Dude, having to take a hair follicle drug test fucking sucks; it’s a terrifying experience. If you’ve been reading the forums and other websites, then you probably feel hopeless. Everyone makes it seem impossible to pass it.

Look, I understand how the shitty the feeling can be. Maybe you just got offered your dream job, only to hear the words, “We’d like to hire you, but you just need to pass your drug test first. Trust me, I’ve been there before and it’s not fun.

But before you give up, here are three proven ways you can pass your hair follicle drug test.

3 Ways To Pass The Hair Test

Shave It All Off

Example: You smoke a blunt on Sunday night. You wake up Monday morning and shave your entire body. Let’s say it’s Friday now and you have a tiny bit of hair growth since the shave.

That hair will probably not contain traces of drugs. But once it becomes Saturday or Sunday (more than 5-6 days passing) then they start becoming present.

Is this option realistic? Well, you’ll have to be the judge. What’s the chances you get asked to take a hair drug test and then randomly decide to shave your entire body the next? I’ve never tried this, and I don’t imagine it would be easy to keep a straight face through the process.

Aloe Rid Detox Shampoo (Best Option)

image of aloe rid detox shampooDespite what you might have read on online, there are a few rare (yes, quite rare) hair detox shampoos that are effective. Most hair detox shampoos will fail because they cannot get inside the hair follicle. This is where the small amount of toxins hide (making them accessible to the testing laboratory).

The Aloe Rid shampoo is one of the few that can get inside and remove the bad toxins. We were able to find it at TestClear.

UPDATE: 05/28/2016

The price of Aloe Rid has substantially jumped up in price due to the high demand for the product. While we know it’s the best option on the market, we know it’s a steep price to pay.

Keep this is mind: Yes, the product is expensive. But ask yourself what you stand to lose. If you’re going for a dream job that’s going to pay you more than you’ve ever made before, it’s probably the right choice. We’ll leave the decision up to you.

Light User Loophole

This method only works if you’re a light smoker. Note: The following example assumes you smoke weed. The hair exam is not designed to pick up small or occasional use.

What does that mean?

Let’s say you smoked a bowl (only a bowl) around 30 days ago. Then you smoked the same amount around two weeks later. It’s possible that you consumed such a low dosage that your test result will come back undetected. You see, the labs (with regard to hair tests) are designed to find patterns of marijuana and other drug usage.

If you smoked a bowl 7 days in a row, or worse, even more weed was smoked, then you are almost certainly screwed.

Hair Follicle Drug Test Facts

A hair drug test is often used to determine use of illegal drugs for pre-employment purposes. The test is chosen over the urine test for a few reasons. First of all, on a biological level, follicles retain drugs better than urine and blood. Second, hair samples are more likely to offer accurate results when compared to the urine analysis.

Third, it is considered that hair tests are more difficult to beat than other tests. This is because a sample can be harvested from the person being tested without invading their privacy. Also, compared to urine tests, hair samples cannot be falsified as easily, as synthetic urine.

There are various products designed to help you pass (mostly sold online). They claim to offer you the best chances to pass such a test, but we recommend you read this guide before purchasing any product.

Is It The Best Test?

image of hair drug test factsIt all has to do with the biological processes taking place in your body. Urine and blood, for instance, are renewed constantly, but the hair that grows on your head or your body lasts for a long time and you should remember that its growing process starts from within the scalp. This means that your hair can store information on your drug use history dating several months back in time.

As far as the history of drug use is concerned, most lab tests can detect heavy usage of drugs within the last 90 days. This is the longest duration for which a drug test can verify drug use.

An interesting enough fact about hair follicle drug tests is that they can say, with approximation, when the last heavy use of drugs has occurred. The upside is that the lab can tell you have been clean lately, but this may work or not in your advantage.

Remember that these tests will try to identify the last session of heavy drug usage. This means that a few smokes a few weeks ago will not be obvious in the sample, which may be a good thing for your peace of mind.

What Does Testing Day Look Like?

First of all, you have your sample taken. Usually, someone from the lab will cut a small portion of hair from
your scalp.

Next, the sample will be sent to a lab, and there, the people hired by the lab will do various tests to identify or not the drug use. A few days later, you will get the results from the lab and you will learn if you passed or not.

The Basics


One thing that may scare you about hair drug tests right off the bat is that labs say that their results are 99% accurate. This sounds scary, indeed, but the truth is the number is not that high. Like in the case of urine and blood samples, there are various factors that can come into play and determine different results.

Drugs Tested

Certain drugs can be traced in your hair through these tests. Here is a list of common drugs identified through hair drug tests (information found at

Testing Period

You may be interested in some time limits for drugs to get inside the hair follicles. For instance, the hair on your scalp takes about one week to grow from its inside roots above the scalp. That is when the traces of drugs will appear in case of a test, too.

Other Spots

That is a very good question. In case you don’t have enough hair on your head, the lab will request a sample from other parts of your body. Body follicles grow slower, so if you have engaged in heavy drug use just before a test, this may not appear in the tests.

However, there is a silver lining to all these. During recent years, the accuracy of such tests has been on decline, and that may have happened because of the appearance of more efficient ways to really dodge them.

Test Yourself At-Home

There are a few drug testing companies that are more popular with employers than others. For instance, Psychedemics is a company well known in the US, and, in case you hear that you will have your hair follicle analysis test done by them, you should prepare very carefully for the test.

Also, if you want to determine if you have any reasons to worry, it is highly recommended to purchase a test for home use and test yourself.
