Table of Contents

At this point of time when the consumption of drugs is at an all-time high, people often undergo or face drug tests in one way or the other.

One such system of determining the presence of drugs in one’s body is the Hair Follicle Drug Test.

Hair follicle drug tests are commonly used methods for detecting drug use over an extended period. Unlike in most other drug tests, the detection window is comparatively longer, accommodating up to 3 months.

Whether you are facing an employment screening, legal requirement, or personal concern, the prospect of passing a hair follicle drug test can be crucial. It is very important to be well aware of strategies and precautions you could take that may elevate the probability of you obtaining a negative result.

In this article, we will provide you with effective information and ways to ace a hair follicle drug test.

What is a Hair Follicle Drug Test?

The hair follicle- a shaft through which the hair sprouts out is a major determinant of drug consumption. Therefore, it has become an instrument of analysis to check for drugs using the hair follicle drug test.

A hair follicle drug test, sometimes referred to as a hair analysis or a hair drug test, is a form of drug testing procedure that looks for drugs or their remains in a person’s hair follicles. It is frequently used to determine whether someone has used drugs within the 90 days prior to the test.

It’s salient to understand that a hair follicle drug test cannot determine the specific time of drug use, as the drugs become detectable only after they have been metabolized and incorporated into the hair follicle. Additionally, it is not influenced by external factors like shampooing or exposure to second-hand drug smoke.

Hair follicle tests are often used by employers, law enforcement agencies, and athletic organizations as a part of their drug testing programs.

Top 3 Effective Ways to Pass a Hair Follicle Drug Test

These methods involve abstaining from drug use and employing specific techniques and products aimed at minimizing the presence of drug metabolites in the hair follicles.

Understanding these procedures can assist you in making informed decisions and taking the necessary precautions to prepare for a hair drug test.

Breaking the Myths About Hair Follicle Drug Test

Let’s make the read more interesting by talking about something that’s pretty unconventional- “Myths”. Hair Drug Tests are very often connected with multifarious theories or in simple terms, myths’. Understanding these misconceptions or myths is important for obtaining accurate information about hair drug tests. Here are some common misconceptions:

Immediate detection of recent drug use

One common misconception is that hair drug tests can detect drugs immediately after use. In reality, it takes around 5-10 days for the components of the drug substances to be incorporated into the follicles of the hair. This harms the actual purpose of the test since any recent drug use especially within the past two weeks may not be detected during the hair drug test.

External contamination leads to false positives

Another misconception is that external exposure to drugs or environmental contamination can cause false-positive results in hair drug tests. While external contamination is a concern, laboratories conduct extensive testing and analysis to differentiate between external contamination and actual drug use. Confirmatory tests can help identify and rule out false positives.

Shaving or cutting hair ensures a negative result

One of the most widespread myths is the idea that shaving off the hair or trimming it as short as possible could somehow affect the outcomes of a hair drug test. Several test-takers are unaware that hair from any area of the human body can be utilized for screening for drugs if specimens from the scalp cannot be obtained. There is no monopoly of the hair from the head alone to partake in the hair drug test.

Furthermore, suspicion can act as a villain especially if it’s noticed that there have been quite some efforts done to alter the results. They could even fail your test out of this factor.

Hair detoxification methods are foolproof

There are numerous products and methods claiming to detoxify hair and remove drug metabolites. However, the effectiveness of these methods is not scientifically proven and remains a topic of debate. Some detoxification products may even raise suspicions during the testing process.

Only recent drug use can be detected

While hair follicle tests have a longer detection window compared to other testing methods, they are not capable of detecting drug use immediately prior to the time frame covered by the test. The detection period depends on the length of the hair sample but generally covers up to 90 days.

All drugs are equally detectable

Drug tests using hair follicles are largely made to find drugs that are often misused, like marijuana, cocaine, amphetamines, opiates, and PCP.

Yes, it is accurate that this test may identify a wide variety of substances; nevertheless, it must be remembered that there are almost limitless versions of drugs on the market, particularly if you look at the constituents or subtypes of these drugs.

Understanding these common misconceptions about hair drug tests is important for obtaining accurate information and making informed decisions. Now you would not want to appear for the test after shaving your entire head hair off!

Why are Hair Follicle Drug Tests conducted?

Hair drug tests are conducted for various reasons, including:

Workplace drug testing

It is very common among many employers now, to use hair drug tests on their employees. The long detection window helps employers especially during pre-employment screening since it can help them detect the candidate’s history with drugs.

Ongoing employee testing programs are another place where hair follicle tests play a salient role. It is important for the employers of the company to ensure that the welfare and productivity of the workplace are not hindered.

Legal and forensic purposes

Hair drug tests are often used in legal and forensic settings to provide evidence of drug use. They may be required in cases such as child custody disputes, probation monitoring, or criminal investigations where drug use is relevant.

Rehabilitation and Treatment Programs

Hair drug tests can be used in addiction treatment programs to monitor an individual’s progress and verify their adherence to sobriety. Regular testing can help support recovery efforts and provide accountability.

Sports Organizations

Some sports organizations and anti-doping agencies utilize hair drug testing to detect the use of performance-enhancing substances or recreational drugs. These tests help maintain fair competition and ensure compliance with anti-doping regulations.

Personal or parental concerns

Individuals or parents may choose to undergo hair drug testing out of personal concern, or suspicion, or as a condition for maintaining a certain environment, such as drug-free homes or custody arrangements.

Medical purposes

In certain medical contexts, hair drug tests may be used to assess a patient’s drug history, especially if there are concerns about medication adherence or substance abuse that could impact medical treatment.

Since they have a longer detection window as opposed to other drug testing techniques, hair drug tests are preferred in many of these circumstances. To analyze past drug usage and assess the magnitude of a person’s history of substance misuse, the test could provide a chronology of drug use patterns.

What Factors Make Hair Follicle Drug Tests Favorable?

There are quite a few factors that act as tools of favorability when it comes to hair drug tests. Especially in recent times, along with advancements in technology, these tests have become easier and act as a much preferred one to attain the purpose of drug detection in the bodily system. Here below are a few factors that make hair drug tests a favorable one.

Long detection window

Unlike a saliva test or a urine test or even a mouth swab test, the detection window in the hair follicle drug testing is much longer. In contrast to a month-long or a couple of days detection window in other drug tests, the window here in hair follicle tests traces drug traces up to the duration of 3 months to the date of the test. This makes it useful for assessing long-term drug use history.

Deterrence and prevention

During the stages of pre-employment screening or even for periodic casual drug testing programs, this method of using hair follicles for testing for drugs is very common and popular among employers.

The prime motive behind the implementation of such tests is the development and creation of a work environment void of any presence of drugs or substances. The employers can thus discourage the members of the company to promote the welfare and well-being of everyone in the workplace. This can help enhance safety, productivity, and overall workplace morale.

Compliance monitoring

As stated earlier there is no compromise on the fact that in certain professions and industries, such as transportation, aviation, law enforcement, healthcare, etc., a drug-free environment has to be ensured. It is crucial due to safety as well as concerns of welfare and productivity. Hair follicle testing can be used to ensure compliance with drug-free policies, especially for employees in safety-sensitive positions.

Forensic purposes

Hair follicle testing is also used in forensic investigations and legal proceedings. It can provide objective evidence of drug use over an extended period, which can be valuable in criminal investigations, custody battles, and probation monitoring.

Athletic drug testing

Hair follicle testing is employed in sports organizations and anti-doping agencies to detect the use of prohibited substances by athletes. Since it can detect drug use over a longer period, it can help identify athletes who may have engaged in doping practices and ensure fair competition.

The essence of it lies in the need to ensure an equal and justified participation of athletes across various events.

Less Chances for Adulteration

Since the detection window is long, unlike most other drug testing systems, generic points like abstaining from drugs or drinking plenty of water, etc, don’t help much. Of course, there are methods to perform adulteration; however, it isn’t very easy like in other drug testing systems.

How Does a Hair Follicle Drug Test work?

The entire procedure may appear self-explanatory, and to a certain extent, it is. To identify the existence of drugs or their elements that have been thoroughly absorbed into the hair shaft as it grows, a hair drug test analyses a sample of hair. Here is a step-by-step explanation of how a standard hair drug test operates:

Step 1: Sample Collection

A certified collector or technician will collect a hair sample from the individual being tested. The hair is usually taken from the back of the head, close to the scalp, to ensure consistency in hair growth patterns.

Step 2: Sample Preparation

The collected hair sample is typically cut close to the scalp to provide the most recent growth for analysis. To ensure accuracy in the test a good amount of hair is required in contrast to the notion that just one strand would work well for the test. Usually, in most cases, about 1.5 inches which equal around 100-120 strands, is needed for an accurate test.

Step 3: Washing

To remove any external contaminants, the hair sample is washed with a specialized detergent to eliminate substances like oils, dirt, or drug residues that may be present on the hair surface.

Step 4: Testing Process

Lab testing is done on the cortex, the last remaining inner section of the hair. To locate and measure the presence of particular drugs or their byproducts, various testing techniques are employed, such as mass spectrometry and enzyme-linked immunosorbent assay (ELISA).

Step 5: Detection and Interpretation

The hair specimen is examined by laboratory technicians for the presence of particular drugs or their compounds. Each drug has a unique detectable limit, and if a drug’s concentration or its residue’s concentration is higher than that limit, the test is declared positive.

Step 6: Reporting of Results

Once the analysis is complete, the laboratory generates a report detailing the drugs detected, their levels (if applicable), and whether the test result is positive or negative. The report is then provided to the organization or individual that requested the test.

What are the Limitations of the Hair Follicle Drug Test?

Drug tests performed on hair follicles are thought to be a trustworthy method to identify drug use over a longer duration of time. They do, however, have some restrictions that must be considered:

Detection window

Drug usage can be identified over a lengthy period, usually up to 90 days, using hair follicle tests. They do, however, do poorly in terms of identifying recent drug use. A hair test might not discover drug usage during the last week or two because it takes about 5–10 days for drugs and their components to be absorbed into the hair follicles after use.

Inconsistent Drug Incorporation

Hair as an instrument is very variable in nature. Each and every person will possess features unique to themselves. This is reflected in the way consumed drugs are incorporated into the hair follicles. Personal factors play an imminent role in determining the presence of drugs in the system. Right the type of hair the length, the ingredients present in the drug, and the frequency of usage affect the results. Some individuals may have slower drug incorporation, leading to a potential delay in detection.

External Contamination

External factors can contaminate hair and potentially lead to false-positive results. For example, drug residues from environmental exposure or contact with drug users may be present on the hair surface. However, confirmatory testing can help distinguish between external contamination and actual drug use.

Limited Drug Coverage

Hair follicle tests are primarily designed to detect specific drugs such as marijuana, cocaine, amphetamines, opiates, and PCP. They may not be as effective in detecting certain drugs like benzodiazepines or synthetic cannabinoids. Additionally, the ability to detect low levels of drug use can vary depending on the substance.

Inability to Determine Frequency and Dosage

While hair follicle tests can indicate the presence of drugs, they cannot determine the frequency or dosage of drug use accurately. This information is crucial for understanding the patterns and severity of drug use.

Limited Temporal Resolution

Hair follicle tests provide a historical overview of drug use over an extended period. They cannot pinpoint the exact timing of drug use since drug metabolites accumulate in the hair over time. As a result, it is challenging to determine when drug use occurred within the detection window.

Lack of Racial Specificity

There is historical information to show that racial differences may affect how drugs are incorporated into hair follicles. Although further intensive study is required in this area, this may possibly result in inaccuracies or irregularities in test results.

When evaluating the outcomes of a hair drug test, it’s crucial to keep these limits in mind.

Can Every Substance Be Detected Using Hair Follicle Drug Test?

Drug tests on hair follicles are made for detecting particular drugs, but they don’t work for every substance. Drugs that are frequently abused are often included in the conventional panel for a hair follicle drug test, including:

Marijuana (THC)


Amphetamines (including methamphetamine)

Opiates (including heroin, morphine, and codeine)

Phencyclidine (PCP)

Considering they can be detected in hair for a longer period than other drugs, these drugs are strictly included. But not every drug can be accurately identified by a hair follicle test. Conventional hair drug testing frequently omits a bunch of drugs. They are:

Benzodiazepines: A group of drugs consisting of sedatives, tranquilizers, and anxiety-reducing meds are known as benzodiazepines. Although they are typically excluded from the typical hair drug test panel, additional tests can be run to identify particular benzodiazepines.

Synthetic cannabinoids: Also referred to as “synthetic marijuana” or “Spice,” synthetic cannabinoids are manufactured medications that replicate the therapeutic properties of Cannabis. Synthetic cannabinoids could fail to be as consistently or reliably detected in hair follicle tests as real cannabis.

Designer drugs: Synthetic chemicals made to resemble the effects of illicit drugs are referred to as designer drugs. It is difficult to include these drugs in typical hair drug testing because they frequently endure repeated chemical alterations to avoid detection.

It’s crucial to remember that the precise drugs screened for can change based on the testing facility or the particular needs of the organization administering the test.

Precautions to be Taken Before Taking a Hair Follicle Drug Test

To get results that favour you, it’s advantageous to follow some guidelines before undergoing a hair drug test. Here are some of the safety measures you can implement:

Reduce drug exposure: Try to limit interaction with drugs or drug users in the days preceding the test to reduce the chance of external contamination. This includes keeping away from marijuana smoke or being around an individual who is using drugs.

Keep your surroundings tidy: To lessen the likelihood of being exposed to drugs in the environment, keep your workplace and living areas tidy. Avoiding touching objects or surfaces that could have traces of drugs on them to be on the safe side.

Be cautious while getting your hair treated: Some hair procedures, like bleaching, perming, or dying, can tamper with the test results or impair the authenticity of the hair sample. It is best to discuss any fresh hair treatments with the testing facility and to abide by their recommendations.

Let the testing facility know if you’ve recently had hair treatments: It’s crucial to let the testing facility know if you’ve recently had hair treatments. They can accurately interpret the outcomes and, if required, implement the appropriate safeguards with the use of this data.

Adhere to instructions: It’s essential to adhere to the testing facility’s directions concerning sample collection. It might also include the length of hair needed, how to correctly gather the sample and any particular directions for sample packaging or shipping.

FAQs About Hair Follicle Drug Test
