Hair follicle drug tests have become a popular technique for identifying long-term drug use, which is why people must learn how to beat this specific test. As compared to urine tests, which can identify drugs in the system for only a few days, hair follicle drug tests can identify drug use for up to three months. These tests are relatively more difficult to beat as they have a longer detection period. This comprehensive guide will help understand the testing process, how long the drugs will show up in the hair, and how to pass a hair drug test.
Hair follicle drug test is a process in which hair samples are taken from the head or other parts of the body. The hair sample is analyzed for the presence of drug metabolites that are still present in the hair after drug use. When drugs enter the bloodstream, they circulate through the body and reach the hair follicles where they are deposited as metabolites, thus becoming part of the hair shaft. Since hair grows slowly, it is possible to identify these metabolites in the hair for a relatively longer period.




The main and most obvious reason why organizations have embraced hair follicle drug tests is that this test can detect drugs in the body for a long time. Urine and saliva tests only show recent use and are not suited for long-term monitoring. But a hair test enables an employer or a legal entity to determine the use of drugs for 3 months.
In hair follicle testing, the detection of drugs is quite flexible, since it is capable of testing for numerous substances. Below are some of the most commonly detected drugs:
Hair follicle testing has a long detection window, which is something that makes it stand out from the rest. Unlike other drug tests, where the test result will only show drug use for a few days or weeks, hair follicle tests will provide a look back period of several months. The average detection period therefore ranges from 90 days, but the time may differ depending on the rate of hair growth of the individual as well as the length of hair sample taken. Another reason is that body hair grows slower than scalp hair, thus a sample of body hair can possibly show the use of drugs over a longer time.
When analyzing hair samples, laboratories set up cutoff levels in order to draw a line between positive and negative. Any test result above the limit of the cutoff level will be taken to be positive, and this will mean that the person has been using the drug. However, if the test result is below the cutoff level, it will be labelled as negative, even in the presence of a little amount of drug metabolites.
Here is an example of common cutoff levels used in hair follicle drug testing:
It is also crucial to understand cutoff levels, as some individuals who use drugs in small amounts will have undetectable levels of them in their system.
Some of the things you should know to help you when preparing for a hair follicle drug test includes the following. Below are the steps involved:Below are the steps involved:
Factors That Affect Drug Detection in Hair
The ability of a hair follicle drug test to detect drugs can be influenced by several factors, including:
It is vital for one to understand that there are many myths and misconceptions about the hair follicle drug testing. Such myths can make people try out futile or even dangerous techniques in the hope of passing the test. Below, we debunk some of the most common myths:
The biggest myth about hair follicle tests is that shaving your head would help you pass this test because there would be no hair to test. But, if no scalp hair is present then testers can easily collect body hair (from either arms, legs, chest or back). Also, if you arrive to the test with no hair on your head at all, the testers may become suspicious and offer you to take a blood or a urine test.
Bleaching on the other hand will assist in minimizing the levels of drug metabolites in your hair, but it will not be fully eliminated. They are metabolites of the drugs which are deposited at most layers of the hair cortex, and simple bleach does not have the ability to reach these layers. To increase passing rate, one must use bleach with a detox shampoo or an alternative technique with the aim of eliminating metabolites within the cortex.
Some individuals opt to use apple cider vinegar, baking soda, or lemon juice, expecting that it is possible to beat a hair follicle drug test. Unluckily, these remedies wash only the surface of the hair and these treatments do not go deep enough to eliminates the drug’s metabolites of the cortex. Although, such remedies may be helpful for external toxins, they shall be of no use if you are in need of passing the hair follicle test.
Actually, some individuals may consume detox drinks for the purpose of beating urine drug test, but they do not have any impact on hair follicle test. Detox drinks aim at clearing drug metabolites from urine within a short period of time, but they don’t play any role in clearing the metabolites in hair. When cleaning your hair before a hair follicle test, concentrate on hair detox shampoos and other products developed for the purpose of hair cleansing.
Here are some of the general approaches and detox procedures that individuals employ in hope to clear the hair follicle drug test. Here are some of the most effective approaches:
Among all the methods of hair detoxification, the Macujo Method is the most popular and widely practiced. It is a complex method that is said to run for several steps with the aim of penetrating the hair cuticle to extract the metabolites from the cortex. The process is quite rigorous and should be done carefully because some people have complained of effects such as itching on the scalp or harming their hair.Here’s a step-by-step breakdown of the Macujo Method:
Another commonly used technique is the Jerry G Method, where hair is treated with bleach and dye to erase metabolites of the drugs. This method is a bit risky, but some individuals using it report it effective in making them pass hair follicle drug tests.
Here’s how the Jerry G Method works:
It is crucial to understand that bleaching and dyeing can cause hair damage, thus before applying this technique, the risks should be considered.
One of the best ways to pass a hair follicle drug test is by using the hair detox shampoo. Below are some of the best products available:
This is regarded as one of the best detox shampoo on the market that will help you pass a hair drug test. It has high concentrations of propylene glycol, which aids in the penetration and extraction of drug metabolites in hair shafts. It is most recommended when used with the Macujo or Jerry G methods of washing and treating the hair.
Wet your hair thoroughly.
First, spread Macujo Aloe Rid Shampoo thoroughly throughout the hair and then massage the scalp gently.
Allow the shampoo to remain in your hair for between 10 and 15 minutes.
Rinse with lukewarm water.
Along with the other detoxifying techniques, people apply Zydot Ultra Clean Shampoo to get a deeper cleaning of the hair. It operates through the elimination of compounds such as oil and dirt on the surface of the hair, making it easier for other products to eradicate drug metabolites.
If you know that you have a hair follicle drug test coming up, there are several steps you can take to prepare and increase your chances of passing:
Stop Using Drugs Immediately: The moment you get to know that a particular test is forthcoming, do not indulge in the use of substances that may make you test positive. The longer you go without using them, the better your chances at getting the levels of drug metabolites in your hair down.
Start Detoxing Early: It is recommended to start using detox shampoos or one of the mentioned above detox procedures as soon as possible. The longer you take in the process of detoxing your hair, the better it becomes to you as an individual.
Maintain Good Hygiene: Daily washing of hair even with normal shampoo will help to some extent in the reduction of external interferences. This will not clean the cortex of drug metabolites, but will at least keep the whole organ clean and can sweep off other toxins on the surface.
Follow Instructions Carefully: Most of the time when you are using the Macujo Method or the Jerry G Method or any other detox shampoo, make sure that you read through the instructions of the shampoo carefully. Failure to follow all steps or taking shortcuts is likely to compromise the process of detoxification.
Avoid Hair Products on the Day of the Test: On the day of the test, do not use any hair product such as gel, hair spray or conditioner as this might make the invigilator to suspect you.
As for passing a hair follicle drug test, it is not something very easy to do, but not something impossible either. When you have an understanding of how the test works and applying the best detoxification methods such as the Macujo or the Jerry G Method, your chances of passing will be much higher. However, there is no method that can assure one that he or she will pass the test, and the only sensible approach is to avoid any form of drug use in the first place.
