How can you beat a hair follicle drug test?
What it is, how it works, what does it find?
First off, the hair follicle drug test is a bit of a misnomer. The hair follicle is not what’s being tested.
Hair consists of the hair follicle, the part underneath the skin which is living; then the hair shaft, which is above the skin and is non-living. The hair shaft is what will be tested.
As you can see, the hair follicle is down in there under the skin. They are not going to test the hair follicle, which is just as well as it may reveal more recent drug use. Hair testing can’t reveal drug use within about the last 7 days before the test, because there’s not enough time for the drugs to get into the hair shaft above the scalp. What they are going to test is the hair above the scalp. Specifically, the first 1.5 inches of hair next to the scalp. This will reveal drug use within the last 3 months.
Hair follicle drug test detection times
As shown in the chart, for hair tests drugs are detectable after 5 to 7 days, then up to 90 days. The test will measure drugs in the first 1.5 inches of hair closest to the scalp. Hair grows 1.5 inches in 90 days, so that is the window of detection. They could go back longer by testing hair further away from the scalp but this is prohibited by protocol and sometimes by law.
That’s about 1.5 inches in the picture above. The technician is going to take about that much hair from right next to the scalp, not the ends of the hair. They are prohibited from using hair further away from the scalp which could reveal drug use for excessively long periods of time.
How a Hair Drug Test Works
- Once you use a drug of abuse, it’s processed by organs in the body and enters the bloodstream.
- The drugs reach the hair follicle. Some of it is processed, and some are unmetabolized.
- As the hair grows, the drugs are pushed out of the scalp into the hair shaft. The hair grows 1.5 inches per 90 days.
- The technician takes a 1.5-inch section of hair from the scalp and tests it for drugs of abuse.
Pros and Cons: Hair Drug Test Versus Other Types
Passing a Hair Drug Screen
The most reputable ways to pass a hair drug test are the Macujo Method and the Jerry G Method which we will explain further down. Unlike the Macujo Method, the Jerry G Method may take as long as 10 days. If you don’t have that much time, you want to look first at the Macujo method. Marijuana may stay in your hair follicles if you’ve smoked recently, but they aren’t testing the follicle, but the hair shaft cortex above the scalp.
The Macujo Method
We are not prescribing this method, we are describing one of the most popular methods to pass a hair drug test found online in drug communities. This method has only anecdotal evidence as to its effectiveness. However, it’s relatively quick so those who need to pass a hair drug test in 24 hours (1 day) sometimes look to this method. In any case, putting detergent and acne wash in your hair will harm the hair which is the goal, as that causes drug metabolites to leech out, but can also harm the skin so use at your own risk.
Step 1. First off, soon as you know you have a test, stop using drugs. Now, we’ve told you already hair tests cannot detect drugs used in the last week before the test but there is an exception. Sometimes, if you keep smoking, you sweat, and the drugs in your sweat gets on the hair and you’re busted. So, first things first, stop using drugs. You may even need to stop any tobacco use, as some employers test for it to keep down healthcare costs. Some employers may test for alcohol. Alcohol leaves the blood quickly, but metabolites are detectable in the hair.
Step 2. Rinse your hair with warm water.
Step 3. Put vinegar in your hair. Make sure you get down to the roots. That is the part they are going to test.
Step 4. With the vinegar still in, work the Clean and Clear down to the roots. Put on your shower cap, and leave the mixture in a half-hour, then rinse it out.
Step 5. Now shampoo with original formula Aloe Toxin Rid, you have to get it from testclear.com
Step 6. Now put on your goggles, make sure you have your gloves on and shampoo your hair with a dash of Tide detergent.
Step 7. Shampoo with Zydot, and rinse with warm water. Some people will do this several times. Remember, the more damage is done to the hair, the more drug metabolites will leech out, so the user may trade damage to the hair and scalp for a chance at passing the drug test. Lastly, if your hair is way too fried, they may go for body hair instead, so be sensible.
Now, if you have more time to devote to passing the drug test, about ten days, then you can try this scientifically-backed method called the Jerry G method, which relies on bleaching and dyeing the hair.
The Jerry G Method
Jerry G is apparently a real person, a smoker in an online smoking community (cannabis). He developed this means of beating a hair drug test. And, the method has been scientifically tested.
A study in 1997 verified that bleaching and dyeing the hair greatly reduced the detection of drug metabolites. According to the study”
The majority of the mean differences were in the range of 40%-60% (cocaine, benzoylecgonine, codeine, 6-acetyl morphine, and THC-COOH). For morphine, the mean difference was higher than 60%, and two cases (THC and nicotine) differed by approx. 30% (Jurado, Kintz, and Menendez).
The hair was bleached and dyed only once for the study, and they have a range of 40 to 60 % reduction in detectable drug residues compared to untreated hair from the same donors. In every case, they studied, the drug content of the hair was reduced by bleaching and dyeing. Using the Jerry G method, users bleach and dye the hair several times, greatly reducing detectable drug residues. Also, bleaching and dyeing are frequently used cosmetic procedures the safety of which is known, unlike putting Tide detergent in your hair, the safety of which is unknown.
|Here’s what you’ll need|
- You’ll need about 10 days. Step one is to stop using drugs.
- Use a permanent hair dye which is the same as your natural hair color. If your hair looks bleached, they may opt for body hair so make it look natural. Use your bleach and dye 10 days out from the test.
- Wash your hair with your Old Style Toxin Rid.
- Wait ten days, do the bleach and dye again. Wash with Toxin Rid old style from testclear.com
- On test day, mix your baking soda with a little water to make a paste, then put it in your hair. Leave it in for 15 minutes. Rinse it out with water. This will neutralize any remaining acids in the hair.
- Wash with Toxin Rid once again.
- Now wash with your other hair follicle drug testing shampoo, Zydot Ultra Clean.
This method has science on its side. Two rounds of bleaching and dyeing may be strong enough to make drug metabolites undetectable.

Do’s and Don’ts
Q: What is the best way to beat a hair drug test?
A: Our research indicated that bleaching and dyeing hair is the most effective way to decrease the amounts of drug residues in the hair. This is scientifically proven in several studies.
Even alcohol residues are decreased in treated hair (Kerekes and Yegles). According to the study:
“…an important decrease of EtG (alcohol metabolite) in hair could be found after bleaching and permanent wave treatment.”
Even if the technician looks for alcohol, residues will be reduced by bleaching and dyeing.
A further study is done in 2000, printed in the Forensic Science International Journal found all drug levels in hair reduced, including a decrease in the stability and detectability of benzodiazepines and opioids in the hair after bleaching and dyeing (Yegles, Marson, and Wennig):
“benzoylecgonine (decrease of 24.6 and 36.4%, respectively), concentrations for codeine, 6-monoacetylmorphine and morphine decreased more significantly (decrease of 57.5, 88.6 and 67.4%, respectively) as well as those of diazepam (benzodiazepine), nordazepam and 7-aminoflunitrazepam (decrease of 39.7, 67.7 and 61.8%, respectively). The results in this study agree with those of other authors that bleaching affects the stability of cocaine and opiates incorporated in hair.”
Q: What if I just shave it all off?
A: They will take hair from the armpits, and if that is shaved, from the groin. If they cannot get a good sample, you may be disqualified from consideration.
Q: Do I need to detox my body with detox drinks or pills?
A: Absolutely not. This will have no effect on the drug metabolites in your hair. You have to break open the hair shaft and get them out. This is best done with hair treatments, bleaching, and dyeing, or a permanent wave if you like.
Best Detox Products
- Old Style Toxin Rid with Aloe: Either this shampoo really can help get drug residues out of the hair, or they are engaged in a very lucrative advertising campaign. The stuff is expensive, at around $ 235. That makes it one of the most expensive liquids in the world since you only get 5 ounces. The reason it’s so expensive is that the original company, Nexxus, stopped making it. Then people started selling left-over bottles online and since it was rare, they jacked the price way up. So testclear.com saw an opportunity and made their own version which they say has the same ingredients as the original Toxin Rid with Aloe Shampoo. It’s up to you if you can afford to lay down what kinda money on shampoo, but for now, this is what people are talking about.
- Zydot Ultra Clean: Zydot Ultra Clean is well-trusted and more affordable than Old Style Toxin Rid with Aloe. It is used in both hair detox
A study in the International Journal of Legal Medicine in 2000 tested Zydot and found
“…a slight decrease in drug concentrations could mostly be observed e.g. cocaine (n = 10) –5%, 6-MAM (n = 12) –9%, morphine (n = 12) –26%, THC (n = 4) –36% (Röhrich, Zörntlein and Pötsch).”
Drug metabolites were not brought below the level of detection with just one wash with Zydot, but they did decrease a little. That’s all you need your shampoo to do with the Jerry G method, as the bleaching and dyeing is going to remove most of the drug residues.
We will be waiting on a scientific study done on Old Style Toxin Rid to see if it’s worth the cost.
If you had a hair drug test coming up, your best bet is it treat your hair to a round of bleaching and dyeing. If that’s unsuitable, you might use the Macujo Method. The controversial part is the $ 235 Old Style Toxin Rid with Aloe shampoo. Mostly, it will just make you feel more confident if you drop that kinda money on shampoo. If that’s not to your liking, just use the Zydot anywhere it says to use the Toxin Rid in either of these formulas. Someone has cleverly inserted a ridiculously expensive shampoo into both of the major methods of getting drug metabolites out of the hair. In the studies we have reviewed, none of them used any special detox shampoo, so if you don’t really have the money, just get use any good shampoo in its stead. The science is behind you, just bleach and dye. Good luck.
