Two Home Remedies to Clean THC From Your Hair

welcome to colorful colorado

Sooo… marijuana is now a legal drug in my home state of Colorado.

But Coloradans can still get fired for smoking pot, because THC remains on the list of banned substances for the vast majority of companies here. Marijuana also remains on the list of drugs detectable by the hair drug test.

And THC stays in your hair a looong time.

So if you have a hair drug test coming up – even if you live in Washington or Colorado – you still need a way to get traces of THC out of our hair.

The good news is that there are two proven THC detox procedures that can help you pass your next hair drug test.


What Would You Like To Know?

Use this Table of Contents to jump straight to the topic you’re most interested in.


How THC Gets Into Your Hair

I will be quick here, but it’s important to understand what’s going on when you smoke marijuana & what labs are actually testing for to understand why certain cleaning regimens work and others don’t.

First thing you need to know:  the hair drug test doesn’t test for the presence of THC (∆9-tetrahydrocannabinol).

Instead, test labs are looking for minute concentrations (50 ng/mL) of THC-COOH (11-nor-9-carboxy-THC) in your hair sample.

THC-COOH is a metabolite (byproduct) that’s created when THC is broken down in your body.

THC-COOH gets into your hair in two ways:

  1. most of it is deposited onto the hair shaft by your sweat glands.
  2. some of it gets through your bloodstream into the hair follicle.

A lot of people think it’s just one or the other. You see a lot of religious debate online about this.

This research graphic below shows the many ways THC and THC-COOH get into and onto your hair (courtesy of Nature.com).

Keep in mind that the hair test only detects the TCH-COOH metabolite, not THC nor the other cannabinoid shown in the graphic.

In this diagram, note that THC can be deposited onto your hair through contamination and second-hand smoking, but THC-COOH can only be transmitted to your hair after first passing through your blood.

If TCH-COOH got into your bloodstream, then it proves that you ingested or inhaled a THC product.

This is why labs test for the byproduct, and not THC itself.

Cleaning your hair with strong chemicals and shampoos removes the portion of TCH-COOH that is deposited by your sweat glands onto the surface of your hair.


Your Best Plan of Action

OK enough of the science.

Since this is a mobile site, I’ll get right to the point.

Here is the most proven plan for stripping THC (THC-COOH) out of your hair:

The Best THC Detox Plan for a Hair Drug Test

If you want to remove traces of THC from your hair prior to a hair drug test, then your best plan of action is to do the following:

  1. Use either the Macujo or Jerry G method to clean your hair.
  2. Clean your hair several times during the week leading up to your test.
  3. The night before and the morning of your drug test, wash your hair using one of the recommended shampoos in the table below.
  4. Drink plenty of fluids during the 24 hours leading up to your test, in case the lab decides to test your urine, too.
  5. Add a supplement or herbal, if you want.
  6. Don’t waste your money on THC detox drinks – unless you’re worried about the urine test, too.

Two THC Detox Procedures You Can Do At Home

Hundreds of people swear that two home remedies – the Jerry G method and the Macujo/Growman method – will strip THC metabolites from your hair and help you pass the hair drug test.

Both are pretty simple. But they rely on harsh chemicals, so they’re hard on your hair.

But, you ask: do they work?

As you might expect, drug test labs say they do not.

On the other hand, there are hundreds of people who claim they absolutely doLike this guy,  this young man,  this happy person  and  this fine lady.

I’ll leave it to you to decide who you trust.


The Macujo Method

vinegar clean and clear and Tide

The Macujo cleaning procedure was first described on Marijuana.com in the early 2000s.

In 2007, a Grasscity.com user named Growman talked about his success and the Macujo method accelerated in popularity.

Macujo/Growman is the most frequently discussed THC home remedy on forums and social networks like Reddit.

The Macujo process deep-cleans your hair using an older formula of Aloe Rid shampoo; acetic acid (vinegar); salicylic acid shampoo; and laundry detergent.

The Macujo/Growman method clearly works for many people, but it’s hard on your hair and may chemically irritate your scalp.

Supplies

aloe toxin rid shampoo-150x300

 TIP:  Don’t buy the ‘old formula’ on Amazon. People have paid lots of money for it, but received the new formula instead (WHICH DOES NOT WORK).  Check the 1-star reviews on Amazon to see what I mean.  
  • Salicylic acid shampoo like Clean and Clear pink (2% Salicylic Acid) or Neutrogena T/Sal (3%).
  • Tide detergent: liquid form, available at any grocery store
  • Heinz vinegar: available at any grocery store
  • Shower caps: buy at least a dozen
  • Goggles: to keep your eyes from burning
Directions

Follow the cleaning procedure detailed below at least 5 times over the 3 days prior to your hair drug test.

Choose a deep sink where you can rinse your hair thoroughly with LOTS of warm water.

  1. Wet your hair thoroughly with warm water.
  2. Pour Heinz vinegar on your head and massage it into your hair all the way down to the scalp. Keep the vinegar away from your eyes – it will burn like hell.
  3. Put the goggles on. Pour a dollop of Clean and Clear Pink or Neutrogena into your hand and massage it into your hair. This will probably burn your scalp a bit. Wipe and clean all exposed skin – especially your ears, eyebrows and forehead.
  4. Put a shower cap on your head and let it sit for 30 minutes. Keep a wet towel handy to wipe away any Clean and Clear that drips out of the shower cap. You’ll look really dumb at this point, so take a selfie for posterity.
  5. Remove the shower cap & rinse your hair thoroughly.
  6. Wash & rinse your hair twice with Aloe Toxin Rid shampoo.
  7. Place a very small amount of Tide into your hair to finish wash everything out. Use lots of warm water to rinse. Keep rinsing until your hair squeaks like you’ve never experienced before.

Note: this procedure is hard on your hair and will remove all essential oils. You may want to follow with a conditioner, but wait at least an hour before doing that.

The Jerry G Method

In 2008, a user named “Jerry_G” started a thread on Cannabis.com discussing a new bleach-and-clean method he claimed was “90% effective” against the hair follicle drug test.

According to Jerry G, the method works because bleaching opens up the hair cuticles, making the metabolites easier to clean – as depicted in the graphic below:

how bleaching hair impacts the hair cuticle

Since his original post, many people have backed Jerry’s claim that this is one of – if not the – most effective way to strip THC metabolites out of your hair.

The main downside of this method is that repetitive bleaching destroys your hair. This is probably why the Macujo method is preferred.

Supplies

toxin wash    zydot_ultra_clean_shampoo

Directions

The process is simple: bleach and re-dye your hair, twice.

Note: your hair will get damaged. A lot of people cut their hair after this procedure.

  1. Perform the first bleach-and-dye on the day you quit using. Ask your hairdresser (or a fake blonde friend) how to bleach your hair properly using peroxide. For the re-dye, just follow instructions on the package.
  2. The second bleach-and-dye should be done at least 10 days after your last use of marijuana. If you have little or no time, then the second bleach and redye should be done as close to the test as possible.
  3. On the day of the test, make a thick baking soda paste w/ water and massage it into your hair. Then, do a full Toxin Wash treatment followed by a full Zydot treatment. Some people do step this several times.

Which THC Detox Products Really Work?

One Guy’s Solution: Do Both!

Many people who use the Macujo and Jerry G methods also use products like shampoos, detox drinks and supplements to give themselves a little extra luck.

Listed below are the products that seem to work – and don’t work – for the hair test, based on my research of forums, discussion boards, friends and customer ratings online.

Detox Shampoos

Some detox shampoos really seem to work for a large number of marijuana users.

I say some, because a whole lot of so-called detox shampoos aren’t any different than the shampoos you use every day. They just carry a different label.

The best-known THC detox shampoo is Aloe Rid  – but only the old formula (Aloe Toxin Rid). It’s expensive as hell, but worth it.

old style nexxus aloe rid

To help you sort through the rest, I studied the successes of real pot smokers documented on popular weed forums including hightimes.com, cannabis.com and grasscity.com.

In addition, I went through hundreds of user reviews posted on popular drugstore and retail sites like TestClear.com, Drugstore.com, Amazon.com, Walmart.com and more.

In the end, I narrowed the list of shampoos down to a few who meet the following two criteria:

  1. there are multiple independent claims of passing a hair drug test due solely to this product.
  2. the shampoo is rated three stars or better on popular retail and drug testing websites

↑ BACK TO TOP

Detox Drinks

best thc detox drinks

Detox drinks are popular with pot smokers. There are dozens of examples online of people who claim a detox drink saved the day.

Almost all of these examples involved urine or saliva tests.

But the question I am trying to answer on this site is: do detox drinks work for the hair drug test?

After hours of researching online, I found no direct evidence that detox drinks helped anyone pass a hair drug test.

There are plenty of examples of people using the Macujo or Jerry G method and then finishing them off w/ a detox drink.

But I couldn’t find a single example where a detox drink was the only thing used to beat the test.

This actually makes sense, because the main benefit of consuming a detox drink is that your body fluids are diluted with water and the THC is masked in your body fluids.

But hair isn’t a body fluid.

Enough said: do not rely on detox drinks to save your job.

↑ BACK TO TOP

Food Supplements and Pills

A third type of THC detox product used by many marijuana users is consumables. This includes food supplements, herbs and pills.

My research revealed a lot of conflicting information.

On one hand, all of the product manufacturers claim their products work and some provide clinical evidence to prove it. Many offer money-back guarantees, too.

On the other hand, I found almost no claims from people consumed one of these products (only) and successfully passed a hair drug test due to that product.

I’m not saying consumables don’t work. I’m just saying that I can’t find independent examples of people saying the use of just that product caused them to beat the hair drug test.  If you know of any direct evidence that a particular product worked on a hair drug test, then please leave a comment below so we can share it!

As with detox drinks, you’ll find plenty of people who add supplements to their Macujo and Jerry G cleaning regimen.

My take on consumables right now: most of these products are safe and organic, so you don’t have much to lose by adding them to your regimen. If you think a supplement will help, then go ahead and take it.

But I wouldn’t rely on consumables alone to save your neck, m-k?

Best of luck on your next hair test!

          A 90-day look back is the standard, but yes, there are tests that go back a year.

          The results of a 12-month hair tests can be easily challenged, though, because all sorts of things can contaminate hair over that long a timeframe. Bleaching, hair coloring, stress on hair can all impact the results.

            I have almost a month before I will get tested because I have to wait two weeks on my prescription glasses and then another week or or two before I can schedule an appointment. This is a one year hair follicle test. I smoked a joint three times split between three people approximately 5-6 months ago. My hair on my head is currently am 1/8th of an inch. Do you think I should do Nair or some other product on 100% of my body?

          • Jay Z
            July 18, 2017 @ 4:11 pm

            When you walk into the test in a month, you will only have about 1/2-3/4″ of hair on your head, so there’s no way they can see back 1 year. More like 3-5 months.

            So, they may want to sample your body hair, instead.

            Given your use, if you don’t want ANY risk of failing, then you should probably Nair / shave all of your body hair off, right before the test.

            Good luck!

            Jean, if you take Vicodin for anxiety, then bring your doctor’s prescription with you.

            I don’t know what kind of job you have applied for, but some employers will give you a pass, if your doctor prescribed the opioid.

            But it also depends on the concentration they find in your hair. If you’ve been abusing Vicodin, then you are going to fail the test (most likely).

            Best of luck on your test!

        Hi Jay. I work as a temp to hire and had to go through a drug screen by mouth and urine. I cleaned out by using Cleasing Formula from GNC. I passed both, but my concern is when I get hired permanent, I will have to do a hair folicle test. I know my urine is clean and I haven’t smoked in about a month. I drink plenty of water at work, but is a month long enough for my hair to be clean. I haven’t been scheduled for the test yet, but just in case, what would you suggest? Also, I keep my head clean shaven.

          BT,

          No, a month of abstinence is not enough time to grow enough clean hair to pass a 90-day hair sample test.

          A moderate user needs about 110 days of abstinence to guarantee his/her hair sample is clean.

          If you shave your head, then they will likely try to sample your underarm, arm or chest hair, if any exists. The risk of failure is higher if they do this, because body hair grows more slowly than head hair.

      They’ll take a sample from another part of your body.

      First, they try taking a sample from under your arms or from your chest (if a man). If they can’t do that, then they’ll sample your pubic hair. If nothing down there, then they may ask for urine or blood. They may decide to fail you if they think you only recently shaved to avoid testing positive.

      If they fail you, don’t just take it. Raise hell and ask for a retest using your urine, blood or defer until later.

      Good luck!

      tin,

      The Nexxus Aloe Rid (old formula) shampoo is just one ingredient of several used in the Macujo/Growman method. Click this link to read about Macujo/Growman.

      If you keep using drugs, then no shampoo can strip your hair “for good”. This is because your body will keep growing new tainted hair beyond the scalp line that contain traces of more recent drug use. If you plan to keep using, then you’ll need to do another Macujo/Growman or another cleaning procedure before every test.

      Best strategy for passing is to stop using 100 days before the hair test, then cut your hair down to 1.5″, all around the head, a few days before the test.

      Of course, not everyone has the luxury of 100 days advance notice. This is why I put this site up…

      Best of luck on your test,

      If you have 90 days to spare (how unusually nice of them!), then I strongly recommend that you just stop using, like today.

      90-100 days of abstinence is the most predictable/controllable way to pass a hair drug test. The remedies discussed on this site are for people who don’t have that much time (since last use).

      Good luck!

    I want to apply for my dream job but they do hair tests. I went to WA for a few months the end of last year and joined all the group’s in celebrating the new law. I haven’t smoked mj for months now. But, I’ve read the test go back a year? I don’t know what to do.

      Freaked Out,

      Don’t be.

      If you only used MJ a few times in December, then by now you are clean for the test – assuming they test for the past 90 days (the first 1.5″ of hair from your scalp), which is the norm.

      In other words: CAN they test further back than 90 days? Sure. WILL they? Probably not.

      The vast majority of hair tests only look back 90 days. On rare occasions (government/defense jobs for example), they test further back. Part of the reason for this is that the accuracy of the hair test degrades over time as natural weathering, shampoos and chemicals damage your hair follicle. The labs know this.

      Yes, Nexxus Aloe Rid shampoo (old formula) is expensive. But it’s by far the most recommended THC detox shampoo used as part of the Macujo method, described above.

      Best of luck snagging that dream job!

    Please advise,

    4. Put a shower cap on your head and let Neutrogena sit for 30 minutes. Keep a wet towel handy to wipe away any Clean and Clear that drips out of the shower cap.

    5. Remove the shower cap.

    (Am I to assume I rinse the neutrogena out before I put in Nexus or do I add Nexus in with the Neutrogena?)

    6. Wash & rinse your hair twice with Nexus Aloe Rid shampoo.

    I haven’t touched a drug in 6 years, that is, except 2 drags of weed about 6 weeks ago. Go figure, I have my dream job waiting for me…if I can pass the hair test… Can that small of an amount be picked up? Is there anything that could cause a false THC positive? Help!!

      June 15, 2015 @ 12:42 pm

      Yes, even small traces can be captured in the hair follicle.

      But… if you only had 2 drags total in the last few months+, then your blood level may not have ever reached the minimum threshold. If that’s true, then you are clean for the test. This is impossible for us to know, though, without knowing the specific concentration of THC you ingested.

      Re. false positives:

      Because the hair test is looking for a metabolite (THC-COOH) that is specific to THC, there aren’t many chemicals/products that can cause a false positive for marijuana. Two things known to cause a false positive include:
      – the common prescription medication, Protonix (pantoprazole sodium), warns of “false positives” for cannabis on its label
      – hemp food products and oils

      Some people also claim ibuprofen causes false positives, but that has not been definitively proven.

      Best of luck on your test!

    I just bought the nexxus aloe rid shampoo that comes with Ultra clean shampoo.

    Do I still need to get the salicylic acid shampoo like Clean and Clear pink (2% Salicylic Acid) or Neutrogena T/Sal (3%)?
    Or does the Ultra clean shampoo take its place?

      It may be available somewhere else online, but I’ve not been able to find another source.

          Out of your blood, yes – but NOT out of your hair.

          Once drug traces get into your hair from drug-tainted blood, they will remain trapped in your hair at that level, even after your blood levels drop back down.

          Unless you strip the traces out.

          This ‘permanent record’ nature is exactly why employers use the hair test.

          Doesn’t matter what type of drug you used… once it’s in your hair, it stays there until you either strip it out or cut it off.

          For all drugs other than THC, you should abstain for 100 days then cut your hair down to 1.5″ right before your test.

          For THC, extend your abstinence to 110-120 days to allow for THC’s slower decline in blood levels.

            The hair test works exactly the same for all drugs – you need 100-120 days of abstinence to be certain.

            The Macujo and Jerry G methods may or may not work for Adderall. I’ve seen evidence it works for meth, but not a lot. Kind of uncharted territory.

            If it were me – and I needed the job or if it was a custody case – then I’d try one of these.

    Hi

    I have an upcoming drug test for a big job but im a little sceptical about doing the macujo method on my hair.
    Does it completely destroy my hair if i perform it? What will I look like? Will it be obvious to my potential employer that Ive done something to my hair?

    ps Has anyone else noticed itching of their scalp since they started smoking weed? Is this normal? and will macujo resolve this as well?

    This is my 3rd attempt at a post, and each one is getting shorter and shorter ha.

    I last smoked August 1st. I may be getting a job offer from a govt job. My hair is about an inch or so all around (had it cut earlier today after reading your post). Do you think I am clear? My test may be in about 2 weeks or more.

    If I want to do a home test to confirm I am clean (since its been over 90 days), which one do you recommend? What about finding a testing center in the Atlanta GA area?

    Thanks!

      Re. whether you will be clear by Dec 3:

      Given the info you shared, I think your chances of passing are pretty good if you were a light/moderate (weekly, not daily) smoker before quitting.

      Here’s why I say this:

      – you cut your hair down to 1″ (60 days of growth) on Nov 20, after abstaining for 100 days.
      – this means you had 33 days to clear your bloodstream before the oldest hair on your head today began growing (40 days minus 7 days for hair to grow through scalp)
      – 33 days is plenty enough time for a moderate user to clear their bloodstream of THC-COOH, the THC metabolite the labs test for.

      If you were a daily/heavy user, then your chances are probably still pretty good. Testing yourself at home is a great idea, though.

      Re. at-home hair tests: see the table of hair tests on our home page https://hairfollicledrugtest.info . Hair Confirm and Psychemedic sell very dependable & accurate home tests.

      Good luck on your test!

      Vinny,

      Yes, it will help.

      But you don’t have enough time to grow the minimum 1.5″ for a lab sample. Hopefully, they will accept a shorter sample.

      Be aware that if you’re a habitual user, it can take 10 days for your blood levels to drop below the minimum threshold, plus another 7 days for the last bit of tainted hair to grow through your skin. So, don’t shave until 2-2.5 weeks after your last use.

      Best of luck,

      If you regularly smoke more than once every 90 days, then you are definitely running a risk of failing the test w/ 3.5″ of hair and only 6 weeks between last use and the test.

        For some reason my comments aren’t showing up, so ill try a reply.. Amazon sells the nexus aloe rid shampoo, claims it to be the original formula.. it looks exactly the same as the one on the test clear website.. however the reported serial number is 605592 16035 6….. this differs from the one on the test clear website simply by the 6 in the beginning and end. Do you think it is a scam and is not in fact the original formula?
        http://www.amazon.com/gp/product/B000JO6B3M?keywords=nexus%20aloe%20rid%20shampoo&qid=1450260909&ref_=sr_1_1&sr=8-1
        I have stopped smoking about a month ago, system is probably clean so i was planning to start the growman method in the next month or so, as i haven’t gotten the job yet, but i know they follicle test, so i wanted to be ready… but i can’t help but wonder if amazon is selling the real stuff or a scam.

          I don’t really know the answer to that. But if you read the 1-star reviews of the product being sold on Amazon, there are complaints about the shampoo not working and/or not being the original formula.

          The only place I know that definitely sells the old formula is TestClear.

    My boyfriend has a hair follicle test sometime in January, maybe towards the beginning of February. We stopped smoking last weekend. His hair is at a 1/2in. right now. We plan on cutting his hair every 2 weeks. Will that be good enough or will we need to try one of the remedies?

      December 22, 2015 @ 9:45 pm

      Val,

      No, sorry, but cutting your hair every 2 weeks won’t be enough.

      At the time of your bf’s test, the sample station/lab expects to clip a 1.5″ long sample of hair from his scalp line. This will contain a record of his most recent 90 days of drug use.

      Given the short amount of time between his quitting and being tested (~4-6 weeks), a 1.5″ sample will probably contain evidence of drug use.

      The only way to get around the remedies is to cut his hair down to <0.5" in length ALL OVER HIS HEAD, right before the test.

      The problem with that approach is that the lab may not accept such a short sample and he may be failed for tampering (esp. if his hair is usually much longer).

      I don't want to tell you what to do. But your bf's situation is exactly why the Macujo and Growman methods were developed 😉

      Best of luck!

    You won’t test positive due to second-hand exposure. The only risk you have is your use ~5 mos ago.

    There are 2 ways to reduce your risk of failing:

    1. Cut your head hair down to about 5 months of growth (2.5″ of hair length) & hope they accept the slightly shorter length.

    2. Try one of the cleaning regimens described on this page: https://hairfollicledrugtest.info/thc-detox-clean-hair-home-remedies/

    Of the two options above, option #1. is the more reliable bet.

      Less certain, but given that THC is the hardest drug to scrub from your system, it’s probably worth a try.

      Remember, abstaining from use and cutting your hair far ahead of your test is always the best bet. The cleaning regimens are for people who don’t have that option.

They just notified our whole department that our contract is not going to be re-newed. Within 30 days they want us all to re-apply to the world wide company and be full time employee’s which is great. Except that the re-hire comes with a hair drug test. I need to pass this test. . . would cutting my hair after 15 days be worth it? Could a heavy user pass with just a shampoo or do i need to do the full JERRY G method?

      Cutting your hair within 15 days of last use AND within 15-30 days of your hair test isn’t a good bet if you are a heavy user.

      Any hair that has been treated w/ Macujo remains clean, but new growth has not been treated so it will be as nature grew it.

      If you haven’t used for 10-15 days before your Macujo treatment, then your new growth won’t be tainted and you should be OK.

      Hope this helps.

I still don’t know the date of my test, just that I will be getting one eventually. I have fine light brown hair that’s fairly short. I was using frequently, but in very low doses compared to many users. I don’t think i have smoked a whole bowls worth in a day for at least 6 months.

    I just took a hair follicle drug test – here’s my experience:
    I got news about two weeks before the test that I had to take a hair test, and I freaked out because this is a job offer of a lifetime.
    I smoked about four times in the three months leading up, including twice in the most recent month (but more than 7 days, so it was definitely grown out by then).
    Obviously I’m not a consistent smoker but I for sure did not smoke after realizing I had the test.
    I did the Macujo method exactly as instructed about 6-7 times the week leading up (I didn’t have the nexus until then). The last time I left the vinegar and clean & clear in for about 45 mins instead of 30. The day of, I did the Zydot treatment within a couple of hours of going in.
    I didn’t shave my body hair in hopes that they just wouldn’t ask for it, or I could convince them to take it from my head. When I went in, the lady said she had to take it from my head because I had hair there. She cut from the crown of my head and made sure it was definitely down to the scalp.
    I prayed and prayed, and decided that regardless of the outcome I was done with weed for good. It is just not worth it. Drug tests, the monetary cost, the risk of getting in trouble with the law. My best advice is just stop smoking the damn stuff.
    It took 4 business days for them to get the test back to my employer, but I passed.
    I only used about 1/3 of the Nexus shampoo with roughly 20 washes. It’s insanely expensive, so if anyone wants to make a deal I can mail them the other portion of it. It’s the old kind and I’d say there’s at least 30-40 washes left, depending on how much hair you have. Reply to this comment if interested.

      How much do want for the shampoo? I have a prescription for hydrocodone and can take up to six a day. Just got a tremendous job offer and it is dependent on passing a hair test. I bought pills to do an internal detox and some shampoo. Not the expensive stuff ad am worried. What should I do.

      Please send me your shampoo! I have an unexpected hair test in less than 7 days! I’ve been sober for 13yrs. But, idiotically slipped for the last year and fault, using high amounts. Thankfully, I’ve gone Beck to my sobriety easily and will never let this happen again! If if fail, CPS will take my young cold or of my car and place him. I’m so scarred. Have no one
      No money. I’m all my child has, and don’t won’t him to suffer from my stupid mistake. Is be completely be very suicidal if they take him. Plz plz plz plz help me!!

        Hey Christian, Please let me know what happened in your situation. Was this a 2nd or 3rd test? I haven’t heard of CPS doing anything drastic when it’s a first time test. They usually ask that you attend N/A and rehab then they do a follow up on your situation. Sometimes they will place a child with relatives or someone you may give guardianship to while attending N/A and rehab.
        Hope all is well. I have been down that road too many times in the past, so I know where your desperation is, but best for you to do is be honest with your caseworker and don’t give up on your child or yourself. Also, just so you know, being proactive looks way better than waiting for the bomb to hit…meaning if you go your case worker and admit your issues AND have already registered for treatment and already have a person to care for your child while your in treatment – trust me they will be happy to hear that – judges too.

    I have been smoking concentrates heavily for years and have a hair test coming up that supposedly tests back a year. I have up to 6 months before I can take the test, how long in advance should I stop smoking if I don’t want to use any remedies. I understand I need to detox my body before hair can grow clean but I just want to be extra sure, I always thought 90 days wasn’t enough time.
    Thanks

      For heavy users, give yourself at least 100 days from the last use to clear your system. Then cut your hair down to 1.5″ for the 90-day sample.

    So, if he urine tests are not 100% accurate then how on earth can they be used against you?? I would urge everyone not to allow anyone to test you! Even if you don’t get the job because of your refusal to be tested, it is better than having anyone be able to truthfully say that you failed a test. JUST SAY NO TO DRUG TESTING!!!!!!!

    I’m currently panicking because I smoked maybe a quarter of a dime a couple weeks ago and my test is roughly in 45 days. the only time I smoked before that is before the 90 day mark. do you think that little amount of weed will show up in a hair test?

    hi jz, first, thanks so much for putting up this site, and freely offering all this information to everyone!
    I was a heavy smoker for several years, up until march 1st. I quit and havent smoked since. Now, I shave my head down to the scalp about once a month or so, and have done so since I quit, however i dont remember exactly when. I am expected to go for a interview on may 4th, and if all goes well, I will most likely b tested, hair, saliva and urine (from what others who have started there have told me, I dont know for sure, and that sounds a bit excessive, but Im going on that just in case) Now, I do not have the money to purchase that rid shampoo. I live on a very tight budget and its just not possible. If I shaved all my hair, head to toe, now. would that look to obvious, and if not, would it b enough? I have very thick body hair. what would you recommend?

      If you shave everything now (April 24), there won’t be enough hair to sample anywhere on your body until late July. Hopefully, they will drag their feet on the test.

    Jay, I haven’t smoked in three years, but ate an edible candy in December, and had a portion of a pot brownie about a month ago. I’m applying for a job I really want, which has the hair test. Since I’m not a consistent or habitual user, should I worry? I’ve been paranoid about even sending in my application for fear I would be denied a chance for reapplying if the test shows positive. Im a girl with long hair too so don’t really want to destroy it either, however it does get dyed once every month, does that help? Thanks for your advice in advance!

    Hi Jay- I know this might be a strang question, but here goes. I’m having a hair follicle test sometime this week (possibly tomorrow). I don’t smoke personally, but my adult daughter does, daily. She does not live with me, but comes to my house nearly every day. I know she uses my hair brush, hair bands, etc. Will this cause me to fail the test? I didn’t think about this possibility until late last night & soaked my brush in a variety of things (tea tree oil, listerine, rubbing alcohol, etc), but I had already been using my brush regularly. Will her use of my brush contaminate my hair? Thank you for your advice.

    I haven’t smoked for over 2 1/2 years. I shaved my head, when I knew my system was 100% clean. I’m involved in a CPS case that is about to close, but I had a moment of weakness and smoked a small amount about a month ago. I already have products that include the active ingredients for the Mancujo process, but feel the need to inquire about the Nexis product. My suave shampoo and aloe vera gel include propylene glycol, and only cost a few dollars each. I cannot spend the money for the Nexus product that is so adamantly suggested here. If I substitute the products that I already have, can I allow my paranoia to abate?

      The only evidence I have seen mentions the old formula of Nexus Aloe Rid. It’s possible that the reason Nexus works is the propylene glycol content, or it may be a mixture of chemicals.

      I’m not a chemist, so I don’t want to recommend a substitute unless there’s clear evidence it works. And I haven’t seen that, yet.

    Hello JayZ and thanks very much for all the great information on this site. I’ve come to this site several times over the last few months looking for information and it’s been very helpful to this ole guy who’s been smoking since 1974! I finally had to quit after losing a great job because of a drug test. When I first started there they used urine tests and I used different methods for passing the randoms but the best had always been synthetic urine. Then they switched to mouth swabs and I panicked..only to find out after some research that the swab is actually the easiest one to pass. Rinse with hydrogen peroxide, simple and effective as I’ve passed many of them since I learned this trick and I was a very heavy user smoking several times a day, even at work. The event that led me to losing my job are complicated but I was finally caught.

    My question: On June 15 of this year I quit all together once I learned that I would probably have to take a hair follicle test for my CDL licence. A couple weeks ago in a moment of weakness I took about a half a hit from a hitter. MAN WAS THAT GREAT!! But now I’m wondering if that little amount is enough to fail me on a hair follicle test?

      Well, when you show up you won’t have 6 months of hair available.

      But I wouldn’t worry too much. Your situation isn’t that unusual these days, with modern grooming habits and hair styles.

      My guess is they will go ahead and test you for 90 days, then retest later on if they want the full 6 mos.

      They might be saying, “6 months back”, just to scare-off regular users.

      You have already done what you need to do.

      If I were you – since you’ve already shaved your head – I’d try going into the test with only ~1 inch of hair. That will eliminate the oldest ~30 days of history from your hair, and it’s long enough that they may accept the sample.

      If they don’t accept that short of a sample, then they may ask you to return in 4 weeks, when your hair is long enough… which only helps you.

      Good luck on your test. No one should lose custody of their child… for using natural marijuana. That’s crazy!

      It doesn’t work that way, because drug traces enter your hair follicle from your bloodstream.

      Until your blood level drops below the minimum test threshold for the drug, all new hair will be tainted.

      So, shaving doesn’t help as long as your blood is tainted.

      For most people, it takes 15-45 days for drug traces to dissipate enough in your blood to begin growing clean hair – depending on the drug and how much you used.

      On top of that, it takes tainted hair about a week to grow all the way through your skin.

      Once clean hair starts growing through your skin, you need to let enough of it grow to be tested. For most people, that’s 1.5″ for a 90 day test – at least 90 days’ worth of growth.

      This is why I recommend abstaining for at least 100 days before a hair test for light MJ user, and 110-120 days for a heavy user.

      Hope this makes sense. Good luck!

      If you are within this margin of error, then consider the cleaning regimens discussed above.

    I stopped taking pain killers and quit smoking marijuana back in September 2016. I have a hair follicle drug test coming up possibly on April 29th (for my dream job). So by then it will be approx. 8 monthes that I quit, but the job I am applying for has their drug test going back one year. I’m also extremely worried since my bf still smokes marijuana around me. I can’t cut my hair super short either. So my question is, do you think I should be ok with the macujo method?

He is definitely a moderate user and doesn’t plan on using any more. We are going to buy the Nexxus & use the recommended method. Do you think he will be clean in time of his test?

      Cutting it close – you’ll need 100 days b/w time of last use and taking the test.

      Suggest you cut his hair down to <1" (all over head) right before the test to have the best shot at passing. That is only ~60 days of clean growth vs. the 90 days the lab will want - but all of the hair should be clean, and they might accept it. If you want to be extra careful, shave his body hair off, too.

      All the best!

      You are a walking case study for a person who needs a Macujo or Jerry G cleaning. So, yeah, that’s what I’d do.

      No, you have it wrong: the test lab cuts the hair sample from the *scalp line out*, so they always capture the most recent 90 days. Cutting the ends off only helps to protect you from test lab techs who don’t do things correctly (which happens).

    I’m terrified and need help. I was an occasional smoker smoking maybe 2 times a week but have quit using about a month ago. I recently shaved my head down to 3/4 of an inch (not because of the drug test just my preferred haircut). My drug test is in roughly 60 days will my hair be long enough for the test and would it come back positive if I don’t smoke anymore?

      Do this, and relax:

      Before your test in 60 days, just make sure you keep cut down to the same length – 3/4″.

      That’ll leave about 45 days of clean hair on your head – not enough for a full 90-day sample, but they may accept it anyway.

      Also, shave your body hair off – or at least down to a stubble – so they can’t sample that.

      Best of luck!

    I have been. Habitual smoker for 15 yrs. I’ve chilled out on my consumption but last smoked April 20th of 2017. I’m trying to take my ex husband to court for custody and my judge will strip all rights if I fail a hair follicle test. Which would be the best method and likely hood of passing a hair follicle and when would be the earliest I would be able to try?

      If you can abstain and delay taking the test for another 120 days / 4 months, then do it. At that point, the latest 1.5″ of hair will be clean of THC metabolites.

      If you cannot delay it that long, then your next best bet is one of these two cleaning regimens (Macujo or Jerry G): https://hairfollicledrugtest.info/thc-detox-clean-hair-home-remedies/

          You should be clean enough to pass a 90-day hair test… assuming the test lab/technician cuts the sample properly (from the scalp line, out).

          The reason you want to consider cutting your hair down to 1.5″ all around is to avoid getting into trouble if the lab tech doesn’t do his/her job, per the spec.

    I took one hit from a pipe within the past 90 days. My use is so rare that I can’t even recall when that was, but at least a month or more ago. I have to take a test and don’t know if they’ll be taking a hair sample or not. If they do it will be body hair for sure. My partner smokes almost daily (one or two tokes) so I am exposed to light second-hand smoke regularly.

    I’m frightened because I was just diagnosed with cancer and the prospect of loosing my job – and my health insurance – is overwhelming. What are my chances with only that single bump in my system within the past 60 days or so?

    Hi Jay,

    I recently was offered a great job making more money than ever before. However, I was a habitual daily smoker for many years – multiple times a day. It turns out, this job required a hair drug test. Not willing to lose out, I immediately quit smoking (obviously) and didn’t get that job, luckily, but they still wanted me for a different position, it would just take a few extra weeks. GREAT! So, in the interim I was like a sponge doing research all over and kept coming back to this page. I was totally willing to go bald – even as a female!

    The first thing I purchased was the Nexxus Aloe Rid with the Zydot Ultra Clean. Then, I made sure I completely understood the Macujo method and purchased all of the necessary supplies. I waited a few weeks to start the process, when I knew I had about 5 days to go before the test and so it began….

    The steps I took started initially with a color bleach with permanent color. Then I did a T/Sal wash then the rest of the processes was as follows:

    1. spray hair damp with warm water
    2. saturate with white vinegar
    3. soak 15-20 min
    4. add clean & clear deep cleaning astringent – did NOT rinse vinegar out
    5. soak 30 min
    6. rinse with warm water
    7. wash with nexxus aloe rid – (washed, let sit / washed, let sit for 10 min – rinse well)
    8. wash with cap full of Tide – (washed, let sit / washed, let sit for 10 min – rinse well)
    9. wash with T/Sal – (washed and let sit for 5 min – rinse well)
    10. wash with aloe rid- (washed and let sit for 5 min – rinse well)

    On day one I did this process one time following an initial T/Sal wash and color bleach with permanent color (coloring 2 days prior to starting the process.)

    On day two I did this process twice. I also did another color bleach with permanent color between the two processes.

    On day three I let my skin rest because I the skin around my hair line and behind my ears was chemically burned and peeling. The vinegar was awful feeling at this point.

    On day four I did this process twice.

    On day five (test day) I washed with T/Sal then Nexxus Aloe Rid (finished the bottle off) and then did the Zydot Ultra Clean. I was concerned with the Zydot because there was not enough of step two to cover all of my hair, but I forged ahead anyway.

    I had really long hair, went back and forth about cutting it to shoulder length but decided not to give them more rope than needed to hang me with so I cut it off on day three. I was also concerned about running out of the Nexxus Aloe Rid too soon.

    To my amazement – I PASSED! Though they did not cut my hair to the scalp, they came out about 1/8 of an inch from my scalp skin.

    It should be noted I had also been up for another job requiring a urine test. At this point I was 5 weeks clean and ended up needing synthetic urine because I was still testing positive. (I had bought a 15 pack of test strips.) I tried two kinds of detox, neither worked, hence the synthetic. But this was a back up job in case the hair test didn’t make it. I did pass with the synthetic but didn’t need the job.

    So, my question now since there are random tests and I can get called at any time to take another – is my hair still ‘clean’ given that I’ve not smoked anything since 5 weeks prior to doing the process or do I need to keep some Zydot Ultra Clean on hand, just in case? I don’t know if the random tests are hair or urine, but even after 6 weeks my urine is still testing positive! I’d hope that should be rectified in the next week or two – good grief! But, if not, I’ll keep some synthetic on hand. I’m mainly worried about needing to do the entire hair process again, which cannot be done on a moment’s notice and I cannot afford to keep the Aloe Rid on hand for the next several months.

    Thanks for the information and putting this page up, it was a life saver for me!!!! If you can advise about the hair going forward, I’d appreciate it 🙂

      You will probably just squeak by. When you get tested, it will have been 110-120 days since your last use. The make extra sure, cut your hair down to 1.5″ all around (or less).

    I have a test on Monday 7/10. I was an every day user for the past five years. I haven’t smoked since 6/5/17. The day I got a call for an interview I ordered all the products from test clear. I have done over 10 macujo treatments in the course of two weeks. After my fifth treatment I made an appointment with my barber who’s a good friend of mine. The day off the hair cut I used the ultra clean soap and asked him to cut a bunch of hairs to submit to hairconfirm for a test.
    Two days later the test came back negative
    My hair is about 1 inch long now.
    I shaved my entires body down to my feet because the company who is going to test me is psychemedics and I heard they don’t mess around.
    What are the odds of me failing? Should I go ahead and bleach on top of do you think I’ll be good? I haven’t been around any smoke in over a month. Please advise. I’m very stress out like most people on this page.

      If the lab technician does his/her job correctly, then you don’t need to be worried, because:

      – it’s been more than 110 days since your husband last used, so 1.5″ of clean hair has likely grown through his scalp by now
      – the lab tech is supposed to cut the 1.5″ (90-day) hair sample *from the surface of the scalp, outward*.

      For you, the risk is in how well the lab tech does his job. If he cuts the wrong section of hair (not close enough to the scalp), then he can pick up some growth older than 100 days.

      I did not find much evidence that the Macujo / Gerry G methods work reliably for meth, but I do know lots of people use the same (or similar) cleaning regimens for that drug.

      No, I do not know of a good reason you can give a test lab for refusing the test.

      If the test is for employment, then your employer has a legal right to fire/not hire you based on your refusal to take the test. Courts also have rights to take action based upon your refusal.

      Sorry I could not provide more uplifting advice 🙁

      Best of luck on your test!

      Cleaning regimens and shampoos can only clean the hair exposed on your head. Once cleaned, that hair doesn’t need to be cleaned/stripped again.

      That said, your hair is constantly growing. New/fresh tainted hair will continue to grow, after you wash it.

      This is why you should strip/clean your hair up to & including the day of your test, just to be sure.

    I’m a guy with long ass hair. I smoke all day everyday.

    If I wanted to pass a hair follicle test some time in the next month or two (if I stop smoking today), can I use the Macujo method WITHOUT cutting my hair? Or is cutting my hair short an essential part of the process?

    The Macujo method worked perfectly for my roommate, but he has short hair. I really don’t wanna cut my hair off but also don’t have a thousand dollars for a done of Aloe Rid… But I’m hoping I can just focus the cleaning to the top of my head?

      The Macujo method is for people who don’t have the time to grow fresh clean hair from their own head… and for people do not want to cut their hair.

      If you have to economize, then thoroughly treat/clean from the roots outward at least a couple of inches. But not as good as treating whole head.

      Good luck!

    Hi Jay!!
    So I stopped smoking July 15 2017, before that I was a chronic smoker, a few bowls everyday for the past 4 years. I graduate from college next tuesday and am starting to job search. I don’t suspect I will have a job until sometime in september, hopefully I won’t get a job until october to give me enough time to detox and all that fun stuff. But I am now getting paranoid that I might have to do a hair follicle test for whatever job I get offered. So I am being proactive and trying to detox now so I am prepared for whatever test they throw my way. So what steps can I take now and going forward to get all the THC-COOH out of my hair? I definitely don’t want to do the Marcujo or Jerry G method as I don’t want to destroy my hair. I work out for 30 minutes everyday, I sweat a lot and I drink about a gallon of water everyday. Everyday I take 2 fish oil supplements, 2 400IU vitamin E oil supplements, 1 500mg niacin vitamin, and 2 hair skin and nails supplement with keratin and biotin. Next week I plan on visiting the steam room daily. Also, I have very thin hair, down to my shoulders. Now just to reiterate how paranoid I am, I don’t have a job yet, I have no clue when I get a job if I am going to get a urine or hair follicle drug test, I am just trying to take preventative measures to insure I am prepared for anything. Oh one more thing, My shampoo is Nioxin number 3 which contains propylene glycol and salicylcic acid in it. I have been using that everyday making sure to really scrub it in my scalp and I leave it on there for about 2 minutes. Also should I start putting baking soda in my hair and then use my shampoo? One last thought, would you recommend me purchasing propylene glycol off amazon and add that into my daily shower regime? Does all this sound like it will help me if I end up getting a hair test in the near future? What else can I do besides the Marcujo and Jerry g method?
    Thanks in advance for all your help!! I am sure you have saved many people from this dreaded hair follicle test. You are the best!

      Unfortunately, there is really not much you can do to speed the process of THC metabolites declining in your bloodstream.

      All of the dieting, supplements, foods, and healthy living don’t move the needle, that much. Time is the only cure.

      Regarding alternatives to Macujo: sorry, but I don’t know of any other methods with strong proof. I def. wouldn’t use prop glycol separately. Not the same thing.

      Don’t know much about Nioxin 3, it hasn’t really come across my research feeds. I’ll look into it, though.

      Good question. Always use Macujo right before your test, to strip your hair down to the roots.

      If you clean too early and then wait days/weeks for the test, new (tainted) hair will grow through your scalp, leading to a negative result.

    so i was a heavy smoker for like 3-4 years every day almost, then took off for about a month and a half back in may. 4th of July I started smoking two or three times on the weekends, every weekend to date. Last time I lit up was this past Sunday.. So i haven’t been smoking everyday a good amount and very recently. I have a hair test coming up either this coming friday or sometime next week (not 100% sure yet but definitely soon). I bought three bottles of “Stealth Detox” shampoo, and i’ve been running and sweating a sh*t ton to try to get it out of my system. I guess my question is would I be good JUST using the shampoo, or should i definitely do the MACUJO method? ALSO if i do have to do the MACUJO method, would I have to get the expensive shampoo you mentioned or could i just use the “Stealth Detox” shampoo as a substitute..?

    Hey JayZ,

    I applied for a job at a healthcare company and just recently found out that I was being hair tested from a friend of mine that currently works for them. I am in the final stages of the interview process and it is likely I will get the job offer but will have to pass the test. I read the reviews on the Macujo process and this is something I am willing to invest in. However, I do have some questions. I will most likely find out early next week if I will get the offer (which I am confident I will). I do not know how many days in between there will be from when I find out I get the job from when they want me to get drug tested. How many days prior to the test should I conduct the Macujo process? And is there a certain amount of times I should do it in a day? This is a dream job of mine and I have been smoking pot (a joint a day) daily for about 5 months, if not at least 4/5 days a week. I also did some cocaine about two weeks ago. Prior to that the last time I did coke was in the beginning of August. If there is anything you recommend please let me know. Thanks!

The day of my test I again used the aloe rid shampoo first then the ultra clean how it was instructed to use about an hr/hr and a half before my test. How do u feel my chances are on passing that test? Prior cocaine use before that was over 6 months ago. Will one line be enough to fail using the precautions I described above, just happy I didn’t end up getting more that night, I’d be sweating this one way worse then I am right now.

    Hey man. I did a combo of both. I did a shampoo and vinegar wash, bleached my hair, and dyed it back it’s original color.

    I have short hair. I went and got a test taken myself.

    The lady DIDN’T shave from the root she did what she could with scissors.

    She took pretty much the tip of my hair on my head.

    What do you think about my chances?
    I will know in 3 days and update bit I just want to know what you think.

    I smoked about 5 days ago and I was a really heavy user before. The test came out of nowhere so I did what I could.

    I did the dye trick and got tested myself because IF it doesn’t work I can try it one more time.

    But I got tested less than an hour after I cleaned my hair.

    What do you think?

    Hi Jay,

    I smoked three or four days in a row about 5 weeks ago but only about 2 or 3 hits each time. and have been very infrequent user before then. I have a hair test coming up in about a week. Should I do the Macujo method just to be safe?

    I have smoked for about a year with some week long breaks. In the past few weeks i cut back a lot and only 3 days a wek and I haven’t smoked in 5 days. If I used the Macujo/Growman with Nexxus can I pass my test in 3-4 weeks from now? I plan on shaving all my body hair and I am gonna have head hair roughly 1/4-1/2” long on my head. I am also for the next 3 week gonna was a few time a week with Neutrogina T-Sal. What do you think?

      For a heavy THC user, you’ll need at least 110 days of abstinence from last use; and, you’ll need to cut your hair down to 1.5″ all around right before your test.

      This is the only way to guarantee that you will pass.

    Hello, I have one quick question about a hair follicle drug test. So I stopped smoking marijuana on August 7, 2016 and today’s date is December 17, 2017. I recently taken my hair follicle drug test on December 8, 2017. I rarely smoked marijuana; about 0 to 1 times a week if lucky. If I wasn’t lucky, then I never smoked at all, because I never kept marijuana in my possession. Psychemedics Corporation will test my hair follicles for marijuana. All of my friends and family say I should be okay, and the job I applied for say they go back 6 to 8 months. I’m a little paranoid about the hair follicle drug test, because I know I’m not innocent inside. Will my hair follicle drug test be negative or positive? What do you think?

      Sorry to tell you this… although smoking once a week isn’t exactly “heavy use” by most peoples’ standard, it is enough to cause you to fail a hair drug test, if you’ve been doing this for many months. I really hope I’m wrong, though.

    Hi Jay Z, (12/24/2017) Marry Christmas & happy holidays.
    I’m expecting a hair or urine drug test in family court in about 5 to 10 weeks from now.
    I use to smoke really heavy like all day everyday and I did quit smoking the first week of July 2017 as all this family court custody battle stuff I’m now going thruogh started.
    I did stop the first week of July for about 3 & halve to 4 month’s.
    About month 4 mid September I started smoking again but only for about 3 weeks before I stopped again in the first week of December 2017 due to the heavily influencing advice from my family court lawyer.
    I was only smoking like 2-4 times a day this time not all day like before.
    I am now expecting my ex (my sons mom) to request the court to have me submit a drug test with eathr hair or urine don’t know witch just expecting her to the request. Didn’t know when the date is yet but will most likely be someware around 6 to 10 weeks from now when we go back to court, waiting for the family courts to set the Magistrate Hearing Date most likely somewhere about mid/late January to mid February of 2018 about 5 to 10 weeks out.
    Becuase I work outside in the hellish heat of south Florida I tend to normally keep my hair pretty short about 1 to 2/10th of an inch almost shaved but not quit and on a normal basis. I naturally cut my hair with the shortest gard on my hair clippers on a regular basses.
    This time when I stopped smoking I did shave my “entire body” not my head just my body, about 8 or 9 days after I stop smoking. Keeping the hair on my head realy short as I normally do provable by every picture I’m in.
    What else do you think I can do to help clean my hair and urine out best as possible as I’m waiting and expeting one or both of these test someware in the next 6 to 10 weeks.
    I’m already looking in to doing the Jerry-G method as well.
    Because I keep my hair so short I think it will be pretty easy to bleach and dye, however they probably not going to be able to get a test sample from a head anyways because my hear is keept so short. I shaved all the hair off my body as soon as I knew we were going back to court just to be on the safer side of things.
    My family has very thin, light and short body hair to begin with so hoppfully in the next 5 to 10 weeks in court it won’t be obvious that I shaved in preparation for a hair follicle drug test.
    Do you have any thoughts or suggestions to help me with this sticky situation I’m in.

      I think you’re doing everything you can.

      You ARE at risk if your hair is 1/5″ or longer at test time – but only barely.

      If you can cut it down to 1″ all around + do Jerry G, you’ll stand a good chance of passing. Don’t forget to get rid of body hair in case they opt for that due to short head hair.

    Thank you so much for putting this site together. I’ve been smoking several hits a day for the past 3 months after not smoking for 6 months prior. I know I’m in the ‘danger zone’ and plan to use the Macujo method if I land this job. Since I am a lady with long hair (that is my point of pride), what do you recommend as far as conditioners go? Does it hinder the efficacy of the method if I’m also using my conditioner to maintain the healthy of my hair?

      You are definitely at risk. That’s enough use to build the metabolites up in your bloodstream. And Feb-March is too close for comfort. I’d do a cleaning regimen (Jerry G or Macujo) – or try to get the test pushed back to mid-/late-April if you can.

    I’m not an avid user, I’m not even an occasional one. I smoked weed once on Dec. 1 (took about 3 hits off a friend’s bowl) and on Dec. 15 I had one hit of a friend’s vape pen. That was the only time I’ve smoked from June 2017 to date.

    I have a 5 panel hair test soon (Feb. 17, but I can get an extension). What do you think? I don’t want to pay for the Aloe shampoo, etc. unless necessary and I wanted to get your opinion. Can that small of an amount show up?

    I have applied for my dream job and think I will get it. I took a couple of hits about 2 months ago and hit 1 line of cocaine about 2 weeks ago. I keep my hair cut about 1/8 of an inch long at all times. Is there a minimum limit to what length hair they will take for the test and will the Macujo method work for really short hair? I will probably be hired in 2 weeks and not sure when test will be.

      A standard 90-day hair drug test requires a minimum of 1.5 inches (3 cm) of hair to sample.

      That said, some techs will accept a shorter sample – it depends on the lab order and the lab that is doing the testing.

      Macujo works on hair of any length, but I’d say your real risk is that they will take a sample from your body hair or arm hair instead of your head. You might want to shave it all off, to be safe.

I quit yesterday and not going to smoke anymore because I’m graduating from college and stepping in to the professional world. The question is when do i do this? From my understanding the thc is in the blood going to the hair so if i do this this week or something will the thc be gone from my system forever or is it just getting covered up for the test and. will the hair crow back with more thc in it? I will have a drug test like this but i don’t know how soon. So im thinking about buying a detox for my whole system something like NHQ 7 day cleanse or something. And then after like a week or 2 to use the mocujo method… What do you suggest for my situation? I want to get rid of weed completely out of my system forever cause im not going to smoke anymore.

    Jay Z,

    I am not sure on the exact date yet, but I most likely have a pre-employment hair test coming up in Mid April 2018. I have been smoking since 19 and I am 27 now. Over the past year I have smoked 1-3 times a week (about 15 hits a week at most). I exercise regularly. I have been sober since December 6th, 2018 and it has been 116 days sober to date.

    I am nervous because I have heard the company test up to 6 months of use, but I am not sure if this is true or not. It is not a government or law enforcement job so I am wondering if they are just trying to scare me. Since my sober date of 12/6/18 I have gotten 3 buzz cuts and 1 hair cut fairly short (buzz on sides, short scissor cut on top).

    If I do get through the interview process and have to take a hair test in mid April 2018 what do you think my chances are of passing? I am not sure if it is necessary to do the macujo or jerry g method, but I would like your opinion. A very good friend referred me for this job and I really want it as my current job is horrible. I don’t want to make my friend look bad by failing the test.

    Should I shave all my body hair and make sure my head hair is 1.5 inches? Or is that too suspicious? Any help would be greatly appreciated. Thank you.

      If you don’t give them more than 1.5″ of hair to sample, then they can’t test more than 90 days back.

    I have long hair and don’t want to cut it. Smoked for a year three times a day on average. Quit 60 days ago. Going to use majuko with aloe rid and clean and clear. They say I have the job, going through hiring process and don’t know when the hair follicle will be. So my question is should I use the majuko method a few times now using the aloe rid sparingly and then again when I find out when the hair follicle will be. Or do I wait till they give me the date or does it matter. My concern is since I don’t know the date of the test that when notified I won’t have adequate amount of time to complete the process properly

    My son is a very infrequent smoker and hadn’t smoked in several months. In mid March he had 2 hits every weekend night for 3 weekends. He found out he may have a hair follicle test for his job. He went to a private facility to see if he would pass/fail before doing the one for his job. It came back negative. We’re wondering how this is possible. Error/fluke? Or because of his infrequent use? Or do these private places not screen for such small amounts that an employer might? It was processed through a reputable lab and the results read Marijuana Metabolites Negative initial test level 1 pg/mg MS Confirm test level .1 pg/mg
    I told him he should be tested again to make sure but he doesn’t think that is useful. Should he cut his hair and/or try the listed methods? He should have a couple more weeks until he has to test. We’re just really confused and stressed. Thanks!

      Your son most likely tested negative because of the low use. 2 hits x 6 nights = 12 hits total. Not a lot.

In the last 15 weeks I have smoked weed kind of heavily for 1 week, and then for 1 day a week after (approx 10 weeks prior to scheduled test test) and have taken maybe… 6 x pills within the last 2 months prior to test. Whats your suggestion on getting this out of my hair to pass the test? Im considering cutting a good 4-6 inches off my hair and trying the Jerry G. I do not want to bleach my hair tho.

      I wouldn’t waste your time dying in addition to Macujo – that regimen is already pretty hard on your hair and scalp.

      No way to know what your exact chances are w/ Macujo, but they are definitely better if you do it.

      Here’s a recent hard case that passed using Macujo: https://hairfollicledrugtest.info/#comment-10259

      Given that you only did it once, you will probably pass. The hair test is designed to detect longer-term heavier use than that.

      Best of luck 😉

      Yes, the Macujo cleaning method works for any kind of hair. The JerryG method is harsh on your hair, so I tend to advise people with long thin hair to avoid it if they can. That said, it also has a good history of working.

    I never really liked weed until I started working full time and my body started hurting like hell. Starting in January of 2018, I probably smoked 3-5 hits a night after work. I also ate a few candies throughout the last 6 months. I want to get a trucking job but they want to do a 120 day hair follicle test. I quit smoking weed on July 23. It has only been 2 weeks. Do you think that small amount will show up since it was fairly consistent use? The test isn’t immediate, I was honest and told the recruiter that I had eaten an edible lollipop. He said I can wait out the 120 days before the test. I’m just impatient and wondering if I should wait just to be safe or if you think I’ll be good? If I fail the test I’ll never be able to get my trucking license. Thanks for the info, this site has some well-researched stuff.

      You should definitely wait 120 days before taking your test.

      I’d recommend waiting at least 150 days if you can, given your description. You probably won’t be growing 100% clean hair through your scalp for at least another 4 weeks…

    Hello,
    I need some advice/guidance please! I have been a daily heavy user of cannabis for last 20 years. For the last 5 years no less than an ounce of Chronic every 3-4 weeks. I am 6’2 inches tall and 275lbs(overweight). I was offered a Great job in July, but they require a hair test. I haven’t used cannabis since July 24th, which gives me 60 days clean as of now. I shaved my head and body at 30 days to try to force a urine test. This worked, but they are giving me 60 days to grow my hair out for a hair follicle test(started job 1st week of Sept). I had to use dilution to pass for the urinalysis. I am still failing at home urine tests now at 60 days clean without dilution. At the time of my hair test I will be at 100+ days clean of cannabis, and my hair should be right at an inch or 1 1/2 inches, because I will be sure to trim my hair again. Should I be in the clear for the follicle test they need on file? Right now I am a temp employee until the hair follicle test is complete. This is a great high paying career opportunity that I don’t want to mess up!

      If you are still failing a urine test, then your blood concentration is still high enough to fail a hair test. That’s because your hair follicles get much of the drug traces from your blood.

      The rule of thumb is that you need ~100 days of abstinence **from the date of your first clean urine test** to grow enough clean hair prior to a standard hair test (90-day look-back).

      Clearly, you won’t have enough clean hair on your head for a test 60 days from now… at best, you’ll have 1″ of clean hair assuming your urine tests clean **tomorrow morning**.

      Time to look at stripping your hair w/ Macujo or Jerry G.

    Not sure if you still check this but ya worth a try. I need some advice. So sorry for the long text just trying to be proactive

    I’m a female, 5’ exactly, heavy pot smoker (smoked almost everyday for like 2 year – sometimes I would go cold turkey for a few weeks and get back to it)

    I have a job opportunity and it will test me around mid May. We are now toward the end of January and I haven’t smoked since mid January. If tested a month prior to starting (May) I will be without smoking for a little over 120 days. I was wondering if you think my new hair should be clean by then?

    I do not want to cut my hair short short, I have long hair, but was told they would only test 90 days back. Do you think the 1.5” of new hair will be clean without any treatment? Or would treatment be advised? I don’t mind chemistry treatments as I am always dying my hair. I will be going blond next month anyways and for that they will be bleaching a good part of my hair

    If treatment is recomended how soon before the test should I start?

      Hey, you are right on the edge – 120 days SHOULD be long enough to test clean… except there’s some variability in this number based on how fast your hair grows

      darker/thicker = grows slower = higher risk of failing at 1.5″
      light/thin hair = grows faster = less risk of failing at 1.5″

      There is also the risk of human error by the lab tech taking your sample. If s/he doesn’t cut it right, then they can end up testing older hair.

      I recommend cutting your hair down to 1.25″ or less all around or deferring for a month to be safe.

      The only other choice would be to use a cleaning regimen like Macujo (less hard on your hair / no dying) or JerryG (uses bleach). These are explained on this page.

      Regarding when to start treating hair, I recommend treating at least 5 days before the test and do it several times – including on the day right before your test (important).

    Hello I need some advice, today is March 15,2019. On December 31,2018 I quit smoking in preparation for a hair sample drug test. Yesterday March 14,2019 I got hired by a different job which required me to take a uranlysis test which I obviously easily passed, I took this job because I didn’t think the first job I applied for would call me back, my friend who works at this job told me the manager said they are going to start interviewing next week. Hair sample drug tests are usualling 2 weeks after the interview. So I’d say the beginning of Apri is the hair sample drug test. So my question is will I pass a hair sample drug test if I quit smoking December 31,2018, smoked once March 14,2019 (4-5 hits) and my drug test is April 1,2019

      I am assuming you were a regular user prior to Dec 31, 2018? if so, then you are definitely at risk of failing if your hair is 1.5″ or longer on April 1.

      If you cut your hair down to 1″ all around (55-65 days of growth) or less, then you will stand a much better chance of passing.

      The lab tech may not like the shorter hair sample, however – if so, then s/he may opt for a body hair/arm/leg hair sample instead. So shave those bits, too, if you really want to be safe.

      Good luck!

In like mid jun 2019 i took a xan bcuz i was dying in pain. In jul 2019 i took two hits of a weed vape bcuz i left my cbd at home and i was with my bf that night.

      Don’t worry too much. At least, not about the weed – you didn’t consume enough to register on a hair test.

      wrt the Xanax, you didn’t say exactly how much you’ve used… so I can’t really weigh-in on that part.

    i was a heavy marijuana/weed smoker for about a year straight. smoked it and did dabs daily. i see in some comments i should be at least 110-140 days clean(for the hair test). im 60 days clean heading for the 90 day mark. only because i shave my head 1/8 inch every mouth or so. on day 90 or so i plan on cutting my hair again. then letting it grow to an 1″-1 1/2. for the test. the two answers im looking for is.
    1. Will wearing my same hat affect the hair drug test?
    2. Will the 90 day mark be good enough because i shave my head?

      1. hats don’t matter… the lab tests for a metabolite that is produced by your body when it breaks down THC – not THC directly. This is why second hand smoke / handling MJ cannot fail you.

      2. given your heavy prior use, you need 110+ days of abstinence before to walk into a hair test with 1.5″ of clean hair. When & how frequently you shave your head makes zero difference in this fact.

    Second, will the Macujo treatment work on body hair (arm pits and chest)? As I don’t have hair on my head, nor enough time to grow it out, I know they’ll take it from my body. I’ve been clean for about 70 days but was a heavy smoker prior (3-4 times a day of the good shit). If not, is there a body hair cleans you know of? Any recommendations would be greatly appreciated. Thanks

      Excellent question. Yeah, it should work the same way – but it’s harsh on your hair and skin and I don’t think you’ll enjoy how it feels under your arms… just sayin. I’d probably shave that part, instead.

      You’ll probably pass if all you did was one bowl in 6 mos. I wouldn’t worry about stripping your hair w/ Macujo or another regimen.

In the last week I have came home and smoked a blunt daily for last 2-3 days. How much thc usage is needed to show in a folicle. I’m looking at doing the Apple vinegar rinse as my legs are the place they may pull from. I cutnmy hair regularly (clean trimmed not bald/ short wave length. Do you think a rinse is needed or usage isnt high enough to fail. What is the testing levels when dealing with hair.

      You sounds like a moderate long-term smoker.

      Sorry to tell you this, but you’ll probably fail a hair drug test if you take one within the next 100-110 days.

      Your best bet is to try one of the two cleaning regimens described above (on this page) – but follow the instructions exactly. Don’t guess at a different recipe or substitute / drop any of the recommended products.

    Great website man. Very interesting and detailed. Can you do one of the hair cleansing methods ahead of time, say a week before you do it every day and then let your scalp heal again for a few days if the test isn’t until two weeks ahead?

      No, you should do the cleaning regimen right up until the day of the test. For Macujo, clean your hair once a day for a week before the test. For Jerry G, it really depends on how much bleaching your hair can take.
