespoons ( 1 US ounce) of a liqueur (40% alcohol) for the drink. I forgot I have the hair follicle test in the near future.
Would it be possible for it to show up on the test (30 day test) ? Does the hair follicle test for alcohol just detect if there was any alcohol in the system? I don’t think it would detect it because of the amount, but just asking to have a second opinion.
August 15, 2016 @ 10:37 pm
If that’s all you had to drink, 1oz of 80 proof liquor, then no, I don’t think you will fail the test.
August 31, 2016 @ 2:24 am
This maybe a very dumb question, and im just a dumb welder, but back in January, i had to take my little daughter to the Dr. Because her mother kept giving her to my with head lice, i would clean her then send her back and the cycle kept happening, ANYWAY back to the question. From the experience i had with cleaning lice not only from my daughter’s head but to insure there wasn’t going to be a chance of her getting it from my place i did the whole house and treated myself. Do you think the RID-X could work on a hair follicle test?
September 8, 2016 @ 10:24 pm
There are no dumb questions, John.
But, no, I’ve seen no evidence that Rid-X has any effect on a hair test.
Worse, it could be dangerous to put it on your head (not that you said this), because Rid-X contains a poison that can be absorbed through your skin.
August 31, 2016 @ 10:22 pm
Hello jay! Thanks for all the info. I have a hair test coming up I am not a smoker by any means (I don’t like to get high) but for medical purposes I was taking pure cbd oil 300mg up until 2 months ago i would take by mouth 2ice a day. Recently when I found out I’d be tested for a job I checked the bottle and it also contains 15mg of thc. I’m wondering if this will show up on my test ? I havent seen a question like mine so I though I’d ask thanks!
September 8, 2016 @ 10:21 pm
Yes, it is possible your CBD oil will cause you to test positive for THC.
Bring a copy of your medical script/prescription with you to the test that shows the mg of THC in the oil & recommended dosage, so they can factor this into their analysis.
September 3, 2016 @ 1:30 am
Here is my story, I think I am pretty close to beating this thing…
Found out I had a test August 1st, quit smoking august 2nd.. puts me at 31 days clean or better worded a month.
History: Frequent user for the last 4-5 years, caucasion, 6′ tall, active
Hair: Short (prob 2 inches) brown hair
Just recently got my hair lab test I sent in back and I’m at 1.85 pg/mg (really wish i would have figured this number out initially in early august, but is what it is)
What I’ve done: Bought the Nexxus Aloe Rid and have been using that for the last month. During days 15-22 I did the Maccujo therapy every night using vinegar, clear & clear, nexus shampoo, & tide at the end.
My main question is, how close in reality am I to getting this down .85 in the next week? Is that a big number? I’ve seen some other posts where people were initially at like 17 pg/mg , 34 pg/mg before starting any treatments. Kinda trying to guesstimate maybe where I was before I started and actually what has worked the best in lowering my pg/mg.
September 8, 2016 @ 10:08 pm
I am not aware of any reliable scientific data about the Macujo regimen that would help you predict a reduction in TCH-COOH concentrations this precisely. If anyone else has this data, please share!
September 8, 2016 @ 12:22 am
Most of the comments have been helpful, however i havent seen anyone in my exact situation. I used to be an everyday smoker for years. Several blunts everyday. I applied for my dream job and was hired with the stipulation i had to pass a hair drug test. I immediately quit smoking weed. I havent smoked now for 140 days. My test is coming up in a week. Do i have anything to worry about? Should i still do a detox shampoo or the jerry g method?
September 8, 2016 @ 9:54 pm
I think you’ll be fine, as long as your hair is 2″ or shorter, all around.
All the best, on your test!
September 8, 2016 @ 4:45 am
The first time I smoke was early July and I have probably smoked 4 times since then. Each time only a few hits and never actually getting high. These were not frequent and the last one was probably two weeks ago. What are my chances of passing a hair test next week?
September 8, 2016 @ 9:38 pm
Your chances of passing are excellent. That’s probably not enough use to register on a hair test.
Best of luck!
October 13, 2016 @ 3:17 am
First tried cocaine about 2months ago and very little amount but cut my hair every other week.. Would it show up if I test in 3 weeks?
October 21, 2016 @ 8:04 pm
Seriously doubt it.
Best of luck!
October 14, 2016 @ 2:11 am
My son’s father is an addict, unfortunately. I just found out last week that he has relapsed and has been smoking crack on/off for the last 4 months. Over the last 4 weeks it became debilitating to the point he had to take a LOA from work because he wasn’t able to function. (He has been known to smoke around the clock for many days at a time). This has been a 7 year battle and he has had almost 3 years clean prior to this June. We have a 7 year old son and I am taking dad to court on Oct 25th. On this day he will have to take a mandatory drug test (hair) by 5pm. With the amount in his system – even though he “may” have a 2.5 week gap where he stopped using – is there ANY chance he will test negative even if he goes through the methods listed above?? My son’s safety is at risk at this point and I don’t want his dad to have him in his possession until he can prove sobriety. Please help me better understand this process around trying to trick the system for a hair follicle test.
October 21, 2016 @ 8:01 pm
I can’t see how he would pass a hair test, given the facts as you outlined them (smoking so much he can’t work, etc.)
Good luck, to you and your son.
October 14, 2016 @ 5:54 pm
I’m diagnosed worth add/adhd and have been prescribed the non-narcotic treatment which has failed to help my condition. My nephew also has the same condition and has recently had his prescription changed and so for about a week, I’ve been using his old unused Ritalin which has been a great help with my condition, but stopped a couple of days ago. I also took a couple drags of Marijuana once about a month ago and the same about 3 months ago. What are the chances of these showing up on the follicle test?
October 21, 2016 @ 7:59 pm
Marijuana: very low/minimal risk of detection.
Ritalin: depends on how much you’ve been taking. If @ prescription level or higher, then yeah, sorry to tell you: it’s probably going to show up.
October 15, 2016 @ 3:37 am
I last smoked half a joint on August 10th. Before that I smoked probably a gram over the course of two weeks. I am getting tested within the month, should I be worried?
October 21, 2016 @ 7:58 pm
No, I wouldn’t be too worried. That’s pretty light use.
i dont see my comment
October 20, 2016 @ 3:46 pm
im a heavy smoker the last time i smoke was 30 days ago i got my test in 10 day i cut my hair yesterday is how likely is it for me to pass
October 21, 2016 @ 7:50 pm
I don’t think you will pass. You need more time – at least 100 days from last use to grow 1.5″ of clean hair.
Sorry for the bad news 🙁
October 20, 2016 @ 7:23 pm
Hello JZ, and thank you for all the dedication you put into this guide, you are really helpful. Reading through some of the comments I see that you answer almost to all of them! and I am really impressed, thank you very much.
I have a problem in determining if I need to do Macujo/Growman method since I suffer from dermatitis on my scalp. I recently applied for a job and was silly enough to think they would ask for a urine test rather than a hair drug test. I really want this job, and I am facing a hair drug test in around 40-60 days, here is my info of usage:
Frequency: Maximum 4 times per weekend for 5 months. (I would say like 2 grams per month, +-1gram)
Smoked Hydro, like 2 bowls per session.
Last time: 10/15/16
140 lbs – 5’9″ – Fast metabolism – In my 20s . (in case of a urine test)
Extra note: As of today, I have passed a urine test done by a FDA approved home test kit. (That will be a negative result just after 5 days I stopped smoking)
I have stoped smoking, obviously, and I am really scared lol. I am still not sure if the THC traces that I have from October will show up for a hair test in December… I mean, I would say that I am a light user by the facts that I have stated above, what do you think man? Do you advice me to still do the Macujo/Grownman, just the Detox Shampoo, or do nothing? which I don’t really think so. I’m not sure if you read it all, if you did BIG THANKS, hope you can help me JZ.
October 21, 2016 @ 7:48 pm
I see your dilemma.
It’s not possible for me to tell you with great certainty what to do, other than to err on the safe side and recommend the Macujo.
It’s a lot less harsh on your scalp than the Jerry G method, by a mile.
October 21, 2016 @ 1:22 pm
If I smoked the same day I go take a hair follicle will i be ok? I am gonna use zydot ultra clean.
October 21, 2016 @ 7:46 pm
If you haven’t used anything in the past 100 days, then yes. Otherwise, you’re taking a chance.
October 21, 2016 @ 5:43 pm
So I am a heavy smoker, and have a great job opportunity that requires a hair follicle test. So I shave my head because I am balding, but I have a beard. Would they use my facial hair since it’s over 1.5″? And what options do I have since I have no hair on my head?
October 21, 2016 @ 7:45 pm
They will probably take a sample from your beard, unless you shave it.

October 28, 2016 @ 2:49 am
I’ve been clean of any drugs for 109 days will I pass the hair folicile test?
November 12, 2016 @ 4:37 pm
That depends on what drug and how heavy a user you were.
If very light user, and NOT marijuana, then yes, you will probably pass.
If you are a heavy THC user, then there’s a chance you won’t pass, because THC levels remain high in your blood (and entering your hair follicle) for far longer than w/ other drugs.

I just took a hair test Nov 1st, haven’t smoked since roughly May 17th which is about 170 days. I am a female with long hair..Do u think I will be able to pass? I am totally panicking this is for a great job
November 12, 2016 @ 4:24 pm
If the sample station techs did their job correctly, then yes, you should pass.
If you get a positive hit / fail, then I would challenge the length of hair that was sampled. Many employers won’t retest you, because what they really want is someone who doesn’t use, at all. But it’s worth a shot.
November 7, 2016 @ 2:49 am
Jay Z, Thanks so much for all of the information you have provided for us. About 57 days ago I encountered coke for the first time. I put 2 small amounts of it on the tip of my finger and rubbed it on my gums. How likely will it show up on my hair test? I am a woman who has long hair, but I have never done drugs before. So upset that I put myself in this situation. Do I need to do the home remedies? Please help me!
November 12, 2016 @ 4:15 pm
No, I don’t think you will test positive for cocaine. That’s a tiny amount for a hair test to detect.
November 9, 2016 @ 10:29 pm
Hey jay, i took 30 mg of Gummi es 109 days ago. I just had to take a hair follicle test. They took two inches of hair do you think I’m ok? That was my first use in over a year.
November 12, 2016 @ 4:08 pm
Yes I think you will be OK.
November 12, 2016 @ 4:26 pm
Clean your hair vigorously, using the Macujo (Aloe Rid) or Jerry G (bleaching) method. And pray.
Wishing you all possible good luck 😉
November 18, 2016 @ 10:27 am
Firstly, thanks so much for all of your help on this site.
I’ve got a hair test in January, and went to Amsterdam last weekend. Before that I hadn’t smoked since about 8 years ago where I was quite a regular smoker.
Last weekend we had about 2g shared between 4 of us. The test is for my dream job that I never thought I would even get an interview for where they have a zero drugs policy, and by the time the test comes, I’ll be around the 73 day mark (if they’re going by the 90 days).
I’ve got quite long hair that grows pretty quickly – do you think I should get hold of some Aloe rid? It’s quite hard (and expensive) to get hold of, especially from the UK, but I’m willing to if needs must!
November 22, 2016 @ 10:37 pm
Save your money – chances are you will pass, if that’s all you’ve done in the past 8 years.
Best of luck,
November 18, 2016 @ 9:25 pm
Hey Jay I used to smoke everyday but u quit about a month ago. I have a big job opportunity but they hair test, if I get a haircut now and wait 3 months will I pass?
November 19, 2016 @ 10:33 pm
Yes, Carlos, you should pass if you wait another 3 months (total of 4 months without using).
To make sure no older/dirty hair gets sampled, cut your hair to 1.5″ or less all around by the day of the test.
November 21, 2016 @ 2:08 am
ok.. I smoked some bud back around the may or june time frame. 5-7 pulls that’s been pretty much it. get hair cuts on the regular. And shaved then regrown my beard since then. Should be worried? it’ll be 6 to 7 months since I last smoke.
November 22, 2016 @ 10:30 pm
You should test clean!
November 22, 2016 @ 7:22 am
If my blood is clean and I cut my hair and let it grow back out would my hair be clean?
November 23, 2016 @ 10:27 pm
After your blood tests clean, you will need to wait 7-10 days so the remaining unclean hair can grow through your scalp line.
THEN cut your hair.
December 11, 2016 @ 3:59 pm
When do they ask you for a hair test? I mean its like all urine tests right? I haven’t heard about somebody that would have to go for a hair drug test. Anyway, is it true that they only take 1.5 inches as stated in the hair follicle drug test? You know, cause thats only 3 months so if you smoked half a year ago, it won’t show up. Right?
December 15, 2016 @ 11:12 pm
December 12, 2016 @ 6:48 am
Just curious if u have any insight on my situation. I’m trying to get a job well I already got offered the job just pending a hair follicle test. I haven’t smoked in 2 months. I wasn’t a heavy smoker but I smoked about a gram a day. I shave my head every week and my hair grows about a 1/4 inch a week. I went yesterday to do the test cause I have a goatee but the lab said it wasn’t long enough for the rest. I don’t have any other body hair so they checked my finger nails to see if they were long enough for a finger nail test. But I keep them short cause of my infant daughter. So they told me to come back when my hair grows out. Do u think I should be good on the hair follicle test or do I need to do some treatments. I know I can pass a urine test. Just passed one two weeks ago for court to see my daughter.
Thanks in advance
December 15, 2016 @ 11:11 pm
It’s hard to say, because I don’t know when you last shaved your beard down to the skin.
Given your history of use, in order to test clean w/ beard hair, you should have shaved all facial hair off about 2 weeks-1 month AFTER you stopped using. This is about when the first strands of clean facial hair would have started growing through your skin.
From that point, you’ll need to grow enough clean hair to the length they ask for, which is typically 3 months’ worth.
Ask your employer/test lab how much hair they need to sample (length); then, tell them you think you’ll need 2-3 months to grow that much. Whatever you do, don’t tell them that your hair grows FASTER than normal (which it does), or they will try to make you come in too soon.
Best of luck!
December 12, 2016 @ 6:42 pm
Does it take longer for thc to get out of your hair if you take dabs of thc oil instead of smoking tree? Im a daily dabber and was thinking of taking around 5/6 months off before taking a hair test, thoughts??
December 15, 2016 @ 11:02 pm
No difference between oil and plant.
After THC gets into your bloodstream, it’s all the same from there.
January 4, 2017 @ 10:35 pm
I take adipex and Adderall here and there what are the odds of those coming up in a hair test?
January 6, 2017 @ 5:03 pm
The odds are good they will be detected. Adderall is an amphetamine.
January 16, 2017 @ 12:21 pm
Where do you buy a hair drug test at? And how do you pass after snorting meth?
January 22, 2017 @ 4:42 pm
See the table of drug tests, above. You can find them on Amazon (confidential), Walmart and most local drug stores.
January 18, 2017 @ 12:37 am
I have really long hair i been clean for 104 days do you think i have a good chance in passing a hair test.and also are u able to ask for them to cut off the hair that isnt needed for the the 2 in test.
January 20, 2017 @ 4:40 pm
Good question. This is a tricky situation, due to the way the real world works.
IF the technician does his/her job correctly, then they should only snip about 1.5″ (or 2″ in your case) of hair *from the scalp outward* – and discard the rest.
1. some techs don’t follow procedure, and clip a longer-than-expected sample.
2. the lab techs may not know which end is which when they receive a longer-than-expected sample; so, they may end up testing the whole sample
I don’t have any data on how frequently mistakes like this are made, but real-world experience tells me not that uncommon.
Wish I could give you better news, but that’s what I know.
January 23, 2017 @ 7:54 pm
Hair follicle test coming up mid to late April. I smoked (not by myself) about 0.2gm, 0.4gm, and 0.3gm of meth on three separate occasions over the last 2 weeks. I do not intend to smoke from here on out, which could put me at just about a week short of 90 days. I will only be tested for use since mid January. What are your thoughts on the chances of passing without any kind tricks? I’ve been curious as to whether boosting hair growth rate by taking something like prenatal vitamins or other supplements that claim to increase the rate of hair growth might push my recent use past the 1.5 inches of hair to be used for testing.
January 25, 2017 @ 4:32 pm
You are cutting it really close. If it were me (and I’m a guy, so), I’d cut my hair to 1″ length, all over my head right before the test… to see if they will accept a shorter length for the test.
January 30, 2017 @ 8:05 pm
I never use. I took my first edibles at Thanksgiving and smoked only once at Christmas. I am now looking for work and may have a an impeding hair test coming up. Given that I’m not a “regular” user, how likely is it 50 ng/ml show up? My hair is short on the sides and a little longer on the top.
February 2, 2017 @ 4:27 pm
That’s not much use. I seriously doubt you will test positive.
Edibles tend to take a long time to metabolize in your body, and remain at very low trace levels throughout that time. One prior smoke won’t register.
February 1, 2017 @ 3:01 am
I had a hair follicle test today and i afraid its going to come out positive since i tried cocaine 2 1/2 months ago it was just a one time use, i just wanted to know what are the chances of coming out positive..
February 2, 2017 @ 4:25 pm
Actually, your chances of testing positive are very LOW. Please let us know how it turns out!
Best of luck,
March 8, 2017 @ 4:23 pm
I was wondering how your drug test turned out. I did the exact same thing and will be taking the drug test soon
February 23, 2017 @ 1:12 am
I took “one” hydrocodone 10-325 about 2 or 3 months ago for a toothache. Only time ever taking it in my life. I have a hair follicle test in a week. Should i be ok? Thanks
February 24, 2017 @ 4:56 pm
Bring your receipt and your prescription to the test. Keep a copy for yourself.
March 6, 2017 @ 8:35 pm
I have been arrested for Marijuana and have been taking urine drug test. I now have a Hair follicle test coming up. Does alcohol show up on the same test or is it a separate kind of hair test that they take?
March 7, 2017 @ 4:45 pm
It really depends on the specific test ordered for you. If you have a court order banning you from alcohol, then yes, I’d assume they will test you for it. It’s not a different kind of hair test.
March 13, 2017 @ 10:59 pm
Hey Jay, I just responded to a job offer I was really excited about, until they told me about the hair follicle test and I panicked. I used MDMA the first week of January and haven’t touched it since. I was a heavy smoker for probably 8 months, stopped, but smoked very lightly about a week ago. If I did the MacCujo method, would this work or am I just out of luck for getting the MDMA out of my hair? I have fine dirty blond hair. I’m extremely nervous and could use some advice! The drug test is coming up soon, I don’t have a date yet, but I’m hoping to push it to April. Any advice or further information would be amazing!
March 14, 2017 @ 4:28 pm
My main concern is not your MDMA use (one dose probably won’t show up in your hair). I’m far more concerned about when, exactly, you stopped smoking.
If you stopped completely 5+ months before your test, and only used once since, then you’ll probably pass a standard 90-day hair test.
If, on the other hand, you stopped using just a few weeks ago after 8 mos of heavy use, then you are at very high risk of failing; so, you need to consider a cleaning regimen (see details on this page: https://hairfollicledrugtest.info/thc-detox-clean-hair-home-remedies/)
Hope this helps. Best of luck!
March 31, 2017 @ 8:59 pm
Haven’t smoked in at least 7 years… used to smoke somewhat regularly only small amounts 1-4 times a week for 10-20 years would all my hair be clean after 7 years I haven’t had it cut in ages?
April 2, 2017 @ 5:57 pm
You should be fine. When a hair test sample is taken from your head, the sample is supposed to be cut from your scalp outward – the youngest hair. If the lab does their job correctly, you’re more than safe.
April 10, 2017 @ 1:13 am
Hi jay z,
Thanks for all the info. Awesome site!
My situation is I did 1 gram of coke on 12 feb(nothing for a year before that) have the hair test on the 26th April. So about 73 days clean. I’ve already shaved all my body hair two weeks ago which is growing back nicely. Was going to get my head hair cut to one inch the night before. Assuming they still do the test….should I be clean? One inch of hair will only test the last two months right?
April 11, 2017 @ 5:45 pm
That’s correct: 1 inch = 60 days of growth.
April 11, 2017 @ 3:32 am
I’m a heavy raver and sort of frequent user of MDMA/Molly. I started raving and taking these drugs in May of 2016. I started out with 1/4th, and have upped it to a half now. I rave a maximum of twice and month since then. I have super long hair (barely touching my butt and I’m 5’7) and don’t want to bleach something I’ve taken time to grow. My parents recently found out I smoked weed (which i do, but not as often as Molly. Only smoked a total of like 6-7 times since May 2016 and only take a few hits). My last time was January 12th of this year. I have a major festival to attend in about a little over a week where I plan to roll every day, taking a whole pill each day. My parents said they will be hair testing me when I get back, and I’m super nervous because they only the tip of the iceberg (smoking, not pills). If they find out, they won’t let me out of the house, as I have incredibly strict parents. What is the best method to strip all of these drugs from my hair? Please help. Thank you!
April 12, 2017 @ 5:43 pm
Your best method for stripping hair – aside from abstaining for 100+ days – is to try one of the two methods detailed on this page: https://hairfollicledrugtest.info/thc-detox-clean-hair-home-remedies/
Good luck, Raver 😉
April 11, 2017 @ 8:22 pm
I need to take a hair test to clear my name. Its been 45 days since I’ve used meth and smoked weed. Before I had only been using meth for maybe 3 months not everyday but often I would say. Wasn’t an everyday weed smoker but I would out of a weeks time probably 3 times. Does the 2 methods work on all types hair? I’m just very curious about these methods. Thank you
April 12, 2017 @ 5:41 pm
Yes, these methods work on any type of hair.
April 14, 2017 @ 12:29 am
I had a hair sample test on Wednesday’s unknowing this would be that kind of test for emoloyement. I was not given a heads up. I ate 2 hard candy edibles middle of February and smoked a joint 20 days ago. That is all the use I have done. I have blonde hair shoulder length. Will I test positive?
April 14, 2017 @ 5:39 pm
You’ll probably be OK. Wishing you luck…
May 1, 2017 @ 8:43 am
hello jay z. if you last did some bam bam in late February and took a puff of MJ in late March then shaved head to toe in early april. Would you have to worry about a hair follicle test ? I don’t have a 1.5 sample anywhere on my body but then again I never have because I keep my hair shaved anyways.
May 1, 2017 @ 4:23 pm
With that little use, yeah, you’re probably safe if you shaved 2-3 weeks after your last hit. If it was closer than 2 weeks, then you should probably take another 1/4″ off the top.
May 1, 2017 @ 4:36 pm
I used to smoke pot fairly infrequently. I used smoke small amounts a couple times a month, with fairly long periods clean between. This only went on for about 1-2 years and as far as I can remember, the last time I smoked pot was the beginning of 2016, maybe February (Worst case).
I’ve not touched the stuff ever since, and since I last used it, I’ve had my hair cut probably 10+ times. I did a home Urine Test a couple of weeks ago and passed.
My test is on the 18th of May 2017, do you think I’ll pass?
May 1, 2017 @ 11:24 pm
Yes, I’d be surprised if you failed. Let us know how it turned out!
May 2, 2017 @ 1:53 am
Would passing a hair test be harder if I use iv to do my drugs?
May 4, 2017 @ 4:13 pm
HOW you put drugs into your blood doesn’t make a difference. HOW MUCH gets into your bloodstream, is what matters.
May 6, 2017 @ 12:55 am
Best forum for some peace of mind, thank you Jay. Let me get your opinion.. I have done some pills and and cocaine around January-February 2017. Super light usage. About a total of 2 grams of coke in a month period and about 5 adderall pills and maybe like 5 xanax pills. I shaved my head around February 20th or so after stopping those three things 2 weeks prior. I am a regular smoker of MJ but the last 6 months its been super light usage like literally a bowl at night before I go to bed. I’m sure the pills and coke are out because I shaved my head…. But. my hair grew back out to about 2 inches and in between that time Ive taken 1 xanax pill and about 6 or 7 Oxycodone 10mg in about a 2 month period. I just again last night trimmed my hair about 3/4″ just to take care of some of the contaminated hair. I need to have hair for a possible hair test in a couple weeks. my hair should be at 1.5 ” or more in a couple weeks. So pretty much from Feb. 20th(when i shaved my hair) until yesterday(5-2-17) before I trimmed my hair, I have had 6 or 7 pain pills(10mg), 1 xanax and I smoke like 2 bowls every other night. I’ve tried Zydot shampoo in the past and failed. At that time I was taking pain pills regularly and never stopped before the hair test and I was smoking weed kinda heavy everyday. I only failed for the pills, they never mentioned anything about the MJ. Since I have had light usage, do you think zydot shampoo will work better for me? Thank you
May 6, 2017 @ 8:06 pm
Honestly, you are at high risk of failing your upcoming test, given your recent use.
If I were you, I’d try to delay for a few months and stay completely clean; if you can’t do that, then I’d use more than Zydot to strip your hair. Full Macujo or Jerry G is a better option.
May 6, 2017 @ 10:01 pm
I’ve got a hair drug test on the 30th of May. I used to smoke weed every now and then, tops 5 times in any month with periods of one to two months clean in between. This went on for 1 or 2 years. The last time I smoked was (I think) February 2016.
I took a urine drug test a few weeks ago and passed, do you think I’ll pass the hair test?
May 7, 2017 @ 4:02 pm
It’s possible you will pass (esp. if you cut your hair down to 1″ or less all around), but your test would need to be at the end of June or early July – at the earliest – for me to say this with confidence.
Hoping for the best!
May 9, 2017 @ 9:39 pm
Hey there. I took a hair follicle test today 8 days after about 5-6 small lines of coke. I see you saying it takes about 5-7 days for tainted hair to grow above scalp line, but I want to know how solid that info actually is? I see in other forums/websites people saying its 7-10 days and in some cases 7-12. Any thoughts?
May 10, 2017 @ 3:56 pm
Yes, 5-7 days is typical for the average human scalp.
NEED HELP, FOLLICLE TEST COMING SOON
May 16, 2017 @ 12:05 am
I need some advice.
I’ve been smoking really regularly since January (at certain points, it was every day). I’ve not once gotten caught until now; I’ll leave the details out since they’re irrelevant. However, I told my parents that I smoked one time and it’s never again (I got high and pretended I was just sick that morning; not how I got caught, but again, that’s irrelevant). However, I forgot to clean up all the way and my mom found my pipe. They now suspect the truth, and my mom says I’m getting a follicle test in a month (exactly one month). I don’t know if i can do any of the things listed here (with an exception, which I’ll elaborate on in a sec).
How specific is the test? Will it only tell them that I *have* smoked within the specified time (my hair is about seven inches), or will it tell them that I smoked heavily for the past five months? Also, though the other shampoos are less reliable, how likely am I to be clean if I use them every single day for a couple weeks?
May 17, 2017 @ 3:23 pm
Sorry to hear about your issue. Lots of us have been there 😉
The test does not reveal WHEN you used, just IF – and, sometimes, HOW MUCH.
If your test results reveal HOW MUCH metabolite was in your hair, and the traces are high enough, then the lab can infer whether you are a heavy user or not.
Also, if your parents do a little research online they can probably figure out the same thing, just by reading the results.
Best of luck!
May 19, 2017 @ 5:57 pm
I see lots of comments about THC. But wondered about H. If literally a few hits of H were smoked about 3 months ago, will that show up on hair strand test in 2 weeks? No drug use for over two years, aside from this little slip of a few hits in one day. Is this testing used specifically to see chronic or continued use? Or will a little slip show up in the testing window? Thank you for your input!
May 20, 2017 @ 3:15 pm
All drugs work basically the same way, for the hair test.
Once metabolites / drug traces enter your hair follicle through your bloodstream, they remain in your hair as a permanent record.
After that, you need ~100-120 days (depending on the drug & amount used) of abstinence to grow enough clean hair to pass a 90-day hair drug test.
Works the same way, regardless of drug. Thanks for asking this.
May 19, 2017 @ 11:28 pm
This may have been answered but there are many comments, so I wanted to confirm something.
Swim stopped smoking weed 3 weeks ago. Swim tested negative on 3 at-home drug tests claiming 99% accuracy 10 days ago. If swim were to shave his body/head 11 days after taking the at home drug tests, would Swim’s hair be clean?
May 20, 2017 @ 3:11 pm
Depends on the type of ‘home drug test’ you’re talking about.
If you used at-home HAIR drug tests (sent to a lab), then, yes, you’re probably clean if you haven’t used since.
If you used URINE or SALIVA tests, however, then NO – this does NOT mean your hair is clean.
You need at least 100-120 days of abstinence to grow enough clean hair for a standard 90-day hair test.
The only way to ensure your hair is clean is to take a HAIR drug test.
See list above for reliable at-home hair tests you can buy online.
May 24, 2017 @ 2:07 am
Hey Jay – Great site and many thanks!
Clean of Pot for over a year…then: Mid Oct 4-5 hits off a bowl, Christmas 3-4 hits off a bowl, Feb 2-3 hits, May last week: 6-7 hits of a joint (not very big hits), 2 days later 2 hits, and 2 days later another 2 hits.
Chances of it being reaching blood to follicles? Chances of failing? Thanks!
Mary Ann Lyons
May 27, 2017 @ 4:07 pm
If I did crystal one day a week like 3x will it show in my hair test?
May 28, 2017 @ 2:58 pm
Yes, it’s possible.
July 14, 2017 @ 2:53 pm
Did it show up
June 2, 2017 @ 3:16 am
I been 15 yrs clean 7 weeks ago fell off the wagon and done 2 lines of meth. What’s my chances of passing a hair test?
June 6, 2017 @ 2:48 pm
I think there’s a good chance you’ll pass.
FWIW, I HATE to hear stories like yours… the test is so damn unfair for people who’ve quit and then slip up, just once.
Let us know how it turns out. Good luck!
June 11, 2017 @ 11:28 pm
Hey Jay. I smoked for about a month and half over a month ago. I only smoked a little on the weekends ( not heavy all week) and nothing for years prior. What do you think about passing a hair test in another week? 6-7 weeks after the last time?
June 13, 2017 @ 2:37 pm
You have a good chance of failing, is my best guess.
Using more than 1-2 times over the past 100 days technically puts you at risk for failing a hair test.
June 18, 2017 @ 3:25 am
So what did you actually use I might have a hair test soon and shitting bricks
Mr.not so clean
June 29, 2017 @ 5:38 pm
Thank you for all of the great advice. That’s really awesome you take the time to help people out. I just wanted to get your honest opinion on my situation. I’m applying for a good job and of course have to take hair follicle test. I quit smoking weed April 25th and was a regular user about a gram a day for a good 8 months. My hair was kinda long around 6 or 7 inches around June 20th I got it cut to 3 or 4 inches. After I quit smoking I exercised a good amount and drank tons of water and cranberry concentrate. I had a slip up and hit a bowl 1 time on June 17th then did 4-5 lines of coke on June 18th. The day before my test I soaked my hair in baking soda then detergent then acidic face wash then vinegar all for 30 minutes a piece after that a couple hours passed then I bleached my hair for 30 minutes. Then next day (june28th) i dyed my hair back to original color waited couple hours then used a detox shampoo called maximum strength ultimate gold biowash from head shop cost 25$. After following steps from shampoo I went and took my hair follicle test. My girlfriend convinced me to reverse the home remedy steps. What is your opinion on if I will fail or pass? I really wish I would of found this sit before hand.
Quit smoke April 25th
Hit weed once June 17th
did 4-5 lines coke June 18th
Cut hair to 3-4 inches June 20th
did home remedy and bleached June 27th
dyed hair back then detox shampoo june28th
took hair sample June 28th
when they took sample they did not go completely to the scalp but kinda close. Thank you for your time
July 4, 2017 @ 7:30 pm
What if you abstain get clean hair shave it off and the if you know your going to have a hair follicle test done then use a light glue on you legs sprinkle the clean hair on wait for it to dry and then let them shave it off
July 5, 2017 @ 4:42 pm
No, no, no.
The lab techs aren’t stupid – they cut hair every day, for a living.
You’ll be failed for tampering with the test, if you do that.
July 5, 2017 @ 2:45 am
Did coke on 7/3/2017 before that no coke use. I have urine and hair test that I can take anytime in the next 2 weeks. What do you suggest. Should I take it in 4 days since my urine would be clean and the coke won’t show in my hair yet. Or should I wait as only as possible and cut my hair right before test.
July 6, 2017 @ 4:40 pm
The biggest risk here is the urine test, so I’d wait until it’s completely out of your system before you go in.
I highly doubt you’ll fail the hair test, given that you’ve only used coke once in your life.
July 14, 2017 @ 10:26 pm
If I did meth(one night) in May and do a hair test tue will I pass?
July 15, 2017 @ 4:13 pm
Yes, you will probably pass a hair test. It’s designed to detect long-term, moderate-to-heavy use. That’s not you.

Hello, I took about 4-5 hits off a blunt april 2nd, didnt smoke after that, then I smoked on a gram from june 4th – june 6th, and around 2-4 weeks ago I did these methods, I did the macujo about 3-4 times in a row, i bleached my hair then dyed it, then bleached it again, then dyed it again, then rebleached it a final time but didnt dye it. I just recently cut my hair down to .5 inch about 2 days ago. What are my chances of passing a hair follical test within the next 1-2 weeks? Should I rebleach and redye my hair again and do the macujo methods right before the hair tests? Or do you think I will be fine the way I am.
July 19, 2017 @ 4:06 pm
You are doing all you can. Recommend you do the Macujo again, right before your test. Day before or day of.
July 18, 2017 @ 4:05 pm
Thank you for taking the time to respond to everyone that have been unsettled by hair testing. There is a lot of great info here and I certainly appreciate it! I have a hair test coming up this week. I just started the Macujo method last night. I am hoping to complete it twice a day for 4 days with the Ultra Clean on the day off. I did coke back to back 2 weeks in a row, one month ago, and then about a month prior to that. I quit smoking weed about 2 months ago but mostly ate edibles and used CBD on my skin for soreness. Obviously, without the treatment I would fail. Based on your experience, what do you think my odds are of passing? Is there anything else you can recommend for me?
Again, thank you for your time!!!
July 19, 2017 @ 4:04 pm
Thanks for the nice words 🙂
You qualify as a moderate user, based on your description. This puts you in the gray zone. You may or may not pass.
FWIW, Macujo not a foolproof solution that strips *all* traces from your hair; the goal is to clean enough of the trace metabolites out of your hair to cross below the minimum threshold.
Given where you stand, I would recommend a cleaning regimen.
July 23, 2017 @ 1:31 am
If my friend has smoked about 12 times in the last 2 months, last time being yesterday. He has a hair follicle test in 2 months. What are his chances of being passing? Also, if I’ve smoked only twice in 2 months last time being the 4th of July with about 2 bowls overall, should I be worried if my hair test is also in 2 months?
July 24, 2017 @ 2:29 pm
You will probably pass your hair test, if that’s all you did in the past 3-6 months. But there’s a chance you could fail. You’re in the gray zone.
Your friend, on the other hand, will very likely fail a 90-day test.
July 25, 2017 @ 7:37 pm
Hi jay, just went through a lot of your responses to people and see a lot of weed smokers here. I’ve also done a lot of research on this and am just looking for some peace of mind. I have a hair follicle coming up Friday and I am a recovering heroin addict. I had 5 months clean and then relapsed for one night. During that night I used a very small amount 3 times over the course of the day. The following day I felt so bad I did not want to go back to that life and haven’t picked up since. This was June 24th so a month ago. I plan on doing some form of the home detox stuff but a lot of ppl are saying I should be fine!
July 27, 2017 @ 2:13 pm
The methods described on this site will likely work for any drug, including heroin.
Weed is the most-discussed drug on this site because: a) it’s the most-used, and, b) it’s the toughest drug to beat, due to its staying power in your bloodstream.
My personal opinion is that you probably haven’t used enough to register on a hair test.
Best of luck!
July 26, 2017 @ 6:23 pm
If I used the Macujo or Gerry method will my hair stay clean for the test or is it only clean the day of. I have a test coming up but at random
July 27, 2017 @ 2:06 pm
Both methods strip all of the hair on your head. But new, tainted hair will continue to grow through your scalp.
This is why I recommend cleaning your hair the day before/day of the test.
July 31, 2017 @ 2:02 pm
I smoked about the equivalent of a joint over the past week. Nothing for about a year before that. Last time they tested me the took armpit hair. Suggestions?
August 1, 2017 @ 9:49 pm
I think you will be OK, honestly.
August 2, 2017 @ 11:23 pm
So, I only party about once a year (coke)… But normally party allot that one day. It has been 9 mths since my last party. I have a hair test sometime this week. I have very short hair (1/2″) and have always had short hair, years worth of pictures.
So, they are not going to find enough head hair to do a real test. Where are they likely to take a sample and how long will that sample possibly contain traces? From your chart above, it seems 8 months from anywhere other than head. And that they don’t normally go below the waist.
I have shaved my chest. I have trimmed everywhere else with a #2 razor (so not to be bald).
I think my chances are good and I am just being paranoid.
August 3, 2017 @ 9:53 pm
As long as you’ve shaved your body, you should be OK.
They may ask you to come back to take the test later, when your hair is longer. Or, you might just get lucky and they take the 1/2″.
August 4, 2017 @ 5:19 am
I was a heavy pot smoker up until January of this year. I’ve been clean for 7 months now and I’m a Hispanic female with thick, medium length curly hair which I’d cut and dyed in April about an inch or more. I have a hair follicle test in one week from now and my question is do you think by cutting my hair another inch or two before test will I possibly pass? I don’t want to cut my hair down to two inches or less. Please advise. Thanks in advance.
August 5, 2017 @ 9:59 pm
No need to cut your hair, as long as the tech does his job when taking his sample.
They are supposed to cut a 1.5″ sample, from your scalp line out. You probably have about twice that length of clean hair, right now (measured from scalp line out).
August 16, 2017 @ 7:59 am
Here is the quick version of my history. I had to take two hair follicle testes last year, which I failed both as well. First time I used some “detox shampoo” purchased from a local store where I am live. Needless to say I failed that one but I had already owned up to not going to be able to pass it. So my mom waited the 90 days and requested I take another one. I had then tried the method on here that requires laundry detergent, vinegar, ect. I also failed this test but my levels in my hair were much lower according to the laboratory place. I was able to talk my way out of that one with saying my hair just probably grew slower then expected. So after those two test I purchased the Aloe shampoo from the TESTCLEAR website (this was in 2016). I never ended up using it. My question(s) are: 1) Does this shampoo expire? 2) my hair falls about 2.5 inches past my mid-back; would you recommend I purchase another bottle of the Aloe shampoo? I thought maybe having two bottles might increase my chances of passing? I did stop using opiates myself about two weeks ago (at home detox, never fun) but I continued to use meth for extra energy while coming off opiates though so I have only been clean off that for 3 days. I have prescriptions for anything else that would show up. My usage would of also been considered a heavy user.
August 17, 2017 @ 9:55 pm
I don’t think the Aloe Rid “expires”. Never heard of that, anyway.
The amount of shampoo you need depends on how much hair you have to clean, and how many days you plan to wash it.
Generally, it’s a good idea to do the Macujo a few consecutive days before your test… all the way up the day before (or of) your test. Don’t wash and then wait a few days – fresh, tainted hair will grow through your scalp during that time.
Good luck on your test!
August 23, 2017 @ 6:53 am
Hi! So my son is moderate smoker, last used 8/18. He will have a hair text in about 6 weeks. The thing is, he is half black and keeps his hair very short, probably an 1/8 or 1/4 inch. Definitely not enough to get from his head. He does not have a lot of hair on his body naturally. If he were to shave it all off in 10 days, would the hair that grows back be clean when he tests? Thanks!
August 27, 2017 @ 9:39 pm
Because he is a moderate smoker, your son will probably need to wait a total of 30 days from last use before shaving to ensure whatever hair grows through is clean. This assumes he doesn’t use again, of course.
Doing the quick math here, that means he should shave around 9/15 or so. That won’t leave much hair for testing – 2 weeks of growth is not nearly enough.
Most likely they will either:
– urine test him
– fail him for lack of sample or,
– ask him to come back after his hair has grown out more.
Best of luck!
September 5, 2017 @ 6:55 pm
I have a hair test coming up next week. I use to be a heavy pot smoker for the last few years. I recently stopped smoking since June 15th and I was wondering if I would be able to pass the test if I were to take the test sometime next week or even the following week. During that time I was getting haircuts every week till the week of August 4th. I have let my hair grow since I use to cut it pretty short and they would need a long hair piece for the rest. I have also been working out daily and was wondering if I would pass the test or should I wait longer. Thanks 🙂
September 8, 2017 @ 6:26 pm
You might pass if you cut your hair to less than 1″ all-around your head. This should get rid of any tainted hair, but your hair is not quite long enough to sample for a 90-day hair test.
Warning: The lab may ask you to give a body hair sample, instead – so shave that off/down, too.
September 6, 2017 @ 5:23 am
Hey J, I took about ten mg of vyvanse for about 4 or 5 days a month and a few days ago , I have to take a hair follicles next week. You think I’ll pass, let me know and explain the cut of leve on ampedamies
September 8, 2017 @ 6:20 pm
It is highly UNLIKELY you will pass, if they test for amphetamines. If you have a script/prescription for the Vyvanse, then bring it with you.
September 6, 2017 @ 4:29 pm
I’ve been doing Percocets for about a year now. I’ve also been a heavy smoker , & have tried cocaine twice in the last 3 months. I have a hair test in 7 days. I just died my hair 3 days ago , and haven’t done anything since. What all should I do to try and pass the hair test ? And will any of the detox discolor my hair?
September 8, 2017 @ 6:06 pm
You are at high risk, so try one of the cleaning methods described on this page: https://hairfollicledrugtest.info/thc-detox-clean-hair-home-remedies/
NOTE: the Macujo method will NOT discolor your hair. The Jerry G method will.
September 7, 2017 @ 9:55 pm
Question: I am a female, 41, 5’6″ brown medium curly hair 180lbs. I took a hair test oon 9/5 and waiting for results. I was 67 days clean day of test. On 6/10 I took 2 puffs of mj, 6/23 -2 puffs, 6/24-2 puffs same for 6/27, 6/28 and last day was 6/30. Prior to that it was like once every 2-3 months. What are my chances of passing?
September 8, 2017 @ 6:04 pm
Not that great, sorry to say. Let us know how it turned out!
September 7, 2017 @ 11:10 pm
I took 10mg hydrocodone almost 25 days ago.. not a frequent user and this is the only
thing that’s been put into my system over the past 90 days. Will it show up in my hair test that i have to take tomorrow. thank you!!
September 8, 2017 @ 6:03 pm
Probably will NOT show up. Good luck!
September 12, 2017 @ 4:03 am
Hey. Been clean for 5 years. Slipped up after hurting my back. Long story short I’ve been taking morphine for the last 2 weeks, not crazy amount but probably enough to detect on a follicle test. Got called for a hair test this month. I have long hair, down to my shoulder blades I guess is the best description. I need to know what is my best plan of action.
September 14, 2017 @ 5:42 pm
If you have a doctor’s order for the morphine, then bring it with you and show the lab tech.
If you don’t have a doctor’s order, then you should try to strip your hair if at all possible.
Best of luck!
September 12, 2017 @ 7:37 pm
Hey there guys. I’m just sharing here. I haven’t smoked any mary jane the whole year except the month of May and June where i was smoking almost every day. I stopped completely at 17 July, been clean ever since and I may have a hair test tomorrow. I’ve balded my head twice since i stopped. I’ve no idea how its gonna go. But wish me luck! I’ll let you know how it turns up.
September 13, 2017 @ 11:52 pm
Love this site and hoping for some feedback. I had two chocolate edibles in Colorado on June 2nd. Prior to that time, I smoked twice in the past 10 years. I was just offered a new job and will taking the hair test in a few weeks, which ends up being exactly 110 days after eating the chocolate. What are the chances that I pass??
September 14, 2017 @ 5:49 pm
Sarah, you didn’t use much THC (most likely). I’d say your chances are very good you will pass.
September 14, 2017 @ 3:11 am
I have smoked 4 times over the last 12 months. Once Sept. 2016, once March 2017, and twice during July 2017. Each one a bit of a joint, or an edible.
I will likely have a hair test done May 2018. I have stopped since the last usage in July 2017. So I should be roughly 9 months clean come the hair test.
My question is, is there a set standard of how much hair is tested? I am a woman with medium length hair (down to the shoulders), and I would prefer not to go a pixie cut route come Spring. My colleague is skeptical they would only test 1.5 inches of hair IF more hair is available – they would test more. Sort of unfair, seeing as he easily cut his hair before the test, so they could only sample clean hair. I don’t have that easy of an option.
Two companies that test (not the one the company uses, I can’t find their website), when I looked at them standard do 1.5 inches of testing only, but companies can request a longer length be tested without issue from what I read. The company I likely am going to get may just be that paranoid (they’re very conservative)… but it’s hard to say.
Do you think it would be the safe option to do a bleach this Winter Break? Or a Pixie cut this Spring (fingers crossed, my hair is long enough by then). I was thinking I can bleach the hell out of my hair, and use a detox shampoo in conjunction with the bleach this Winter, and dye it blue for the month I have off as the “reason” for why I damaged my hair so bad at that point (I would dye it brown again come January) – so then they wouldn’t be able to detect anything from December and before… and I would still have my hair (albeit fairly damaged). It also shouldn’t look suspicious since at that point there would be about 5 months of healthy growing hair by the time they see it anyways.
What is your take? I don’t want to take any chances. Thank you for taking the time to make this website, it’s very well formatted and cited, I really appreciate it.
September 16, 2017 @ 5:53 pm
First off, don’t worry – whether your test if for 90 days or 6 months, you should test clean if you’ve been abstaining since July… and your hair test isn’t until next May!
The thing to remember is that the lab tech who takes your hair sample is instructed to cut the sample from your scalp line out, so they take only the most recent hair as their sample.
If your test is for a 90-day look-back (standard), then they’ll cut 1.5″ from your scalp outward. To do this on someone with long hair, they first cut full-length hair strands, then cut the sample down to the youngest 1.5″. This may appear like they are sampling more than 1.5″, but they aren’t.
September 15, 2017 @ 7:36 pm
I smoke maybe 1 or 2 hits of a joint back in maybe June or July but never smoked before that and haven’t since and I have a hair drug test in a week will I pass???
September 16, 2017 @ 5:54 pm
Yeah, I think you’ll pass. Let us know how it turns out!
September 21, 2017 @ 6:39 am
I read somewhere else that one person can’t fell a hair test just by in halling it. Example say u in car and u RIDEING with some one smoking but u don’t smoke. It saying that u can’t fell a hair test like that it that true r not
September 22, 2017 @ 6:02 pm
That’s correct: you can’t fail a hair drug test just through second-hand exposure (breathing in a car included).
paranoid as fuck!
September 25, 2017 @ 5:54 am
hi! i just applied for my first job doing at home assembly for a company today (sunday) i’m a little worried because saturday night i took maybe 2-3 hits from a bowl that had less than .5 g in it and prior to that have had 2-3 hits from a joint well over a year ago (that was my first time ever). i hear hair follicle testing is becoming more and more popular these days and i’m worried that that’s the method they’ll use if i even need to be tested, will that small amount of weed show up on a hair test?
September 25, 2017 @ 5:38 pm
No, I seriously don’t think one use like that will show up on a hair test.
Good luck on the new job!
September 28, 2017 @ 3:47 pm
Hi Jay, I had a hair test yesterday for a new job and my last time using cocaine and ecstasy was 108 days ago. I have had 3 hair cuts since then and my hair isn’t that long anyway (it’s just under 1.5″ now) I am bricking it that there might still be traces of drugs in the tips of my hairline if I haven’t had enough cut off. What do you reckon my chances are? If not enough hair has been cut off can they test for more than 90 days?
September 29, 2017 @ 8:51 pm
You are right on that line, but I’d say a pretty good chance to pass if your hair is less than 1.5″ and it’s been 108 days.
October 17, 2017 @ 5:21 pm
Haven’t done any drugs in 2 years an old friend stopped by did 2 lines of cocane and what do you no hair test is two weeks I’m a IDOT!!! I no I’m stupid and wish I could could run time back
October 18, 2017 @ 7:22 pm
You will very likely pass. That’s not much use. Good luck!
October 20, 2017 @ 5:01 pm
Did cocaine about a month ago gonna do a hair test on a new job so scared 😳 will it turn out positive??
October 23, 2017 @ 4:48 pm
I was wondering about the shampoo. Does the shampoo simply cover the hair follicle to give it a false negative or will the shampoo actually clean it out. I did some blow about 2 months ago and may have a drug test (hair) in a month. I know that I would be right on the line of passing (~ 3 months) as I’ve been clean since. I picked up the shampoo just in case. If I start using the shampoo now will that get ride of the trace in my hair or should I be using it closer to the time of the test. I’m not worried about a relapse so if I could just clean the hair now it would be less stressful for me. Also can they test the hair to see if you used a detox shampoo because if so it may be better for me too just start using the shampoo now.
October 28, 2017 @ 7:18 pm
1. The old style Aloe Rid strips/cleans your hair, it doesn’t cover things up or stay in your hair.
2. No, they can’t tell if you’ve used Aloe Rid.
October 29, 2017 @ 2:40 pm
do you know if they use a hair follical test at a screening for a chemical dependency program?
November 8, 2017 @ 7:05 pm
Yes, some programs do use a hair test.
October 31, 2017 @ 9:03 pm
Inhaled one puff from a pen a 7 days ago. (Second time ever smoking, 1st time was 6 months ago). Unexpectedly have a job offer dependent on a hair test. What are my odds for passing a hair test?
Exercise 4-5 times per week
November 2, 2017 @ 9:00 am
Your chances of passing are extremely good, I’d say.
November 7, 2017 @ 3:36 am
I’m about to take a hair test that I had been prepping for for a couple months now. I’m at about 90 days clean. They are using arm pit hair which I shaved clean about 60 days ago. The regrowth should be trace free, correct?
Thank you. This was a very informative piece.
November 8, 2017 @ 6:47 pm
Yep, your underarms should be good to go.
November 22, 2017 @ 3:57 pm
Will I pass a drug test 6 days after using coke for the 1st time
November 23, 2017 @ 10:33 pm
Yes, you should. I takes about a week for the first bit of tainted hair to grow through your scalp, so I seriously doubt they could sample enough to fail you.
November 25, 2017 @ 3:58 am
Thanks for this helpful guide!
In the guide it mentioned THC and the metabolite is fat soluble. Does that mean if I exercise, more is deposited in my hair, hence lowering my chances of passing my test in a few months?
Thanks in advance!
November 27, 2017 @ 10:31 pm
Tom, that’s a great question. I did some digging around, but I can find no evidence that working out a lot either helps or hurts your chances of passing a hair test. I’m not sure anyone has studied that, specifically.
November 29, 2017 @ 3:50 pm
I read up that drugs can be detected in hair strand for about 90 days. Does they mean that the traces of the drug just cannot be detected anymore passed a certain time frame? Does the hair need to be cut after 90 day, and when the hair grows back it won’t contain any traces of drugs? I’m confused with this part!
December 1, 2017 @ 10:25 pm
Actually, drug traces can be detected in your hair as long as several years after you used them – if your hair is several years long, and they test the full length (which they do not).
The reason for the 90-day limit is somewhat arbitrary. Most hair tests test for prior 90 days (some 6 months), mainly on the theory that if you haven’t been a regular user for 90 days, then you probably aren’t addicted to the drug.
Also, some hair treatments and dyes can alter the accuracy of a hair test as your hair ages beyond 90 days, and labs don’t want to risk a false result if it’s not needed.
December 7, 2017 @ 7:05 am
Im a very light weed smoker maybe once every two weeka my last time smoking was a little over two weeks ago. And i did some MDMA back in October about a month and a half ago. Its was only .2 grams. What are the chances of a high concentration to show in my system For a hair test
December 9, 2017 @ 10:07 pm
You are at risk of failing the test.
The hair test is designed to detect REGULAR USE, and using every two weeks def. qualifies as REGULAR.
December 8, 2017 @ 9:01 am
Need help! So I haven’t smoked weed since I was 18 I’m 24 now. I decided to take 3-4 puffs of a blunt November 12th. My test is December 11th. What are my chances of passing a hair test?
December 9, 2017 @ 10:04 pm
Joseph, you should pass the test.
December 13, 2017 @ 3:45 am
I smoked on average quarter ounce of weed a month in total daily(small joints). I have a test December 21 and I stopped smoking on November 15. Wasn’t expecting to get the job for another 3 months but I must of impressed them pretty well. They already gave me a schedule start date on Jan 2. I’m scared to death about the test. I already have short hair no more then a quarter inch at its highest. But it is currently only about 1/8 inch by chance because I just cut my hair before they emailed me the offer. My body is naturally bald except for my pubic hair. I cut my nails after reading the comment and I’ve been doing the macujo cleaning the last 2 days. My question is what else do you think I should do in order to pass this hair test?
December 18, 2017 @ 9:56 pm
You are doing what you can. Make sure you keep doing the Macujo all the way up until the test day. Don’t stop a few days early, as some tainted hair could grow through your scalp line during that time.
Best of luck!
December 14, 2017 @ 5:45 pm
Ok so I barely smoke at all, I had a bacherlette party on sept 30th and smoked some and then smoked again on the 8th of October. I just got a surprised hair follicle test done yesterday the 13th. And they took hair from the baby hair at the base of my neck. Do you think I’ll pass the test since I barely smoke?
December 14, 2017 @ 5:46 pm
Plus I got my hair dyed from blonde to dark hair so will that give me a better chance too?
December 18, 2017 @ 9:50 pm
I’ve seen a couple of studies in Europe that claim hair coloring can reduce the footprint.
But the only type of hair treatment that lots of real users claim works is the Jerry G method, which involves repeated bleaching. Not for everyone, though.
December 18, 2017 @ 9:46 pm
Yeah, I think you’re safe. Good luck!
December 14, 2017 @ 11:29 pm
I smoked three hits of marijuana about two months ago and a full joint about one month ago. These are the only two times I’ve smoked. I have a hair test in one week. How likely am I to pass?
December 18, 2017 @ 9:46 pm
You will probably pass. Just don’t do any more.
December 15, 2017 @ 7:02 pm
What if you have consumed an edible? I was given a 200 mg. candy bar about 10 days ago and ate it over the course of about 8 days to help with the residual pain from a hip replacement. Does it take longer when eating thc or is it the same time to process it from your system and hair?
December 18, 2017 @ 9:44 pm
Compared with smoking, it takes quite longer for THC you get from edibles to metabolize and for the chemicals they test to enter your bloodstream. The only practical benefit this gives is that if you get hair-tested fairly quickly after eating, and you have NOT been using regularly before that, then you have a slightly better chance of passing vs. smoking the same amount.
This benefit of edibles over smoking disappears after 2 weeks.
This article explains more about how fast THC enters your bloodstream for the various ways of consuming it..
December 18, 2017 @ 5:28 pm
Have been an off and on user for a long time. Ate an edible in July (single gummy bear), then had another edible in the early part of October. This was consumed over four or five consecutive days (6 inch taffy, consumed in pieces). I’m a short and heavy set guy with about 12 inches of hair. If I cut all my hair to an inch or so will that be enough for an upcoming pre-employment check?
December 18, 2017 @ 9:27 pm
I’m pretty sure you will not test positive for THC on a hair test.
January 13, 2018 @ 3:03 am
I have a test coming up in 2 weeks, I have stopped all drugs completely. I did coke approx. 85 days ago and I know I am on the edge on that one. I also stopped oxy 2 weeks prior to the test. I plan to do the macujo method 10 days before the test which I will wash 1 time a day and then on 5 days before do the macujo method 2 x a day with zygot on the morning of. although i have a prescription for the opiates I am hoping to avoid the doctor getting involved but have the note from them on hand just in case. I recently cut my hair to 1.5 in on the back with more on top. I plan to get a trim the day before to just enough for them to take. Should I do macujo method earlier or is 10 days sufficient? You all are beasts I tell you, reading this forum you have gone through great lengths I applaud you all
January 16, 2018 @ 10:37 pm
You’re doing everything you can. Do the Macujo every day, right up until the day of your test. A week or so is plenty.
Best of luck!
December 21, 2017 @ 8:33 am
I smoke 2-5 grams a week for two years. I quit cold Turkey yesterday because I found I have a hair test for employment in mid February. I’m assuming my chance of passing are very slim? Yes? No? Help!
December 23, 2017 @ 10:06 pm
Unfortunately, you’re right – you are not in a good position. Recommend you try one of the cleaning regimens discussed above.

I quit smoking back on the first of November after smoking daily for a long time. I am supposed to get a hair test on the 1st of February. I had
back pain today 12/21 and without thinking I took a 5/325 hydrocodone- acetaminophen. I am now very worried about my test. Should I be concerned? I haven’t ever taken a hydrocodone before.
December 23, 2017 @ 10:10 pm
No, I wouldn’t worry about it too much. Bring the bottle with you to the test that shows your name on the prescription. That’s a pretty common painkiller.
December 23, 2017 @ 5:53 am
I’m a somewhat infrequent user. I have finished an eighth of average grade weed over the course of about 4 months all on my own. I am skinny, thin light brown hair, and exercise frequently. It will be about 40 days without smoking when I go in for my test. Do I have any chance of passing without treating my hair in any way?
December 24, 2017 @ 2:14 am
You should treat your hair to be sure.
December 28, 2017 @ 1:21 am
If I used the old rid version along with 2 other treatments advised in a consult, will my hair be good to sample anytime due to me being clean 2wks prior to using the expensive stripping detox shampoos regimen. Only cocaine and ice is in my hair that I’m worried about.
December 30, 2017 @ 4:22 pm
You want to Macujo-strip your hair every day, right up until the day of the test. If you strip it too soon, then wait 2 weeks without cleaning it, then what happens is 2 more weeks of tainted hair grows through your scalp, meaning you’ll test positive.
Hope this helps. Best of luck on your test.
January 4, 2018 @ 11:58 am
I ate pieces of a brownie for one week then smoked the next week(half a blunt a lil every day) this was earlier in December it’s been 2 weeks since then. What would u say my chances of passing a hair test were if I just did nothing?
January 6, 2018 @ 11:26 pm
On the borderline…
January 5, 2018 @ 10:31 pm
I was clean for a year and smoked twice in november and have a hair test in the middle of January do you think I will pass
January 6, 2018 @ 11:27 pm
Yes, I do think you will pass. Best of luck!
January 8, 2018 @ 9:37 pm
Jay Z, needs answers please. I did a couple bumps for NYE prior to that I did about 5 lines the first weekend of December. Before that I did a few back on Halloween. I used a hair detox shampoo not the one mentioned on this thread, I also soaked hair in distilled vinegar… I had a hair folical test done last week. What are my chances of coming up clean?
January 9, 2018 @ 1:31 pm
I really can’t say – I don’t know what procedure / products you used. Sorry!
January 11, 2018 @ 4:02 pm
Im a heavy ish smoker about a 1/4 of high grade a week. I have a job offer that requires a hair test if I stop now and use the shampoo, how long would it take to be able to pass a hair follicle test?
January 13, 2018 @ 2:35 am
You’ll need to abstain 110 days to grow 90 days of clean hair through your scalp. If you don’t have that much time, then that’s what the cleaning regimens discussed above are for.
January 11, 2018 @ 11:31 pm
Hey jay I hadn’t smoked in over 6 months and was never a heavy user just at parties and weekends and a month ago I took 2 dabs just from dispensary wax I have a hair test in April should I pass if I abstain?
January 13, 2018 @ 9:37 am
You should pass, no problem.
January 16, 2018 @ 3:44 pm
I am a bald black guy i stoped using MJ back in August of 2017 but used again in December of 2017 very small amount 2 times what are my chances of passing a hair text in January of 2018
January 18, 2018 @ 11:42 am
You stand a good chance of passing. I wouldn’t worry too much.
Admirer of Jay Z
January 18, 2018 @ 12:23 am
Hey, first want to say thanks for all the great work and consistently replying after MANY years. Kudos man!
Second, (and more germaine to myself :P) I stopped smoking October 22/23rd of 2017. I have a pre-employment drug test on January 22nd of 2018. That would be at least 90 days since smoking however, A. I was a pretty dang heavy smoker, B. I am overweight (5’8/9 about 195lbs, a bit of muscle), C. I am keeping my hair at as exact as possible to 1.5 inches. Should I be able to pass this? Should I just try to push it back? I know it takes 5-10 days for it to grow out of your hair since last smoking, so that’s why I’m worried. I definitely made it the 90 days…. Just don’t want to get banned from re-applying because I failed.
January 23, 2018 @ 2:48 am
Yeah, you’re right on the edge. If I was you I’d cut your hair a bit shorter than 1.5″ to hedge your bets, and hope they accept that.
January 21, 2018 @ 4:14 am
I snorted crystal about a month ago only one line, dropped a double hit of acid two weeks ago, and took about 4 hits from a friends blunt roach a week ago. Other than that I haven’t used anything for a couple months how likely is it I’d pass a hair test.
January 23, 2018 @ 10:40 am
Believe it or not, because you’ve only each type of drug once, you’ll probably pass.
The test looks at each drug separately – and you’ve not done enough of any one drug to be at much risk.
January 30, 2018 @ 1:01 am
Jay – Love your work.
So here’s a theory, slightly contradictory to your awesome analysis that I wanted to run by you.
Weed needs to build up enough in the blood for it to penetrate hair follicles right? Also, weed clears out of blood within a couple days right? You state a joint or at most half a joint typically isnt enough to have you fail a test since enough doesnt build up to penetrate the follicles.
So isn’t it theoretically possible to be able to smoke once every 5-7days (once meaning 1-2 hits) or at most 14 days, and still not fail a hair test? You smoke, not build enough to penetrate the follicles, it passes through your blood, and ur at it again.
What am I missing?
February 1, 2018 @ 10:59 pm
What you aren’t factoring in is the fact that THC metabolites build up and are stored in your fat cells, which adds a buffer/baseline that takes more than a couple of days to drop off.
Don’t try to out-think this.
Either abstain for 110-120 days before your test… or cut or strip your hair. and take your chances.
February 3, 2018 @ 10:06 am
My friend took a small line of coke about an inch long just over a month ago. Before that he had not used in around 11 months but was a heavy user back then. Will this show up in a hair strand test in the near future? ….Thanks
February 6, 2018 @ 11:04 pm
No, I don’t think your friend has anything to worry about.
February 24, 2018 @ 3:28 pm
Oh everybody my name is Lee. My natural hair color is dark brown but I dye my hair once a month because of gray hair. I’m 32 years old and have tons of gray hair LOL. I have been Clean going on 15 months and my children back and then I relapsed for about a three week time on methamphetamine. Come to find out I was gonna have to do a hair follicle test through the department of family children services. I have been through this already so I told them that I would get the test but I would get one done privately. They gave me a day and half to get this done. I went through LabCorp with a five panel hair test. So here’s my method and it worked for me:
– Night before test: I thought my hair down with red apple cider vinegar. I left for 30 minutes with shower cap.
– Don’t rinse vinegar, I worked in the Neutrogena T sal shampoo. Leave on for 30 minuets.
– Rinse hair with tide laundry detergent.
– Then I bleached my hair with Clairol® 8 oz. BW 2 Powder Tub and a 30 creme developer. Leave in 1 hour. Use conditioner afterwords and wash out.
– The next step I used was Heet from the automotive section. Yellow bottle(methanol) This is one of the biggest steps and most important. I soaked my head down all the way with this stuff. Do not get it in your eyes or your mouth it is poison.I put a shower cap on my head and I went to sleep. Leave all night.
– Next morning I washed the Heet out with the T-sal shampoo.
– I bleached again. I couldn’t leave it in for more than 15 minutes because it hurt so bad. Please leave as long as you can but no longer than hour. If you can’t it’s OK don’t worry.
– Soaked my hair down again with Heet Put in a shower cap and left it for about four more hours.
– Rinsed with tide.
– Dyed my hair back to the normal color.
– And last but not least I used a deep conditioner and left it in my hair for 30 minutes before I went to take the test.
This worked for me! I didn’t think that I could pass this test with the little time I had but I did! I do believe the methanol is the main ingredient that help me pass my test but make sure to follow all the directions. I know this will work And I’m glad I was able to figure this out! Guys I’m clean now and I realize I could’ve lost everything. I’m thankful that I got one more chance. You guys have a great day!
February 26, 2018 @ 9:27 pm
Congrats Lee! Your method sounds a lot like the Jerry G method, which relies on bleaching your hair several times. Happy to hear it worked!
April 30, 2018 @ 4:10 am
Where did you get the T-sal shampoo at ?
February 28, 2018 @ 6:47 pm
I smoked 92 days ago three days in a row and haven’t smoked since. I have a hair follicle test coming up this week. i bought the aloe rid. What are my chances of passing
March 3, 2018 @ 9:32 pm
Your odds of passing are excellent, I’d say. Best of luck.
March 5, 2018 @ 1:22 pm
I quit taking hydros around Christmas. I keep my hair short. Only about 1/2”-1” long. When will I be able to pass a hair test?
March 9, 2018 @ 9:37 pm
Safe bet is: first week in April. Good luck!
March 7, 2018 @ 5:20 am
Have a hair follicle test in about a week. Used about a gram of coke exactly one month ago. I did 2 grams December 20th, 2017. I told my employer that I shave my entire body regularly which I do. They said “that’s fine. They will probably just ask you to come back in a week or so when they can get enough hair.” It’s been a month and I’ve shaven several times including a few days ago. From what I’ve read I should be okay but I keep reading the tests can go back 90+ days. If that’s true how could my hair be clean now?
March 9, 2018 @ 9:56 pm
If your hair is less than 1.5″ long, then they CANNOT test 90 days back.
The standard hair test requires taking a sample that is 1.5″ long because that’s the length of hair that contains up to 90 days of drug history, for most people.
IOW, if they want to look back 90 days, they need 1.5″ of hair.
So… if all you have is 1/2″ of head hair to sample, then they can only look back ~30 days. If you have 1″, then they’ll get a 60-day window.
Make sense now?
March 9, 2018 @ 6:06 pm
I smoked about 4 joints over a 2 day period about a week ago. Do you think they will be able to detect that in a hair follicle scheduled for next week? I was peeing clean 5 days after so I’m just curious
April 23, 2018 @ 9:59 pm
No, they won’t detect use 2 yrs ago. You’re safe.
March 13, 2018 @ 3:05 pm
Failed HairConfirm at home test at levels of 0.59 pg/mg. Stopped smoking December 6th. Cut hair to one inch March 1st (should have been only January-present hair growth)
I was pissing dirty via home urine test at least until February 10th, I have a feeling I was urine dirty for at least 75 days.
Recently I cut hair to 1/2 inch on 3/7/2018 and I am sending off another test (should be February-present hair) . Lesson I learned as long as your urine is dirty there is a strong possibility thc metabolites are still being deposited in your hair.
Will update again.
March 21, 2018 @ 2:30 am
I haven’t smoked weed in a couple years (like 2015) I smoked a roach in a bowl last month that’s all, I’m very nervous with hair test I never had one. You think I’m good?
March 23, 2018 @ 10:16 pm
Yes, you are probably safe.
March 21, 2018 @ 9:47 pm
Hi there. Thanks for all the great information. I have an upcoming test for work that must be passed. The company just implemented this oh so lovely upgrade in testing so I am new to this. I have no idea if they are going to pull from my head or arm but sounds like if my arm is about a half inch they might according to my coworkers. I have a prescription for opiates if that shows up that I take as needed for neck pain. I’m assuming they just ask what medications you take up front to knock that stuff out just like a urine test.
I have not smoked since mid December and before that it was just here and there so I am not too worried about that one. However, I get about 15 (20mg) adderall from a friend once a month and take them for about a week straight around the first week of every month because that’s when I am my busiest. So it’s safe to say by the time I actually go take the test I will have not taken any for about a month. I should be able to buy a couple more weeks.
Do you think it is necessary to spend the money on the Aloe Rid or should the Ultra Clean do the job? I know you can’t assure anything but just curious on your thoughts? If deciding on the shampoo should i just focus on my head and shave my arms so they only have one option? Thanks so much!
March 23, 2018 @ 10:21 pm
You are def. at risk for the Adderall.
If I were you, I would do the Macujo or Jerry G several times the week before the test – and shave underarm/body hair. But that’s just me.
Let us know how it turns out.
March 25, 2018 @ 5:55 pm
I took 2 or three hits weed out of a bowl on May 15th 2017. I have a hair test this week. That was the first time in about 10 years. Do I need to worry. I haven’t done anything since then
March 28, 2018 @ 10:34 pm
No need to worry. You’re fine. Best of luck on your test 🙂
March 30, 2018 @ 7:05 am
About a month ago I pulled a muscle at the gym, couldn’t even get out of bed the next morning. My mother gave me her Tylenol with codeine , 30mg. I took 2 , at the most 3. I have never smoked weed or tried any other drug. I’m freaking out that this single use will show up. What are my chances of passing?
March 31, 2018 @ 10:40 pm
That’s probably not enough codeine to show up on a hair test. I think you’ll be fine.
April 1, 2018 @ 12:46 am
I have a hair test around June 18th and I am afraid that I am going to fail it. The last time I smoked weed was on March 23rd, and the last time I snorted coke was on March 17th. I was a heavy smoker before, and smoked on average 4 or 5 days a week. I rarely ever do coke. I know that the sample they gather will be 1.5 inches, however, my hair grows relatively fast Because of that, would I be more likely to pass my test, or does my hair growth not really factor in? Between now and then my hair will roughly grow 2 or more inches. Thank you.
April 3, 2018 @ 10:44 pm
You are right on the line, time-wise. Although you’re lucky to have fast growing hair, I would still cut your head hair down to 1.25″ all around and trim all body hair to be safe.
I say this because of your long-term heavy use. Good luck on your test!
April 1, 2018 @ 7:08 pm
Jay, Dude thank u so much for this info that u are giving us pot heads and curious people of the drug world, god bless u for u time and dedication, u take a big weight out of our shoulders, with thousand’s of pages that really don’t help out or give u information as clear as you do I greatly thank you in behalf of all of us desperate help seekers, also great way of labeling everything In the page from shampoos to do it you’re self methods to the thousands of comments, awesome jay. If people don’t know what the lords Shepherd meens then you are a perfect example of this saying. Really thank u thank u thank u, u might or might not know this fucked up feeling we users get when a job or government wants to judge u by a simple test that degrades all of us in the lowest way, sometimes we use “drugs” because of addiction, fun, one timers, curiosity, family problems, or just problems. But the government doesn’t think we are capable for a Job or maintaining you’re family or kids. Once again thanks JZ, God bless you.
April 3, 2018 @ 10:46 pm
Making me blush, man. Thank you for your kind words.
April 11, 2018 @ 3:44 am
Is leg hair better than head hair for follicle test. I took 4 small doses of Vicodin of 30 day period. Will it show?
April 13, 2018 @ 10:57 pm
No, leg hair is NOT better than head hair.
If you don’t ever trim leg hair, it can store a very long history of drug use (6 mos or more).
April 12, 2018 @ 5:26 pm
I havent smoked in 5 months and i took a follicle test a week ago to see if I would be able to pass a test for a job I wanna get into and i still failed. Is it because my hair is 4 to 5 inches long or can there be any other reason on to why I failed the test?
April 13, 2018 @ 10:58 pm
My guess is they opted for a 6-month hair test (vs. typical 90 day); if so, then yes, it’s probably due to your longer hair.
Billy R Sheats Jr
April 13, 2018 @ 12:22 am
So see if I got this straight, the hair follicle test says that I use but don’t specify when I used
April 16, 2018 @ 10:59 pm
Correct. Technically, the lab COULD (theoretically) estimate when you used. But they don’t do that.
April 13, 2018 @ 4:23 am
So I took a hit of some weed I think it was a dab about 4 weeks ago (1 hit). Two days ago I ate an edible weed chocolate. Well to my luck , a job I applied for called me today 4-12-18 and I have to pass a hair follicle test to get the job tomorrow . Am I at risk of failing?
April 16, 2018 @ 11:00 pm
Relax: you will very likely pass.
April 19, 2018 @ 4:40 pm
I have a question, I smoked three hits of a wax pen yesterday and havent smoked for over a year, i used to smoke regularly but like i said its been well over a year since my last time. I understand the wax pen is a little more potent but my question is will it show up on either a urine or hair test? Not sure which one ill have to do but i know it will be sometime after the next two and a half weeks. thanks so much
April 19, 2018 @ 11:07 pm
Hair test? No.
Urine test? Maybe.
May 3, 2018 @ 3:37 pm
I smoked a ton of weed in Colorado last year. I havent smoked in exactly 6 months. I need to test to get a good job – reason im paraniod is because of the amount I was smoking – and when it usually only takes me 3 weeks to have clean urine, it took me 7 weeks this time. I would think Im good with 6 months, but i cant afford to no get hired. Should I buy all this crap to cleanse my hair? Thx JZ
May 6, 2018 @ 9:24 pm
No, don’t waste your money to clean your hair. Just make sure your hair is no longer than ~2″ on your head when you get tested.
May 3, 2018 @ 9:07 pm
hi jay, got a scenario for you. i took pain meds for the first half of 2017, about 12 per month and by years end i was down to none. early january of 2018 i took tylenol and codeine for almost a week. so since then its been 98 days as of april 21st that i have been clean. since then i have also shaved my head twice down to under a half inch. armpits the same, chest and goatee.
by the time i may take the test it will be 120 days since i ingested anything. would i have anything to worry about? and also if i sweat on a hat and have since worn that since ive been clean would that have an effect also or no because everything in just in the hair follicle itself.
would some aspects of the cleansing methods be a benefit or to not bother? thank you
May 6, 2018 @ 9:23 pm
As long as your hair is 1.5″ or thereabouts at the time of your test, you should test clean.
May 8, 2018 @ 8:39 am
Hi Jay. Great info. Took 5 5mg/500 vicodin total over 2 days after not touching the stuff in 18+ months. If I get offered a job in the next 2-3 weeks should I be concerned about this showing up in my hair and buy shampoo or can I be worry free? I’m going to shave me head prior to the interview so that should buy some time as well.
May 9, 2018 @ 9:18 pm
I think you will probably pass without needing to strip your hair. There is a slight chance you will fail due to the amount you took, but I seriously doubt it.
May 11, 2018 @ 10:09 pm
I have left a few comments and never received a reply. I’m sure your a busy person and have a personal life as all of us. I just took a follicle test yesterday. I prepared my hair doing the Macujo method and to my luck they said my hair was too short and took arm pit hair like 1/8″ from the skin. I consider myself a very infreaquent user. Ate a .5mg gummie on 4/13. Took one hit from a pipe the weekend before that. And one hit the weekend before that. I have been clean since 2009. Do you think I will pass? I have researched and found the growth rate for armpit hair is very very slow.
May 18, 2018 @ 9:10 pm
Guy, sorry for the late reply. I get busy at work like most people. YES, I think you will pass.
You really haven’t done enough THC for your metabolites to rise above the cutoff level in your blood, so there’s almost no chance you will fail.
May 15, 2018 @ 9:39 pm
I have a hair test within 2 to 6 weeks. I was a huge pot smoker, like 3 blunts a day. I have stopped and have not smoked in a little over 100 days. I have also paid for the aloe rid shampoo (which was really expensive). What are my chances of passing? Should I still do the macujo? Is just applying the aloe rid enough? HELP PLEASE
May 18, 2018 @ 9:04 pm
You need to do the entire cleaning regimen for Macujo to work. Don’t JUST use the shampoo. Best of luck!
May 20, 2018 @ 7:26 pm
Clean for 2-3 yrs. Took 2-3 hits a week ago from a pipe. That is all. Have hair test within 30 days. Am I wasting my money buying Aloe Toxin Rid Shampoo? Also, would it be helpful if I just use the Ultra Clean 1-2 days before the test?
May 21, 2018 @ 8:39 pm
2-3 hits in the past year probably won’t fail you. I would not spend all that $$, if I were in your chair.
May 20, 2018 @ 7:44 pm
will the ultra clean do any good without the Aloe toxin shampoo?
May 21, 2018 @ 8:38 pm
It might, but everything I’ve seen and read says that the key ingredient in Macujo is the older (expensive) version of that shampoo.
May 21, 2018 @ 6:16 pm
Hi Jay Z I haven’t smoked in years but this past Saturday I smoked three blunts back to back then that was it I may have to take a hair follicle and a urine test tomorrow or by the end of this week. Do you think by then I should be cleared if I just eat fruits and veggies and drink water? Or do I need to take some supplements and detox drinks and the hair follicle method you have on here?
May 25, 2018 @ 8:32 pm
Relax – you will probably test clean, is my strong guess.
FWIW drinking lots of water, eating good food, drinking detox drinks and taking supplements have almost ZERO effect on a hair test.
Those are more effective on a urine test.
June 4, 2018 @ 11:38 am
Hi. I took some bumps on March 11 time user in years. Nothing before and nothing ever since. Waited 7 days and remove hair from entire body and kept hairs short since then. Did hair test may 31. They took underarm hair. What a the chances of it coming back clean.
June 6, 2018 @ 8:18 pm
I think the odds are good you will pass. Let us know how it turns out!
June 5, 2018 @ 10:49 pm
Hi! I’ve never been a heavy smoker, maybe 1 every month or so and usually only take one hit cuz I have no tolerance. About 1 and half years ago for a few months I was taking about 1-2 hits a day and then I stopped. More recently, about a 3 months ago I had taken a few hits over the course of several days. Then nothing until 2 weeks ago. I had a minor surgery but was super nauseas because of it and smoke for about 5 days, maybe SMALL hits a day. Now I have a follicle test coming up within the next 2 weeks. Am I good or do I need to cleanse and if so… how much?
June 6, 2018 @ 8:17 pm
Aimee, from what I can gather you’ve used three times since January – right? On this basis, you will probably pass – but if you HAVE to pass, then consider stripping your hair using Macujo/Growman or Jerry G methods just to be sure.
June 6, 2018 @ 5:21 pm
Hey Jay got a question. I did about a gram of coke during march 22-29th and nothing else after. I shaved my head to a half inch aproxametly 50 days after, today I went to go get a hair test and they said my head hair is to short so they shaved my leg hair as a sample. Am I screwed?
Another question lets say hypothetically I was a heavy drug user (coke)at the age of 18 like everyday for 6 months. Decided to get sober and never touched it again for 3 years. So being sober for 3 years at the age of 21 will the drug still show up in my armpit hair or leg hair if not cut because the tainted hair will remain untill its cut off right? In this case with someone who never cut or shave his armpit test positive if armpit hair is used as a sample?
June 6, 2018 @ 8:13 pm
Just one use of coke in a year won’t cause you to fail a hair test – even if they took a leg hair sample.
Three years after quitting, you won’t fail a hair drug test – no matter where they take the sample.
June 11, 2018 @ 5:24 pm
I had a hair follicle drug screen March 1 of this year. It came back positive for cocaine. Much to my surprise since I’ve never done any drugs ever (no judgement on anyone who has). I was fired from my job. I took another drug test on my own right after that for confirmation because I legitimately thought the lab had made a mistake. I also failed that one.
A few months later I found a new job and passed the pee drug test. Last week I took another hair and pee test to see where I stood. I also failed that one (only failed the hair). I still don’t understand how I ever failed in the first place. I do take Rx adderall but the MRO said that couldn’t cause a false positive. Basically they said I had to have taken cocaine, there was no other way for it to show up in my hair. I’m at a loss right now. I will be drug screened again at the end of the month (not sure what type of test) and I’m terrified of losing my job again. This has been a nightmare. I’ve read TONS of mixed reviews on the shampoos to strip your hair of drugs. I’m willing to do whatever is necessary. I just want to be as sure as possible that my efforts will be worth it. I know this will ruin my hair, but it will be worth it to keep my job.
Thanks in advance for any advice!
June 13, 2018 @ 3:30 am
Have you been taking antibiotics?
Amoxicillin can cause a false positive for cocaine: https://www.drugs.com/answers/what-are-all-the-possible-causes-of-a-positive-451392.html
Some topical anesthetics use cocaine.
Coca leaf tea contains cocaine, as well.
Other than these substances, I’m not aware of anything else that gives a false positive for cocaine.
June 11, 2018 @ 10:03 pm
Hey Jay Z. I am a 300lb man who smoked every day. 1/4 of weed every 3 days. I stopped smoking. I have a test in about 130 days or so. Would I be okay if I cut my hair down before the test? I am losing weight. How much days without smoking do you think a big dude like me needs? It’s for a DOT test. I am.getting into trucki g
June 13, 2018 @ 3:24 am
Mike, your weight actually has very little to do with the length of time you need to wait before your blood clears of THC metabolites.
You’ll need to wait the same amount of time as anyone else: about 110-120 days of abstinence, then cut your hair down to 1.5″ all around (for a 90-day DOT).
Good luck 🙂
June 19, 2018 @ 12:10 am
Hey Jay, I quit smoking weed on the day after 4/20 this year. Since then I took 3 individual hits off a pipe. I’m gonna be applying for a job soon that has hair test. how long should I wait at the minimum before I apply and take the drug test? also prior to me quitting id only smoke 3 or 4 times a week, half a bowl each time.
June 20, 2018 @ 3:13 am
I wouldn’t take a hair test before mid-August, if I were you.
June 22, 2018 @ 8:33 pm
I was reading the Quest Diagnostics page about their cutoff levels and I noticed that their listed cutoff for Marijuana (THC-COOH) was 1pg/mg. I read above in some other comments that it takes about ten days for an average user to get below the 50ng/mL concentration that most tests check for. About how long should it take to get below the 1pg/mg level to start growing clean hair?
June 23, 2018 @ 3:08 am
Another great question!
These two concentrations are for two different materials (blood vs. hair) and are functionally equivalent:
In other words, a cutoff level of 1 picogram of TCH-COOH per milligram in hair is equivalent to a TCH-COOH concentration of 50 nanograms per Liter of blood.
Hope this makes sense.
June 27, 2018 @ 6:07 am
Heavy drinker 750ml vodka daily for years. Do the hair treatments work for alcohol or just drugs. Upcoming hair test worried. Tha k you
June 29, 2018 @ 2:52 am
Unclear on alcohol. Or at least, there’s not enough data/experience out there for us to know for sure.
But the hair-stripping theory behind these regimens work the same way no matter what the substance is.
July 3, 2018 @ 8:50 pm
So I am a super infrequent user (pot) in the last 90 days I’ve probably taken a total of just 5-6 hits (j, and a pen) and when I say hits, literally a puff. hair test in about 30 days – black hair quick growth etc. How are my chances looking?
July 6, 2018 @ 2:21 am
You’ll very likely pass with no problem. That’s very little use.
July 5, 2018 @ 5:10 am
Hi, I was a heavy cannabis user multiple times a day. I work in a field where it highly unusual to test for drugs so I did not abstain while applying for new career positions. However the position I really wanted require that I take a blood, saliva, urine and hair follicle test for all drugs within 30 days. Also with the added pressure that if I fail any of the tests my findings would reported to the proper authorities for punishment. I immediately stopped using cannabis and researched on the internet and discovered the Macujo method. I ordered the Old style aloe toxin rid shampoo which took 3 days for me to obtain. While waiting for the shampoo, I ran until I was drenched in sweat which took 30 minutes each time and continued running daily until the day of the test. Also, I went to sauna every other day 30 minutes until the day of the test, I did body cleanses and detoxs everyday along with consuming a high fiber diet. On day 17, my urine finally tested negative for first time. Now on day 4, of this ordeal the shampoo arrived I started doing the Macujo method for total of 28 times. On day 25, the day of the test, I did the Macujo method and followed it with Zydot Ultra Clean twice. I just wanted the test to be done so I did it 5 days before my original scheduled date. A week later I found out that I passed all the forms of testing. That night I celebrated by returning to cannabis again. My advice is trust the process. My spouse was skeptical while I was washing my hair all those times (also yes it burns your scalp). Omega labs tested my hair and their website states there is no way their method for testing hair could be beaten. Yet, I am here to tell you that the Macujo method works if used properly. Also doing added exercise and dieting to pass the urine portion had the great benefit of me losing 10 percent of unwanted weight.
July 10, 2018 @ 9:47 pm
Hey I took a hair test yesterday for pre employment. I had done coke about a month ago and have been sober before that for about 3 months. My hair length is only about 3/4 an inch but they still took the sample from the scalp. Think I will pass?
July 11, 2018 @ 2:08 am
If you only did one or two lines, then I’d say you have a good chance of passing.
Please let us know how it turned out!
September 25, 2018 @ 4:39 am
Did you pass? I’ve got the same situation
July 16, 2018 @ 1:52 am
Stopped smoking june 5th. I have a hair test coming up in a few months. My hair grows pretty fast and I get regular haircuts. When do you think I could pass? I can put it off if I really need to. Thanks!
July 17, 2018 @ 10:24 pm
If you’re a heavy user, then I’d wait until October before taking a 90-day test.
July 20, 2018 @ 9:14 pm
I have a follicle test on August 23rd. I have smoked weed a few times in the last couple weeks. If I stop smoking now should I wait until closer to the test to do hair treatments or try doing as many as I can before then. With lighter use and advanced knowledge of my test date can I get away with just using the ultra clean shampoo?
July 22, 2018 @ 10:39 pm
All hair cleaning regimens should be done as close to the test date as possible – including the day before the test. Different regimens take more days than others, though.
The Macujo method is often performed every day from 3-5 days before the test until the day before the test.
The JerryG method is usually done once or twice 1-2 days before (it can be done in a single pass).
July 21, 2018 @ 12:55 am
Hi Jay Z
I’m a black female. My hair style is already bald (like Amber Rose) but not completely bald like Mr. Clean. I’m a extremely heavy smoker, I actually smoked today and there may be a chance that I take a hair follicle test next Thursday. Do you think if I shave my head completely bald and remove hair from all over my body I would pass? Or should I just keep stripping it with bleach & dye cause I bleach every few days and cut it every few days as well.? What should I do? I really need this job
July 22, 2018 @ 10:41 pm
If you have no hair to sample, then they will probably give you a urine test. In which case, you will fail – unless you have a cheat arranged for that.
July 21, 2018 @ 11:22 am
Hi Jay Z!
I really need your help.
Today it’s saturday and I will have my hair drug test on Monday. It’s for a job that I would love to get.
I haven’t done any drugs for the last two weeks.
Before that I was a HEAVY SMOKER (one gram of weed daily) for around one year.
I had an addiction to COCAINE (daily user 🙁 ) for around 1 1/2 year but I rehabilitated and I stopped since March 2018.
I messed up when I was unemployed. Not an excuse, I know.
The last time I did less than a gram of cocaine and I smoked weed was two weeks ago.
What’s funny it’s that I had a saliva test and I passed for cocaine but I had POSITIVE for opioids. No idea, maybe it was not pure cocaine but I’ve never done opioids in my life.
I haven’t done a lot of cocaine (1/1.5 gram per month) since March 2018. It’s just hard…
Anyway, I have done the Macujo Method 7 times in the last three days (I’m running out of time). I also used the Old Style Aloe Rid Detox Shampoo.
I used Ultra Clean once because my test supposed to be today but thanks God they had to reschedule and it will be on Monday. I have another package of Ultra Clean for the day of my test.
My hair is damaged but ain’t that bad, I can’t try Jerry G method because I’m sure I will get bald.
I’m waiting for this other product. It’s the half set of “Hair Razor Detox Shampoo”… I’m desperate! I have no clue if it works but I read good reviews. If you know about this product I would appreciate you pass the information to me. As soon as it arrives I will use it.
I’m gonna try to finish the macujo method til I complete 10 times.
I’m hispanic, women, 5’10” 169 lbs and I exercise 5x per week, drink a lot of water and eat healthy most of the time.
Do you have any recommendation?
Do you think I have a chance to pass?
P.S: I spent all the money I have in all these products T_T I hope they work and after all this expensive, long and painful rithual I’m not gonna do any drugs. Specially if I get the job.
July 22, 2018 @ 10:45 pm
You’ve done pretty much everything you can to help yourself. Please let us know how it turned out.
I don’t know much about Hair Razor Detox Shampoo… it’s a new product I’ve seen marketed pretty hard online recently. I’ll do some research to see if there’s any reason to believe it works. Can’t say for sure right now though.
Crossing fingers for you…
August 9, 2018 @ 5:37 am
Thank you so much for this! I am a very infrequent user (and only in the last 1.5 years). I may have smoked 1 time every month with my husband (who is a heavy user). I haven’t smoked now since July 6. I am actively interviewing for jobs and know with my industry a hair test is inevitable. Do you think I’m likely to pass if I have to take one in the next 2 weeks or should I take additional measures?
August 14, 2018 @ 9:26 pm
You are close on the borderline, to be honest.
Once a month isn’t much use, but if you’ve been doing 1X/mo for many months – say for more than a year – then the THC metabolites may have had enough time to slowly build up in your bloodstream.
If you really want the job, then think about cleaning/stripping your hair to be sure.
August 11, 2018 @ 6:00 pm
Hello there Jay Z..Well here’s my little situation…Im the smoker in the family and my husband smoked a joint with me a month ago and is being tested in 2 weeks what are his chances of passing the test? and what would you recommend?
August 14, 2018 @ 9:17 pm
Patty, your husband should be OK if that’s the only J he smoked in the past 6 months or more.
If he’s smoked more than a few times over the past 3-4 months, then I’d definitely look at doing the Macujo or JerryG hair cleaning methods. See this page to learn more about them.
August 12, 2018 @ 6:50 am
Hi! Im panicking! Found this page in my search for passing a hair follicle test, Im not sure my story is like any others so i need advice please
I got sober from opiates last fall and ive been on suboxone and also got my medical marijuana card since. Last week i was ordered to complete a hair follicle test and im wondering if the few times ive relasped will show up. Ive been going to my meetings and im doing great, the last thing i need is for my few slip ups (2or3x a month, most recent 7days ago) to take me back to square one. Ive recently switched from methadone to suboxone again in march and also am a heavy marijuana user. I have hip length thin hair,and im so open to cutting it but would that even make a difference? I am supposed to test within 4 days of today. Help!
August 14, 2018 @ 9:15 pm
1. if you’ve “slipped up 2-3 times a month” for several months, then you ARE definitely at risk of failing a hair test for opiates.
2. is your employer/court appointee OK with your use of medical marijuana? If they don’t know about it & are not OK with it, then you will fail for THC as well.
September 10, 2018 @ 5:58 pm
Hi! Need your help! Found this page and not sure my case is like others but thought i could use your expert advise.
I have only done coke one time (3 lines max) in April 2017. I have smoked weed in Colorado max three time (not more than 3-4 puff each time)- in Nov 2015, May 2016 and June 2016. No further use until now. I have given hair sample from leg for drug test last week. I have never shaved my legs before.
Will the drug use show up in my leg hair sample?
September 11, 2018 @ 1:55 am
No, I seriously doubt they will detect drug use that old in your leg hair.
Best of luck!
October 5, 2018 @ 3:17 pm
Okay, so someone I know has been drug-free his entire life. He had been laid off in June and has become extremely stressed over taking another job that is no good, so he started drinking 6 shots of vodka a night to relieve the stress. Since he believes in the medicinal properties of marijuana, I told him that maybe he should try that for stress relief instead of drinking. He finally did. He tried 3 hits, 3 different times within a two week span, last one being 3 weeks ago. Doesn’t like it and hasn’t done anything since. Again, completely drug-free his entire life. Well now he may have an opportunity for a job in the oil industry and they do Psychemedics hair follicle testing. He’s really upset because this is one reason he never touched drugs in the first place. He just submitted his resume and only did the pre-screening test
online so far, but if he passes and they end up calling him in for interview and then off for a drug test if they are interested, do you think he will be okay? It could be a few more weeks from now before they get to that point, if at all. He did order a Psychemedics home test to send off to see what comes up if anything just to be sure. What are your thoughts? Do you think he would be okay?
October 12, 2018 @ 8:29 pm
Your friend should test clean. I cannot see how 3 hits will register in his hair.
October 26, 2018 @ 1:57 am
I work in the oilfield and the company i work for is about to do work for another company that does random hair follicle and urine tasting. I’m going to buy the old style aloe rid toxin shampoo and the ultra clean to use before we start and while we are working for this company. My question is that if I use all the shampoo and havent had a random would i need to buy more and continue using if i havent got to my 90 days clean yet or would I be ok? Keep in mind i will be clean while doing this process and i havent used since I heard we were going to work for this company that does random hair follicle.
October 27, 2018 @ 7:13 pm
Great question – a lot of people get confused about this.
If it has been less than 100-110 days since your last heavy use, then the ONLY way Macujo method (the Aloe Rid method) will work is if you clean your hair right up until the day before your test. If you are within this window and stop, then tainted hair will continue to grow through your scalp.
Hope this is now crystal-clear.
Best of luck on your test.
November 3, 2018 @ 3:24 am
Hey, so I got laid off in Sep. and I quite smoking Sep. 8th, before that I was smoking at little almost every night. I am starting a new job on Nov. 26th and they said I will have a hair follical test, is there a chance I could pass it? I havent touched weed since the 8th of September, I have been eating healthy and working out. Any advice would be greatly appreciated
November 5, 2018 @ 7:16 pm
You are at high risk of failing. If you really HAVE to take the test and cannot defer/delay it, then I recommend using either the Macujo or JerryG cleaning regimens to bring the levels down in your hair (see links to instructions on the home page).
March 9, 2019 @ 4:57 am
I’m a heavy smoker of weed. How long do I need to wait to shave my hair after stopping smoking?
March 15, 2019 @ 7:49 pm
At least 110 days after last use, you can cut your hair down to 1.5″ or less. For super-heavy smokers, I advise 120+.
If shaving your head, wait 30 days before shaving. For super-heavy smokers, I recommend waiting until at least 1 week after an at-home Urine test proves you are clean.
June 7, 2019 @ 11:20 am
I am totally freaking out! I found out a couple days ago that the I will need a hair test for pre-employment screening! I had no idea companies did this. So basically for the past 1.5 years I’ve been smoking every night. What may help is my travel recently. From May 19-24 I didn’t have anything and again from May 31- June 2. Had a follow up interview after 2.5 months of silence then got the offer letter Tuesday June 4th and my heart dropped. So I stopped smoking immediately and bought supplies and washed everything my hair touches.
5’4 female, bleach blonde highlighted hair med length, 140lbs active athlete.
Day 1: washed hair with T/sal shampoo 3% Salicylic Acid.
Day 2: Macujo Method
1st time: Heinz Vinegar soak 30 mins
Added T/sal soaked 1 hour (with vinegar)
Without rinsing added Aloe Toxin Rid, let sit for 10 mins then repeated Aloe Toxin Rid for another 10 min
Washed with Tide
Heinz Vinegar Added T/sal soaked 45 (with vinegar)
Rinsed then added Aloe Toxin Rid, let sit for 10 mins then repeated
Washed with Tide
Heinz Vinegar Added T/sal soaked 45 (with vinegar)
Rinsed then added Aloe Toxin Rid, let sit for 10 mins then repeated
Washed with Tide
Heinz Vinegar Added T/sal soaked 45 (with vinegar)
Rinsed then added Aloe Toxin Rid, let sit for 10 mins then repeated
Washed with Tide
Day 4: plan to repeat 2 times.
Day 5: plan to repeat 3 times
Day 6: plan to repeat 3 times
Day 7: one Time in morning then end process with Ultra Clean Zydot. Then go to get tested!
This is what I’ve done and plan to do! Any suggestions or tweaks would be appreciated. Unfortunately i can not bleach my hair. This job is very very important! Dream job with six figures…wish me luck! I hope this works.
June 9, 2019 @ 5:51 pm
You’re doing everything you can do to test clean, given your unfortunate circumstances.
Please let us know how your test turned out – your detailed instructions can help a lot of others!
June 13, 2019 @ 1:10 pm
So I have a hair test coming up and I have been doing the Macujo method with the old school Aloe Toxin Rid Shampoo for the last week letting my hair soak 45 minutes each time with the vinegar I couldn’t find the nuetorogena pink but have been using the deep clean formula that has the salicylic acid will that work as well I stopped smoking a month ago and was smoking a small bowl almost daily a few time a day do you think I will pass my hair is long and I will be cutting a few inches off
June 16, 2019 @ 5:35 pm
I have no way of knowing if you will pass. But you’re using the most effective cleaning regiment for beating the test.
Would you please let us know how your results turned out? Your situation is very common…
June 14, 2019 @ 7:41 pm
I’ve been on hydrocodone for about 3 years or so because of a bad car accident. I am seen every month at a pain management clinic. I go through weeks without taking but 1 or so a day and then something might happen to make the pain worse. The past few months have been really bad and I was taking 6-7 a day (I’m prescribed 4xday). The other 2-3 were from the months prior when I didn’t need but 1 or so to get through the day. I just took a hair test and am worried they are going to say that I’ve been taking more than what I am prescribed. Can a hair test ACCURATELY tell the difference between somebody taking 40mg of hydrocodone and say 70mg a day?
June 16, 2019 @ 5:32 pm
That’s not what the hair test is designed to detect. It’s possible your employer could infer something from the test results, but the vast majority of labs only report whether you passed or failed and the average concentration for the entire 1.5″ hair sample (= 90 days of use). As long as you can produce a legal prescriptions for your hydrocodone and explain the recent pain problem, you’ll probably be OK.
June 20, 2019 @ 3:41 am
I smelled some bomb ass sh!t and haven’t smoked since ’10 if I take a hair test with out taking anything will I pass???
June 20, 2019 @ 5:24 pm
You are safe, don’t worry. You CAN NOT fail a hair drug test solely due to being exposed to second hand smoke. That’s a myth.
August 8, 2019 @ 8:45 pm
I stupidly smoked what I thought was marijuana only 2 weeks ago. But it had cocaine in it as well. I used cocaine at the beginning of the year but stopped. Until this incident happened. I’m trying to get a job driving semis. And I’m sure I’m gonna get my hair follicles tested for drugs. I still have 2 months til I get tested but I’m worried a lot. My hair is about 7 inches long. If I cut it short short and and let it grow out again to have it longer than the 1-2 inches they require will I be alright?
August 19, 2019 @ 9:05 pm
If you stopped using cocaine by April 30 and only used it once since, then your hair should test clean by late October (in 2 months).
To be safe, yeah, I’d cut my hair down so it’s no longer than 2″ at the time of the test.
Best of luck!
August 13, 2019 @ 5:03 am
I have been microdosing LSD off and on for the past few months. In the last two years I don’t believe I’ve taken any more than probably 10 hits total. The last time I took two hits was this past Friday 8 / 9 / 19. I’m going to possibly take a hair test in the next 2 to 3 weeks. Is there anything I can do to clean it out of my system or chemically strip any hair I have. I shave my head on a normal basis so I’m assuming they’re going to take armpit hair or body hair which I have a lot of. Please help.
August 19, 2019 @ 9:02 pm
Most employment hair drug tests do NOT test for LSD.
Unless your employer has specifically requested to test for LSD, then you’re probably safe.
August 15, 2019 @ 5:07 pm
I ingested through my mouth about $20 worth of cocaine two weeks ago, snorted very small line too. I ingested about $30 (same way through my mouth) about a week ago. That’s all I have used in years. I may have a hair follicle test in about 2-3 weeks. I have short hair about 1.5 inches. I’ve been sweating in a sauna and steam room regularly. Will I be dirty? What do you reccomend.
August 19, 2019 @ 8:57 pm
You will probably test clean, Bill. The hair test is designed to detect sustained drug use over time, not 1-2 uses.
August 17, 2019 @ 5:05 am
So after reading all the comments the only method that seemed to work is almost four years ago. It is now August 2019. As we all know detection technology only advances. So with that thought in mind, Is there anyone who had less than a week notice of a hair test and who was a daily user of whatever drug (legal or not) who has actually tried a cleansing/detox method before the test and passed?
August 19, 2019 @ 8:54 pm
Alixii, hair test lab technology hasn’t changed much at all in the past 5-10 years. The methods used are the same, the same equipment, same cutoff levels, etc. So 4-yr old hair cleaning methods still work.
Almost every hair test lab uses the same 2-step process to detect drugs and metabolites in a hair sample, as follows:
1. Part of the hair sample is screened using an immunosorbent process. Hair tests normally use the Enzyme-Linked Immunosorbent Assay (ELISA) process. Other methods include RIA, EMIT, CEDIA and Laminar Flow.
2. Hair samples that test positive in step 1 are tested again for confirmation using a spectrographic analysis. The leading methods include gas chromatography mass spectrometry (GC-MS), gas chromatography-mass spectrometry/mass spectrometry (GC-MS/MS), or liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). They all do essentially the same thing – burn/dissolve your hair and measure the gas or liquid for traces of chemicals.
Learn more about recent issues and advances in hair drug testing here (research study on Wiley.com)
August 20, 2019 @ 2:28 am
Thank you for your prompt response. I have been reading different articles over the internet and I’ve seen many say that your hair can detect a one or two time use, so I bought the old style Aloe toxin rid. If there is something detected in my hair it won’t be much, and it would only be cocaine as I’ve used pretty small amounts twice this month and haven’t used anything in years. I’d rather be safe than sorry, so I bought the shampoo. The Mancuso method seems a bit too much. Will the aloe toxin rid help clean my hair if there is a small level of cocaine or do you recomend I do the Mancuso method.
August 22, 2019 @ 1:16 am
Jay, thanks for all the awesome help.
I smoked weed for the last 10 years. I quit smoking on July 20th. On August 10th I smoked 1 joint with a friend. I have a opportunity for a new job that requires a hair follicle test. I can schedule my orientation when I want. I’m thinking of November 4th. I have blonde hair and a fast metabolism. Should I be ok by Nov 4th or should I postpone it till later? Thanks for your help.
August 28, 2019 @ 10:43 pm
I’d postpone until after the holidays (Thanksgiving), just to be sure. Long-term heavy users are the most challenging cases. Sometimes can take 140 days of abstinence to test clean.
Best of luck!
August 22, 2019 @ 7:38 pm
Also how soon do you recommend taking the hair follicle test after using the shampoo?
August 28, 2019 @ 10:41 pm
Use the shampoo the week of your test, right up through the night before you walk in.
August 23, 2019 @ 11:04 pm
I vaped marijuana 2-3 total times in June, 2-3 total times in July, and stopped on July 27th. when I “vape”, its usually only “2-3 hits”. I think I`m a light weight, because that usually gets me pretty good. I don`t smoke down a whole blunt or a bowl or anything by myself… HOWEVER, the hits are medical grade cartridge stuff.
I have so far done the macujo method 5 times, I believe I may be able to continue doing it for about another 1-2 weeks, which would put me at 12-19 total treatments and a little over 1.5 months clean at the time of guesstimated testing.
Think Ill be good buddy?
September 13, 2019 @ 10:40 pm
Sorry I didn’t reply in time – did you pass?
August 24, 2019 @ 5:17 pm
Hi JZ i had a surprise hair test sprung on me Tuesday and did the hair test late Friday afternoon. I had the aloe rid shipped here Thursday morning and used the mac method i think 5 times plus more aloe rid shampoos Friday morning and Ultra Clean before test. i have smoked only a few times the last year in many years. Each time only a few hits. The last time was around Aug 5th and just a.couple light hits. I did a cvc mj test and said neg. Also a cheap dollar tree test.said neg. Also drank 2 herbal clean 32 oz detox before test. They also wanted alcohol test which i had a.few mimosas a week before. Very infrequent light smoker and only a few times the last year and last time around 20 days ago. All i know is my head was burning pretty good from the 2 day mac treatment and.shampoos. I’m very nervous but think i will be ok but that physmedic is testing. Have a great job but more worried about passing both . like said both urinne test neg and little worried about alcohol. But if it strips thc i think strip alcohol.
October 3, 2019 @ 10:39 pm
Inquiring minds want to know: did you pass?
September 6, 2019 @ 3:45 pm
So basically, I took some 2-3 hits of a joint around May 14 and 3-4 hits of a bong (on two separate nights ) around July 28th.. If I have a hair test scheduled right around September 25th,will it be positive . . Note: not a regular user. Just a one time user…
September 9, 2019 @ 10:25 pm
One time users almost always pass the hair test. I wouldn’t stress over it – but don’t use any more!
September 12, 2019 @ 1:13 pm
I am in desperate need of help regarding a potential career. I used cocaine somewhat frequently over this past summer(every other weekend), the last time I used was July 7th. So I’m just curious how long do I need to wait until I shave my body completely, and I was going to cut my hair down to a #3. My hair test is in about 40- 50 days from now. I can postpone the test but if I do I would have to wait another 3 months before being hired. I wanted to see if I can make for the upcoming test or should I just play it safe and wait the extra 3 months? I really want the job so I just want to be sure, any help is appreciated.
September 20, 2019 @ 9:28 pm
I see your dilemma. Theoretically – if the lab tech does his/her job correctly – you should pass a 90-day look back hair test in 40-50 days. But just barely.
Obviously, the easy play is to delay 3 more months. But if you’re worried it might go away or something, then what you can do is cut your hair down to ~1″ all around your head and shave your armpits and body hair. They won’t be able to get a full 90-day sample of hair, but it might be enough for them to pass you.
If they don’t accept the shorter sample, then you can punt for 90 more days, until the next test.

If you use heavy up until the hair test but you’ve used the macula method along with the old style aloe rid shampoo and use the zydot ultra clean before test is it possible to pass
The hair test?

People do Macujo / Jerry G because they don’t really have another option and they want as much of a fighting chance as possible. It’s not guaranteed tho.
There are stories all over the internet from people who were saved by these two regimens.

I live in New Zealand and over here they test for drug use going back 2 years (hair length permitting). I smoked meth heavily for 2 years (daily) and once every couple of weeks this past year and a half. I am planning on leaving my partner in the coming months and applying for full custody of our son. I have been clean for 3 weeks now and since finding this website I am going to shave my head completely and stay clean. My question is are the testing processes the same in NZ as they are in the USA? I am willing to do whatever it takes to keep my son. His father is an addict and I know he won’t have this kind of preparation and knowledge going into the custody battle. Any advice you have will be greatly appreciated 😊
October 3, 2019 @ 9:09 pm
Testing processes are the same all over the world. So all the stuff you read here applies the same way.
Best of luck on your custody fight!

I do hair follicles every 6 months. My last one was August 30th. That same day I split 4 eight balls between 3 people. Every weekend it’s been 2-4 eight balls between the 3 people. My last use was this morning September 24th. My next hair follicle is due March, is it safe to say I’ll pass or a chance I can fail?
October 3, 2019 @ 9:07 pm
There’s def. a chance you will fail… time between last use and the next test is less than 6 months… on top of that, there’s a bit of lag time in hair growth to deal with. If I were you, I’d cut my hair down to 2-2.5″ all around the week before the test – and shave all of your body & armpit hair (or at least down to 1/4″ or so). It won’t be enough for a full 6-month lookback, but what they do get should be clean.
September 24, 2019 @ 7:00 pm
I smoked two hits July 27th. First time in years. I have a hair follicle test on 10/15. Will I be ok or should I start some sort of treatment?
October 3, 2019 @ 9:03 pm
Don’t worry about treating your hair – you should be fine.
September 24, 2019 @ 10:29 pm
I had hair test back in aug 23rd 2019…which was testing fir any use 90 days prior which I took one hit of meth…test came back negative…I haven’t used since then until sept23rd in a twelve or more hour period…will I pass my next test in November?
October 3, 2019 @ 9:02 pm
Yes, you will probably pass again. Crossing fingers…
September 29, 2019 @ 4:52 pm
I quit smoking pot in early April 2019, shaved my entire body.
July 3rd 2019 I took a 10 mg edible and smoked 1/4 gram of oil with friend.
First week of August 2019 had 2 hits for 5 days
Could have a Hair test for pre employment is in beginnning of October 2019.
Cut hair on my head down to 1 to 1 1/4″ light Brown strait.
Cut my body hair down to 1/2″.
Whats your thoughts about the possibility of not passing?
October 3, 2019 @ 8:51 pm
For a 90-day test you’re probably good to go (will pass).
October 3, 2019 @ 4:26 am
What if you take adderal once here and there in about 20mg dosages maybe 2 to 3 times a month about 40mg last month and have a hair test due in 2 months time? Will I be able to clear it just from abstaining?
October 3, 2019 @ 8:38 pm
Drug traces remain in your hair permanently, unless you strip them out using harsh detergents/chemicals/bleach – and even then, most of it will remain.
So abstaining for 2 months for a 90-day look back still leaves about 30 days of drug use in your hair sample.
November 8, 2019 @ 11:27 pm
What if you just need to pass for alcohol and you’ve stopped drinking for a month…will any shampoo work? I only see info about drugs..
November 20, 2019 @ 9:04 am
I have a hair follicle test any day now. My first time smoking is when i bought a .5g thc cart in mid April and i finished it late May. I took 5 hits on a friends thc cart mid june and 6 hits on july 7. Then on august 31 I took 10 hits off a cbd distillate cart from blacktiecbd.net. I am scared out of my mind that I will fail the hair test to keep my job and was thinking about buying the old style aloe toxin rid shampoo.
November 25, 2019 @ 6:53 pm
Hi Jay, I smoked daily last December till the end of January. It’s been nearly 10 months since i stopped cold turkey. I have a hair test in the end of the December. I usually hair my hair fairly short, what are my chances of passing?
November 28, 2019 @ 6:25 pm
Tom, you should def. pass cleanly. Best of luck!
November 26, 2019 @ 12:10 am
I had to take a hair follicle test today for court, was given no notice. My lawyer mentioned something about maybe getting one but that was 3 months ago. I did so much research and was going to do the macujo treatment, but then the test wasn’t mentioned again. I only did heroin 1 time 4 1/2 months ago. The test was 180 days not 90. I’m so scared I’m going to fail.
December 5, 2019 @ 4:05 am
Hi Jay Z,
I consumed for my first time ever THC. I ate half of a 10 mg THC cookie 60 days ago. I have a hair test in 5 days. Do you think I have any chance to pass it?
December 6, 2019 @ 6:31 pm
Lucy, you should pass with flying colors.
January 22, 2020 @ 5:36 pm
First question of 2020!!
Hey Jay Z, I’ve been a heavy smoker for all of 2019. Have a possible hair test in March or April. I stopped smoking on January 1st and haven’t since. Bought a 5 day detox and did a urine test and I passed! So I’m wondering is it ok to shave my head now? I’m thinking all the new hair that will grow will be clean since I passed a urine test.
Thanks in advance for your help! This site is fantastic!!!
January 25, 2020 @ 11:27 pm
Don, if you tested clean on a urine test, that means your blood levels are below the cutoff. Which is good, but it takes about a week for tainted hair to grow through your scalp enough to be cut off.
In other words: make sure you don’t shave until at least a week after your test. I’d also shave my body hair and underarms right before the hair test date, because you probably won’t have a full head to sample by then.
January 23, 2020 @ 5:59 am
Hey Jay –
I smoked 3-4 hits of a blunt with my now-ex back on December 4, 2019. I also did 3 hits of one once in Mid-November 2019. Wasn’t even enough for me to feel any effects of it. Otherwise, I haven’t smoked marijuana in 15 years (and even then it was only 1-2x back then). I am now due for a drug test for a new job next week (~Jan 27). Will this show up in a hair test if that is the route they go for the test? I would be so bummed if my few hits for the first time in years and years screwed me over now.
If I got my hair dyed at a salon this weekend (I have 3-4” of gray on top of my 30 year old head I want to cover anyway), would that make a difference just in case either?
January 25, 2020 @ 11:24 pm
Pippy, you should test clean. That’s not enough use to register. Good luck on your test!
January 23, 2020 @ 6:45 pm
If one stopped smoking from October 13th to January 5th, resumed smoking from the 5th-10th(a couple bowls a day), stops for three days, resumed from the 14th-20th(2 bowls per day), then stops smoking altogether from that point on(21st-?)….starts applying for jobs in an industry where the likelihood of a hair test is likely, what would you say is the best method/shampoo product to use for passing such a test?
How prominent do you think the thc will be within their system? A home urine test was used after stoping for 3 days and it came back negative…I know that doesn’t affect thc within the follicles, but urine and saliva test wise, I’d think one would be able to pass those, it’s just the hair test that’s most worrisome. Any advice would be appreciated JayZ….thanks 😎
January 25, 2020 @ 11:23 pm
Such a person would very likely fail a hair drug test if administered within the next 100 days.
Recommend Macujo or Jerry G cleaning regimens for this person. See this page to learn more: THC Detox: 2 Ways To Clean Your Hair.
January 26, 2020 @ 4:19 am
If someone takes four little bumps of cocaine how long does it take to get out of your system and hair
January 28, 2020 @ 11:16 pm
4 bumps probably won’t ever register on a hair test.
For blood and urine tests, give yourself a week.
January 28, 2020 @ 5:12 pm
Hey Jay Z, I was a heavy smoker up until January 3rd,2020, smoking 2.5 in a blunt, maybe a 1.0 at times. I have an opportunity to be a truck driver and would like to start soon as, I overstand that my urine has to be cleaned for 30days,which is in a few days, but my main concern is the hair test they require. My hair is 9″-10″ and cutting it is honestly my last resort if possible. I read almost everyone comment and your response since I know little about the two treatments but in my case, being that I have no real dead line date but as I mentioned would like to start soon as I can, what would you recommend because I’m still kind of confused as to: (A) can I just take the regime WITHOUT cutting my hair being my hair is 10″? (B) once I take the regime will I be “hair drug free” forever AS LONG AS I DON’T SMOKE even when my hair continues to grow being that I’m 25 days clean? (C) which regime you prefer that I do take? (D) is it a certain day I should treat my hair, or once I treat is its clean for good?
February 1, 2020 @ 11:10 pm
(A) Yes, you can just use the cleaning regime without cutting your hair. I always recommend cutting it tho if you can, because it eliminates any chances of failing if the lab tech take the wrong cut of hair for the sample.
(B) NO, you need to use the cleaning regime every day for at least a week, up to the day of your test. Don’t clean your hair and then let it grow for a week or two. Remember: fresh hair continues to grow through your scalp, so you need to keep treating the new growth.
(C) Macujo is easier on your hair, so most people with long hair choose that one. Jerry G is cheaper, but much harsher on the hair due to bleaching.
(D) Clean your hair for at least a week… through and up to the day of your test.
February 3, 2020 @ 8:36 pm
ive smoked alot of marijuana for about 3 months including wax ive stopped smoking for about 3 weeks, how much longer till my i can pass the hair follicle test
February 4, 2020 @ 10:56 pm
Israel, For a heavy user, it’s best to wait at least 120 days since your last use before taking a 90-day hair test. Also recommended that you cut your hair down to 1.5″ all over and shave your body hair/armpits to cover all the risk.
March 22, 2020 @ 3:58 am
Hey Jay Z,
If I stopped smoking the first week of December of 2019 and have a hair follicle test coming up (I think) in April, do you think I will pass? I smoked about every other day and usually less than a gram each time. Or I would just smoke a blunt with friends. I’m a female and my hair is a little passed my shoulders.
March 27, 2020 @ 6:43 pm
You should pass for a 90-day hair test if the test is after mid-April. That said, your timeframe is close – so the result also depends on how well the lab tech cuts your hair sample. If she doesn’t cut 1.5″ exactly from the scalpline-up, then it could grab some older hair. In which case you would be at risk.
Recommend doing Macujo the week before your test, once a day right through the day before your test.
