The Ultimate Guide – Pass Your Hair Drug Test

Being asked to perform a hair drug test can be quite scary. If you have already searched around for solutions, you may think you don’t have a chance. While the hair test is the more difficult to pass than the urine or saliva, it is possible. In this article, we review the basics of the test, and then dive into four ways you can pass the hair follicle drug test.

Hair 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, hair 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 the hair follicle tests (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?

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 hair 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.

4 Ways To Pass Your Hair Follicle Drug Test

Detox Shampoo

However, only special shampoos work, and not every brand that claims to get the job done is a good choice. Here are a few recipes that have been tested by many people.

Aloe Rid by Nexus – the old formula used to be quite popular, and you should search for it, if you want to get the same results as others.

TestClear – again, the old formula is recommended, but be aware that this brand is not sold for cheap.
As a rule of thumb, try to stay away from products that are simply too cheap to be true. Expect to pay at least 20 dollars, if not more, for a bottle containing a shampoo that works.

Shave It All Off

Since that time limitation is just one week, the simplest method at your disposal seems quite simple and handy: you should just shave every inch of your body, including your head, and you will get rid of the problem. Of course, keep in mind to stay away from drugs for one week before the test.

This may sound simple, but it is actually a bad course of action. Why? First of all, because your employers will see you all shaved just before a drug test, which will make them very suspicious of you. Second of all, because you may be subjected to a blood or urine test instead that will show if you have consumed drugs recently.

Home Concoction

With so many people getting tested for drug use, it is nothing out of the ordinary for them to search for methods they can use at home.

One popular method is called Growman or Macujo, and it is a blend of salicylic acid and vinegar. Another is called Jerry G, and it involves the use of bleach. Apparently, these active substances would be able to remove a certain metabolite from your hair that shows traces of drug use in the hair follicles.

A word of advice is recommended: these methods have not been thoroughly verified, so it is unclear whether they work or not.

Total Detox Friend

The most popular is called Hair Detox Friend and they have been in this business for over 10 years, which should count for something.

What does the program offer? First of all, you will be taught about different methods of detoxing your hair. Then you will be guided towards a personal counselor that will handle your case in particular in order to help you get over the hair drug test with flying colors.

With decent pricing, and a fair money back guarantee (60 days), they can be quite the solution you are after.

Basics Of The Hair Follicle Drug Test


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

  • Cocaine
  • Marijuana
  • Heroine
  • Morphine
  • Ecstasy

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 Hair 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 hair grows more slowly, 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 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.
