How to Pass a Hair Drug Test? Tested Method and Products

The hair follicle drug testing is now commonly used in various activities such as in the employment sector, sports, and in legal issues. It is crucial to understand how to prepare for and pass a hair drug test especially if one has to face the test. This guide provides you with all the information you need concerning the right strategies and products to use in order to pass the hair drug test.

Introduction to Hair Drug Testing

Hair follicle drug testing is considered to be very effective particularly because it can detect drug use histories spanning at least 90 days. While urine or saliva tests identify the use of drugs within the last few hours to days, hair follicle tests identify drug metabolites that have been absorbed in the hair follicle over a period of time. This makes it a preferred method for employers and legal authorities when they require to determine the history of a person in substance use.

Understanding Hair Follicle Drug Testing

Hair follicle drug testing involves collection of hair, preferably from the head, and analyzing it in order to determine the presence of drugs. The process is meticulous and involves several steps to ensure accurate results:

➔  Sample Collection

To obtain a hair sample for drug analysis a competent specialist cuts a strand of hair near the root, by cutting it no less than 1. 5 inches long. In case the head hair is not enough in quantity or meeting the desired quality, body hair can always be considered as a good substitute. Gloves are used by the technician during collection in order to avoid interferences which could alter the results on recent drug exposure.

➔  Analysis

Following this collection process, the hair test sample is then cleaned in order to eliminate external contaminants. It is then dissolved to release drug residues trapped within the hair shaft. These residues are then quantified using other techniques such as the enzyme immunoassay (EIA) and the gas chromatography-mass spectrometry (GC-MS) to identify the specific drug in the sample.

➔  Detection Windows

Compared to other drugs testing methods, hair drug test detects long-term drug use patterns, hence why it is preferred. The detection window for different drugs can vary significantly based on the frequency of use:

  1. One-time use: Drugs can typically be detected in hair for up to 7 days after use.
  2. Occasional use: For infrequent drug users, the presence of drugs within hair can be traced up to 30 days after usage.
  3. Regular use:  Hair testing can confirm the use of drugs in people who consume it frequently up to 90 days after using the substance.

Understanding these detection windows is crucial for interpreting hair drug test results accurately and comprehensively. It enables professionals to assess an individual’s drug use history more effectively based on the timeline of detection provided by hair analysis.

Factors Affecting Test Results

Several factors can impact the accuracy and reliability of hair follicle drug tests:

1.   External Contamination

Hair can retain drug residues from external environment such as second hand smoke, thus leading to false positives.

2.   Metabolism and Hair Growth Rate

The metabolic rates and hair growth rates are likely to vary from one person to another, and thus the rate of drug deposition in hair shafts.

3.   Type of Drug Used

Also, as observed in the study, the concentration and the time period that each drug stays in hair varies.

Methods for Passing a Hair Drug Test

When facing a hair drug test, individuals often explore various methods to increase their chances of passing. These methods range from natural detoxification approaches to the use of specialized products designed to cleanse the hair of drug metabolites. Understanding each method in detail can help individuals make informed decisions based on their specific circumstances and the type of test they are facing.

1. Natural Detoxification

Natural detoxification is defined as abstaining from using the drug again and possibly allowing the body to metabolize any remaining contents of the drug in the system. This method is based on taking the required amounts of vitamins and minerals, drinking water, being physically active, and sleeping for the required hours. Detoxification in its natural sense aims at cleaning the body, including the hair follicle, for there to be fewer particles of drugs in the body after several days.

This form of detoxification depends on the type of drug used and the frequency of use, the rate of metabolism, and the health of the individual. The removal of drug metabolites through natural cleansing may take several weeks to several months from the hair follicles.

2. Detox Shampoos

Detoxification shampoos are made specifically to eliminate drug metabolite and other substances from the hair. The most popular product within this category is the Macujo Aloe Rid Shampoo. Macujo Aloe Rid Shampoo has attracted major attention due to enhanced components of propylene glycol, aloe vera, salicylic acid and the effective surfactants. Aloe vera moisturizes the hair and shields it from damage during the rigorous detoxification process, while salicylic acid prepares the outer layer of the hair cuticle for the penetration of the cleansing agents.

Macujo Aloe Rid shampoo is especially known for reducing hair drug test failures.

This shampoo has been recommended by many people to pass drug tests because when used in combination with other products as part of the Macujo method formula, this shampoo works magic.

These products are marketed as being in a position to support other types of cleansing and may aid in the expulsion of metabolites that may be lodged in hair follicles.

However, it should be noted that the use of such supplements may bring benefits to the body, help the natural cleansing process, etc., to help pass a drug test but unfortunately, it is not scientifically verified, and the effectiveness depends on various factors such as metabolism, type of substances, etc. Consequently, although the intake of dietary supplements may be an important element of a detoxification plan, it is recommended to use them in conjunction with effective detoxification techniques, like the use of specialized shampoos or the avoidance of substance use, to increase the chances of passing a test.

These masks have the active ingredients with the aid of which when used in cooperation with detox shampoos it assists in cleansing the hair follicles. These masks remove build-up residues and environmental impurities and make the detoxification process more effective, ensuring that hair strands are clean and healthy.

6. Home Remedies and DIY Methods

Lemon based remedies include rinsing the hair with lemon, washing hair with a mixture of lemon and baking soda, and washing hair and scalp with apple cider vinegar. However, it should be noted that although these methods are efficient and frequently applied in practice, their efficiency is not always guaranteed.

Factors such as individual metabolism and the specific substances involved influence their reliability. It's advisable to approach these remedies cautiously and consider combining them with proven detox methods like specialized shampoos to enhance the likelihood of achieving clean test results.

Common Myths and Misconceptions

There are so many myths that surround hair drug testing, and how one can beat these tests in the market today. It's important to understand these myths so you can prepare effectively:

➔  Shaving Hair

Some candidates think that the procedure of shaving their heads will help them to pass their hair drug test. But it is not right because metabolites of drugs accumulate not only on the surface of the hair shaft, but inside it as well. This means that even if you cut all your hair and get a bald head, the hair that grows back will have the same history as the former.

➔  Immediate Abstinence

To pass any drug test, it is necessary to cease taking drugs; however, just stopping the consumption of the substances under test is not sufficient. The metabolites of the drugs can be saved for a longer period in the hair. If you want to get rid of them, it is necessary to apply the products that will help to clean the hair properly.

➔  Short-Term Abstinence

Detoxifying the body and abstaining from the drug for a few days prior the test is good but may not be enough. That is why it is advised to abstain from drugs for a longer time and apply effective methods for detoxification. Such measures may include the use of special shampoos or treatments that help to wash out the residual drugs from your hair.


Passing a hair drug test means preparing well for it and using the right hair cleansing products and procedures. With adequate knowledge of the hair follicle testing procedures, proper choice of detox products, and indeed following the use of procedures such as the Macujo and Jerry G. methods, one has enhanced chances of passing the tests with ease. It is always advisable to seek professional advice or strictly follow the manufacturer’s guidelines in order to have the best result.
