What Is a Hair Drug Test?

An individual is tested for metabolites or drugs by taking a small sample of their hair. There is a method of testing that uses a hair sample that has been collected months after a drug has been consumed to detect it.

Other methods of drug testing, such as saliva or urine, are less accurate than hair follicle tests. While the hair testing method is, as a result, not as accurate as other methods of drug testing in terms of detecting recent consumption, it still has some benefits.

When drugs are used, they are absorbed into the bloodstream. Hair follicles have blood vessels, so the substance will be carried to different parts of the body by the medication. During the 90 days following the drug administration, drug traces can be detected in the hair follicles.

For individuals seeking to pass a hair follicle drug test, some may explore the use of specialized shampoos like Old Style Aloe Toxin Rid and Zydot Ultra Clean. These products are marketed as detoxifying shampoos that claim to help remove drug traces from the hair, potentially increasing the chances of passing the test.

How Does Hair Follicle Drug Test Work?

The body transforms the drug into substances called metabolites after consuming it. Metabolites can be produced as a result of the absorption of drugs by the body.

By analyzing hair samples, a hair drug test determines if you have used drugs, as well as the concentration and presence of drugs and their remains. The reason for major reason for this is drug residues can remain in the hair follicles for a long time.

For drug residues to get into the hair follicles, it usually takes between seven and ten days for them to navigate into the body. No matter how you consume the drug, it will enter your bloodstream every time you take it. The virus will spread to other parts of the body when it gets into the bloodstream, including the hair. Through the follicles of the scalp or the oil glands of the scalp, the drug can reach the hair.

In the course of growing your hair, the residue from the drugs will remain in it. As a result, the remnants will be trapped in your hair for many weeks, even three months. Aside from the hair on the head, the metabolites also flow to other body parts. It is also possible for hair to trap these elements in other parts of the body, such as the armpits.

To address this issue, individuals often turn to specialized shampoos like Old Style Aloe Toxin Rid and Zydot Ultra Clean. These shampoos are designed to help remove drug residues from the hair, providing a potential solution for those facing drug tests.

It is important to keep in mind that a hair sample taken from the body can reveal drug use up to a year in the past. Nonetheless, drugs can last up to 90 days in those taken from the head.

How Long Does Marijuana Stay in Your Hair Follicles?

Marijuana functions similarly to all other drugs, including staying in your hair follicles and lasting approximately 90 days. It is determined by the amount of time it generally takes hair to grow past the scalp which determines the drug detection window for hair follicles.

New hair grows within five to ten days after it is shed. A person’s hair also grows by around half an inch each month. For a follicle test, lab testers need 1.5 inches of hair from the roots. Hence, if you take the time to calculate, it’s easy to understand that it’ll take 90 days for you to get clean. The result of a hair follicle drug test is that if you are a marijuana user, you will test positive. Using products like Old Style Aloe Toxin Rid and Zydot Ultra Clean shampoos may help in the detoxification process.

So, how long THC stay in your hair also depends on the factors given below.

Body Mass Index

The fat cells of people with high BMI will retain THC much longer than those with low BMI. Similarly, people with a low body mass index (BMI) cannot store THC for a long time. They will, therefore, be able to eliminate the toxins from their body at a faster rate. If you fall into category one, you may require more detox products than the average person.


Depending on the gender, weed or THC remains in the hair follicles for a longer or shorter time. There is a tendency for females to have more body fat than males, and this can be attributed to the fact that they have a slower metabolism rate than males. It is therefore possible to detect cannabis for a longer time.


Cannabis is more likely to be excreted from the body by individuals with a high body metabolism. Toxins may be more difficult to eliminate from the body if your metabolism is slower.

Frequency and Way of Use

If you are a frequent user, your toxin level is high. That is why you need to have more time for cleansing. Also, there is an issue with your metabolism. When you are a rare user, your body claims THC as an undesired pollutant or even poison. If you are a frequent smoker, your body does not act like that due to habit. There is no alert, no reason to boost metabolism.

Also, there is secondhand smoke that allows residues to stay much longer.

When you consume marijuana instead of smoking it, the THC content in it stays in your system for a longer time. It is also more difficult to naturally cleanse your body of marijuana the more you consume. To increase your chances of passing test, you can use specialized shampoos, such as Old Style Aloe Toxin Rid and Zydot Ultra Clean, which can help you to clean your hair and pass the test successfully.

How Does Hair Drug Test Work?

A single hair strand is taken from your head and tested to determine if you are clean based on the condition of your hair follicles. The hair follicle is connected to the bloodstream via a blood vessel that runs through it. If you take THC or a toxin, your hair follicles will hold on to it for a while.

Check out the substances that hair drug tests can detect,

  • Cannabis
  • Cocaine
  • Opiates
  • Amphetamines

If you are wondering can a hair follicle test can detect one-time use, you should know hair follicle drug test can detect even one-time use.

Testing Process and Main Principle of the Hair Follicle Drug Test

It is based on the fact that drugs and their elements are incorporated with the hair as it grows as it is tested for drug use. Drugs enter the bloodstream when someone consumes or smokes them, and then slowly move to the hair follicle.

During the process of growing your hair, the substance is trapped within keratin fibres, which are located in the keratin areas of the shaft. An expert sends a hair sample for lab analysis to determine if the drug is present in the hair. Strands are divided into smaller parts and then dissolved in a solvent. Hair samples are being examined to extract the drug atoms present within them.

Immunoassays, which use antibodies to identify the precise substance and its constituent parts, are utilized in this test. Mass spectrometry and gas chromatography are used as supplementary methods as well. As a result of the technique, hair components can be separated from each other and toxins can be identified.

The lab determines the drug and its concentration levels by examining the hair sample, and it then generates the test results.

Main Principle of Hair Drug Testing

Detecting the time of the drugs in hair follicles and the elements present in them are the main goals of hair drug testing. There’s usually a 3-month period.

A hair drug test is not just difficult to pass, but it’s impossible in 24 hours. To increase your chances of passing a drug test, you need to use a detox product that is designed for detoxification. Two popular detox shampoos known for their effectiveness in preparing for hair follicle drug tests are Old Style Aloe Toxin Rid and Zydot Ultra Clean. In the latter half of the article, you will get to know more about hair follicle drug-testing shampoo.

Drug testing of hair follicles is a very common practice in the workplace. A system of criminal justice can also demands the use of it. It’s strictly forbidden to use drugs in these areas. The accuracy and reliability of hair drug tests make them popular among many organizations.

Although a few factors can influence the outcome, they are not the only ones. Among the factors considered is the amount of drug being used, the medication under test,  the person’s hair growth rate, and how often they use the drug.

What Happens During a Hair Drug Test?

It takes many steps to successfully conduct a hair follicle drug test.

Take a look at what you can expect from the test,

  • The hair follicle sample will be taken by an expert by cutting it from the back of your head. Usually, they take it from about 1.5 inches away from the scalp.
  • Hair samples might be taken from another part of a bald individual’s body by the laboratory expert.
  • Then it will be sent to the laboratory for washing and preparation.
  • A second confirmation test will be performed after the immunoassay lab test results are positive. This test is referred to as Gas Chromatography-Mass Spectrometry and is more sensitive than the previous test.
  • In the end, the final test will determine whether the previous one was accurate or not. If drug concentrations are present, it will also test them.

It is considered by several experts to be the most accurate method to test for drugs in hair. Besides detecting a wide range of drugs, it is also accurate.

How to Not Pass Hair Follicle Drug Test?

Hair follicle tests can be affected by a variety of substances. Before the drug test, review the materials you need to know.

 Poppy Seeds

Taking poppy seeds for a few weeks before your hair follicle test may cause it to fail. That’s because these innocuous little seeds contain morphine and codeine, both of which could show up on a drug test. Then again, it could be viewed as an innocent mistake– because we all know that poppy seeds are most commonly thought of in sweet and savory dishes! However, the reality is that individual tolerance to these two powerful opiates may vary so when it comes down to the potential risk versus reward in this situation, you should think twice before ingesting poppy seeds and running the risk not only of a failed test but also possible repercussions thereafter.

  Ingesting or Smoking Cannabis

THC can have a long-reaching effect on hair tests. So much so, that these drugs are among the quickest ways to fail them. The chemical compound influences the result meaning it can notoriously be detected by hair follicle testing even when it has been absorbed into blood and urine rather than being suspended within the strands. Consequently, traces of THC often linger in the body for much longer than expected. When seeking to remove these traces, individuals often turn to specialized detox shampoos such as Old Style Aloe Toxin Rid and Zydot Ultra Clean to help cleanse the hair of any residual substances.

Using Mouthwash Products

Sometimes it’s surprising to find alcohol in personal health and hygiene products. For instance, a common ingredient used for providing that minty clean feeling to our breath is ethanol, also known as grain alcohol. Ethanol has low toxicity levels compared to other forms of alcohol but its residue is still detected in hair follicles — which raises alarm bells for anyone who has recently been tested for drug use. The fact is if you go for a hair follicle test after using products that contain ethanol, you may be in trouble because of the traceable residual alcohol; including anything from mouthwash to vanilla extract.

Pills for Weight Loss

If you take weight loss pills that contain Phentermine, you might have a positive result if you have to take a drug test. Phentermine is chemically similar to amphetamines, which are commonly found in ADHD medications. For individuals planning on taking a drug test in the next couple of weeks, it’s not advisable to use any weight loss product containing Phentermine as it could cause you to fail your drug test.


CBD oil is not the only product that can affect a negative hair drug test result. The cannabis sativa plant is also a possible source of positive test outcomes. Hemp, known for its many beneficial properties, is simply a variant of cannabis. In just a few countries, marijuana edibles that contain up to 5% THC are available and legal to consume. If one uses these CBD products, it is possible that traces of THC remain in their body which could cause their hair drug tests to report unsatisfactory results.


Antidepressants such as Zoloft and Sertraline are available over the counter. Benzodiazepines, for example, can change a negative drug test result for most of these drugs. Sertraline and benzodiazepines may sometimes be misdiagnosed by tests. Therefore, if you fail a drug test, it’s possible to fail it after taking antidepressants.

You might wonder how the substances can have an impact on the hair follicle drug test detection times. A few components might show up in the drug test.

Misconceptions People Have About Hair Drug Tests

The ability to pass a hair drug test is somewhat misunderstood by many people.

Bleaching Hair

When it comes to passing a hair drug test, many believe that bleaching the hair is a surefire way of ensuring success. However, what might not be known is that bleaching can only increase chances of success by a measly 40%. Furthermore, due to this percentage being so low, there is still a significant risk of failing the test.

Going Bald

It is only necessary to take a hair sample that measures 1.5 inches in length for a hair follicle drug test. It can also be used on arms or legs if you have such long hair. It is also dangerous to shave your head and can result in job loss due to suspicions.

Avoiding Cannabis for Some Time

When it comes to undergoing a drug test, many people assume they still have a chance if they simply stop using cannabis products in the days leading up to the evaluation. Unfortunately, this is not always true. In some cases, pot residue can remain on hair follicles for up to three months after their last usage. Consequently, we must remember that it may be essential to stay away from any cannabis substances for a period of four months prior to the drug test if we want to successfully pass!

Macujo Method: Best Way to Pass Hair Follicle Drug Test?

    • Sodium Metabisulfite
    • Sodium Laureth Sulfate

    In the course of the employment process, employers might conduct hair drug tests. It includes,

     Random Drug Testing

    Working in the drug-free environments employers strive to create can seem like extra security, however, the only way to ensure employees are abiding by the company’s code of conduct is to institute drug tests. Unbeknownst to many, employers have the right to random drug testing without any notice. The goal of these tests is not designed solely to detect prohibited substance use but also to provide inroads for helping educate and raise awareness around the dangers of using hard drugs between shifts or while at work.

     Pre-Employment Screening

    Employers can take the initiative to evaluate potential employees in the recruitment process, either through conducts or tests. This is a method to accurately understand whether a candidate is appropriate for a specific position. It allows them to monitor who is qualified for different positions and helps narrow down the decision in terms of hiring the most efficient candidate. Having that said, ensure you’re well prepared as tests may very well be included in your overall recruitment scheme and overseen before making any decisions about your role with the organization.

Products like Old Style Aloe Toxin Rid and Zydot Ultra Clean shampoos are often considered by those seeking to remove traces of substances from their hair and body.

    Reasonable Suspicion Testing

    As employers may suspect drug use in their ranks, they can opt to utilize reasonable suspicion testing. Furthermore, if further evidence is required to corroborate these suspicions, a hair drug test can be issued to the group being monitored. This proactive approach allows employers an effective way to verify behaviors and enforce standards whenever required. With valid evidence that employees defy the rules or act out of line accordingly, this type of preplanned response will provide companies with the long-term assurance of employee conduct and quality staff representation.

    Hair Drug Tests: Additional Occasions

    Probation and Parole

    Some organizations require a hair drug test for probationers and parolees. If the test shows that they have abstained from drugs, then they may be granted discharge from said organization. Completing a successful hair drug test is seen as a major accomplishment because it signifies that they are being rewarded with freedom after exhibiting exemplary behavior while under probation or parole. With the successful completion of this drug test, those undergoing probation or parole now have another chance to reform themselves within the guidelines of society.

Alternatively, when results are inconclusive or unremarkable, it allows the courts to move forward ruling on agreements that put the interest and welfare of a growing minor first.

     Athletic Competition

    Many sports companies are requesting hair drug tests in order to make sure that performance-enhancing drugs or dope medication have not been used before sporting events. This highlights just how important it is for athletes across the globe to remain clean and put their trust in skill, rather than using illegal substances to enhance performance. Taking a prohibited substance puts an athlete’s career, health, and reputation on the line, as well as tarnishes the stability and sanctity of the numerous sports leagues that can assist in the creation of future stars. Making the right decision when contemplating whether to use these kinds of drugs prompts a guaranteed outcome since doing so with integrity can bring success depending on passion, preparation, and natural ability.
