What is a hair drug test?

AHair Drying Testinvolves analyzing a small sample of a person's hair to confirm the presence of drugs or their metabolites.

Experts use hair drug tests to detect long-term drug use. Drugs and their metabolites can still be detected in the hair months after ingestion.

Hair drug tests are often more accurate than other drug tests, such as urine or saliva tests. You may notice prolonged drug use. However, drug tests for hair cannot detect recent use as accurately as other tests.

How does the hair drug test work?

After consuming a drug, your body converts it into what are called metabolites. As your system digests the drugs, it creates the metabolites.

Hair drug testing primarily determines the presence and concentration of a drug or its residues by analyzing a sample of hair. The test tells the scientist you've been on drugs for months. This is mainly due to the fact that drug residues can be detected in the hair follicles over a longer period of time.

It usually takes between 7 to 10 days for drug residue to get into your hair. Every time you ingest (smoke or ingest) a drug, it enters your bloodstream. After it reaches the bloodstream, it eventually spreads to other areas of your body, and your hair is no exception. The drugs enter your hair through the oil glands or follicles of your scalp.

The drug residues remain in your hair as it grows. As a result, your hair can trap these residues for several days, even up to three months. Also, the hairs on your head aren't the only ones these metabolites flow to. Hair in other areas of your body, such as B. in your armpit, these elements can also trap.

Note that hair samples taken from other parts of the body may contain evidence of drug use for up to 1 year. However, the ones taken from your head could keep the drug evidence for about 90 days.

What can a hair drug test detect? – Test process and main principle

A hair drug test detects the presence of drugs like marijuana in a person's body. These tests are more effective than urine and blood tests at detecting the long-term presence of drugs.

A hair follicle drug test can track drug use within the last 3 months. However, the exact time frame depends on the density and length of the person's hair.

Here aresome drugsA hair drug test can detect:

  • Amphetamines – including MDMA and methamphetamine
  • Marijuana containing THC (tetrahydrocannabinol).
  • Opioids – including heroin, morphine and codeine.
  • Cocaine
  • Phencyclidin

Other types of hair drug tests could also detect drugs like anabolic steroids and benzodiazepines. However, the specificity and sensitivity of these hair drug tests can vary.

Second, hair follicle drug testing can detect drugs consumed through smoking or ingestion, not those applied topically to hair or skin. Also, the hair drug test cannot detect the use of drugs less than a week old. It takes many days for drugs to digest and get into the hair.

Test Principle of the Hair Drying Testung

The hair drug testing principle is based on how drugs and their components integrate into the hair as it grows. When a person smokes or takes drugs, they flow into their bloodstream and gradually move to the hair follicles.

As hair grows, these substances become trapped in an area of ​​the hair shaft called keratin fibers.

To test for the presence of drugs in the hair, an expert sent the hair sample to a lab for analysis. This hair sample is then cut into smaller pieces and dissolved in a solvent. The purpose here is to extract every atom of drug present in the hair sample.

A common technique used in this test is called an immunoassay. The process involves using antibodies to detect the exact drug and its elements. Other techniques used are mass spectrometry and gas chromatography. These techniques separate hair components and identify the drugs contained within.

The test results come out after the lab analyzes the hair sample and identifies the drugs and their concentration levels.

The main principle of hair drug testing

The main principle of hair drug testing relates to the detection time of drugs and their components in hair follicles. Normally this period lasts 3 months (90 days).

Trying to pass a hair drug test in 24 hours can be difficult, but not impossible. With the right detox product, you could still pass the test. As you read on, you will discover the best detox shampoo to pass a hair follicle drug test.

Hair drug testing is one of the common testing programs in some workplaces and the criminal justice system. These are areas where the use of drugs is strictly prohibited. Many of these organizations use hair drug tests because of their reliability and accuracy.

However, some factors can affect the accuracy of a hair drug test. These include the amount of drug used, the type of drug being tested, the frequency of drug use, and the growth rate of the individual.

Some other forms of drug testing, such as urine and saliva, only detect the short-term presence of the drug substance. That is, if a person has used drugs in the past 3 weeks, such short-term tests may not detect the presence of the drugs.

What happens in the hair drug test?

Several actions take place during a hair drug test, each of which contributes to the success of the process.

Here's what you can expect during a hair follicle drug test.

  • The expert would take a sample of your hair and trim it from the back of your head. Usually near the scalp, about 1.5 inches long and as wide as a pencil.
  • The technician may require a hair sample from a different part of the body for those who are naturally bald.
  • After that, they send it to a lab to be washed and prepared for analysis.
  • Hair screening is the next step. The lab would use a technique known as an immunoassay. The purpose here is to determine the presence of drugs or their metabolites.
  • If the immunoassay test results are positive, the scientist will perform another test for confirmation. This is a more sensitive test called GC-MS (gas chromatography-mass spectrometry).
  • This last test confirms whether the previous one is correct or not. It also checks the concentration of the drug, if any.

Many experts consider hair drug testing to be the most accurate option. Aside from its accuracy, it also detects a wide spectrum of drug use. Some examples are cocaine, amphetamines, marijuana and many more.

How to Fail the Hair Follicle Drug Test?

Several substances can cause you to fail a hair follicle drug test, including your mouthwash. Here is a short list of materials to look out for before a hair follicle drug test.

  • Smoking or ingesting marijuana
  • Mohn
  • Weight loss pills
  • Mouthwash products
  • Antidepressants
  • CBD-Sol

You may be wondering how these substances affect hair follicle drug test detection times. Some components in these materials appear as drugs in a test.

For a better understanding, let us address these materials in detail.

Smoking and use of marijuana

Smoking or ingesting marijuana is one of the quickest ways to fail a hair follicle drug test due to its THC connection. THC doesn't just stay in your hair follicles; it also flows into your blood and urine and lasts for several days.

When preparing for a hair drug test, you might be looking for answers to the popular question, "How long does marijuana stay in your hair follicles?" It mostly depends on your dosing frequency. So the more exposure you have to marijuana, the lower your chances of passing a hair follicle drug test.


Every poppy seed naturally contains codeine and morphine. Your hair follicle test will fail if you take any of these seeds a few weeks before the test.

Weight loss pills

One of the most popular weight loss pills is Phentermine. The chemical composition of this drug is similar to that of amphetamines - an anti-ADHA drug.

Weight loss pills like phentermine could reverse a negative hair drug test if taken at least two weeks before.

Mouthwash products

Several breath cleansing products like mouthwash and vanilla extract products usually contain ethanol — a type of grain alcohol. Drug testing in today's world can detect traces of alcohol in the body, including hair follicles. Using such products could result in a failure on your next hair follicle drug test.


Sertraline or Zoloft is an example of an antidepressant. Most of these medications contain elements like benzodiazepines that can alter a negative hair test result. Benzodiazepines are mainly found in people who have overdosed on opioids.

Some tests may not distinguish benzodiazepines from sertraline. Therefore, it's possible to fail a hair drug test after taking some antidepressants a week or two before your test.


This is another product that can alter a negative hair drug test result. It is derived from a hemp plant similar to Cannabis sativa - the source of marijuana.

Some countries allow around 5% THC and some other edibles in this substance. Consuming these CBD products could leave the THC compound in your system and affect your hair drug test.

Misconceptions about hair drug test

Aside from the above substances, other ideas could cause you to fail a hair follicle drug test. Check them out below

bleach hair

Hair bleaching is a misconception many people have when it comes to passing a drug test for hair. You probably came across the idea on the internet. Note that the success rate is 40%. So the chances of failing the drug test are still high.

Avoid cannabis for a short time

Many believe that giving up cannabis products a few days before testing would save them. This is another misunderstanding.

As previously mentioned, cannabis residues remain in hair follicles for up to 90 days. So you may have to stay away from the substance for 120 days to be free of it. However, since you will only receive the test notification 3 months in advance, this option will not work.

Go bald

A hair follicle test requires a sample of at least 1.5 inches. So you have to give your boss a very good reason for taking your hair, especially the hair on your head.

This action is quite dangerous as it could cost you your job.
