Hair Drug Test In Your Future?

scared of drug test

You’ve come to the right place.

On this site you’ll find the latest information about the hair follicle drug test – and four ways to beat it.

This site was built for mobile devices. If you have a comment or a question, please leave it for me at the bottom of the page.


What Would You Like To Know?


Hair Drug Tests Are Now the Norm

In the US, the hair follicle drug test is gaining favor over older and more frequently used urine and blood tests for three reasons:

  1. 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.
  2. 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.
  3. Older tests are losing effectiveness: urine testing has become less reliable due to the proliferation of cheat products like synthetic urine and powders.

In fact, Occupational, Health and Safety magazine recently recommended that HR 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).

bad mobile design

See anything wrong here??

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 Follicle Drug Test Works

The reason a hair follicle test works is simple: your hair needs blood to grow, and it gets that blood via the root of the hair follicle.

Hair Follicle Drug Test

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.

↑ BACK TO TOP

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.

Sample of Hair Taken During Hair Drug Test

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 3 days.

↑ BACK TO TOP


Which Drugs Are Detected By A Hair Follicle 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 Cut-Off Level Detection
Alcohol N/A 90 days
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)
  • Inhalants
  • 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, it is possible that a hair test will 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.

↑ BACK TO TOP


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 hair on your head. The table below explains the drug test limitations of each source of hair.

Source      Limitations of Sample Detection
Head
  • Hair dyes, bleaches & treatments affect results.
1 cm=1 mo.
up to 1 year
Arm

  • can only be used to prove abstinence.
  • can’t confirm excessive use due to contamination.

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. The drug tests have flaws.

In fact, 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 will be 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.

Four Ways To Beat a Hair Follicle Drug Test

  1. Shave It All Off

  2. Do-It-Yourself Detox

  3. Detox Products That Work

  4. Personalized Detox Program

Burnett's_Cocaine_for_the_hair_(advertisement,_McClure's_1896)

   tip: avoid this product 😉

OK, so this is where the controversy begins.

First I’ll start with the proverbial caveat: there is no single method or product that can guarantee you’ll pass a hair drug test. None.

That said, there are a few methods, products and services that can help. 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. Shave It All Off

Mr Clean

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 5 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 7 days for new hair to make it up to the scalp/skin line.

Simple, right?

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 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.

2. Do-It-Yourself Detox

passed a hair drug test with this

One Guy’s Solution

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 Growman/Macujo method uses salicytic acid and vinegar, and the Jerry G method uses bleach.

There’s a lot of debate as to whether these two methods work that well.

Most doctors say they don’t.

Hundreds of users say they do.

In many cases, people supplement a home remedy with special detox shampoos and/or detox body flushes/drinks.

↑ BACK TO TOP

3. Use Detox Products That Work

Purchasing a detoxifying product to rid your hair of drug traces before the test is the easiest path, so a lot of people choose this route.

Problem is, there are lots of products 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 products I found that really seem to work.

Detox Shampoos

Washing 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 the drug traces live.

As is true with any powerful over-the-counter remedy, the stuff that really 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.

Aloe Rid by Nexus (old formula)

aloe rid detoxifierAloe Rid Shampoo (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 (barcode number: 05592 16035) works.

TestClear still sells the old formula. But they are in short supply, and it isn’t cheap.

 WARNING  Don’t buy the old formula anywhere else! 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.

The 5 Best Detox Shampoos Selling Today

Here are the five best-rated and most frequently mentioned detox shampoos for passing a hair drug test. Nexus Aloe Rid is by far the most recommended.

Please note: none of the products above are FDA-tested and approved for beating a hair drug test.

4. Personalized Detox Program

If you are still unsure about how to proceed, then you can hire a personal detox counselor to walk you through a cleansing process that matches your specific situation.

Hair Detox Friend

The most reputable detox program I know of is Hair Detox FriendTheir team has more than 10 years of experience helping people pass drug tests.

Hair Detox Friend provides you with specially formulated products and a custom-tailored program to cleanse your hair of toxins – plus a personal consultant to talk with.

For a hands-on consulting program, the price is extremely reasonable (less than $50). They also offer a 60-day 100% money-back guarantee.

      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 bought get clean shampoo and ultra cleanse shampoo and conditioner and to me, the directions are not too clear. I’m under the assumption I wet hair and use ultra cleanse, leaving in for 5min, rinsing and then reapwating again. Then drying and then using get clean shampoo, beginning with dry hair, leaving in 30 min 2x each massaging with a shower cap then drying (No rinsing). Im supposed to do this the day of. Correct? NEXT question is I’m using these products day of interview just in case I get sent for testing that day. What if I get sent next week? Will my hair still be free of toxins considering I still won’t be using any drugs? Or will my regular shampoo strip away the stripping agents? HELP!

      Hey SmurfJZ,

      Because your hair continuously grows from your scalp, it’s always best to use detox shampoos right up to, including the morning of, the test. The chances they will cut your hair right at the scalp line is small, but it is possible.

      If you need to strip THC metabolites from of your hair, then here are the two most popular cleaning methods – both rely on more than shampoo to do the job:

      Smoking and snorting produce the same effect on a hair drug test. That’s because cocaine gets into the hair through the bloodstream. Doesn’t matter how you ingested it.

I had bleached three times and put a toner and did the macujo method twice prior to a test I took on my own… I failed. I bleached two more times toned two more times then went to the salon and had corrective die put on.. I passed

      If you stop smoking, then shave everything off, then not smoke again until after your test, then you should be good to go.

      Just make sure you wait until 7 days after your last smoke to shave (because it takes that long for tainted hair to reach the surface of your skin).

        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.

          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.

            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.

      Emily,

      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!

      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.

          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.

      Rob,

      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!

    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.

      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.

    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?

      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.

    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.

      Ben,

      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 occasional marijuana use (or single event usage), at the 50 ng/mL cutoff level, it would be unusual for the detection of cannabinoids in urine to extend beyond 3-4 days following the smoking episode.

      For Chronic/Frequent users: 10 days

      “Based upon recent scientific evidence, at the 50 ng/mL cutoff concentration for the detection of cannabinoids in urine, it would be unlikely for a chronic user to produce a positive urine drug test result for longer than 10 days after the last smoking episode.

      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

    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.

      Ward,

      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.

      Good luck,

      JZ

    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!

      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!

        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.

    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?

      Amanda,

      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,

      JZ

    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!

      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.

    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

      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…

      DJ,

      Good question!

      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.

      Good luck!

    Thanks so much for your informitive website. I have a general question that I can’t find the answer to online.

    Reply

    • Jay Z.
      June 5, 2015 @ 10:45 pm

      Jim,

      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.

      So…

      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,

      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.

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.

      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).

      Good luck!

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?

      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.

      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.

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.

      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.

    Jay Z,
    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?

      Brittany,

      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.

      Good luck!

      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.

    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

    Reply

    • Jay Z.
      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,

    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:
      – Amoxicillin
      – Ampicillin
      – Coca tea, Coca leaf, Coca flour, Coca oil (all banned in the US)
      – Diabetes
      – Kidney disease
      – Tonic water (a LOT of it)

      I sure hope you squeak through!

      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.

    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!!!!!!

      For Macujo, Aloe Rid is just one of the ingredients – you need the other ingredients, too.

    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?

      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,

        Hello brothers!
        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..

      Reyni,

      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!

      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.

      Good luck!

    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.

      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.

      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,

    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?

      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.

      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!

      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.

      USDTL - Drugs Detected in Standard Hair Strand Tests

      (ref: US Drug Laboratories website)

      For cheaper tests like 5-panel or 7-panel screens, Suboxone is not one of the drugs included.

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″?

    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.

      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.

    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?

    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.

      Baxter,

      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:

      JWH-073
      JWH-250
      JWH-081
      JWH-018
      JWH-210
      JWH-019
      AM-1220
      MMB-CHMINACA
      AB-PINACA
      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.

      Good luck!

      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.

      Take care,

    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.

      Sonja,

      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!

    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?

      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.

    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?

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!!!

      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).

    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.

    Mr. Z,

    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?

      Matt,

      Great question.

      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.

      Good luck,

    Hello, JZ
    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

      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.

      These include:

      Amoxicillin
      Topical anesthetics derived from cocaine (does not include lidocaine or novocaine)
      Liver disease
      Kidney disease
      Diabetes

      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.

      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: http://hairfollicledrugtest.info/thc-detox-clean-hair-home-remedies/

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).

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.

    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.

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.

    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?

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.

    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?

      You’ll probably be OK. A single use is usually not detectable on a hair test.

    Hello,

    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.

    THANKS!!

      Celine,

      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.

      Good luck!

    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!!

      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.

    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?

      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!

    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.

      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.

    Hello Jay,
    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.

      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.

      Good luck!

    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.

    In the charts what do you mean by cutoff level?

    • Jay Z.
      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.

    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?

      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.

    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.

      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!

    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?

      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.

    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

      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.

    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.

      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.

    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.

      Wayne,

      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.

    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.

      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!
