How Does Weed End up in Hair?

Usually, it requires one small sample, around half an inch in length to determine the presence of THC in the body, which is the main intoxicating compound of the marijuana plant. However, there are two ways how the pot can end up in hair.

One is through an oily excretion on the smoker’s skin, while the other is more of a second-hand contact when follicle gets exposed to the smoke.

But, let’s explain this a bit further!

In the first case scenario, the person’s skin oils move the THC from the bloodstream to the hair. This is the most reliable detection of previous marijuana use. You must be wondering why?

Well, THC can only be absorbed through the fat, not water. On the other hand, your metabolic rate plays a crucial role in how much time does thc stay in your hair. For instance, individuals who have more body fat will keep THC longer than people will less body fat.

Additionally, the frequency can also affect the results and increase the chances of discovering marijuana in the body. Based on some study in 2017, daily consumers ended up with positive results. Nearly half of those who toked weekly were tested positive, while people who haven’t smoked within the last three months came up with negative tests.

How Long Does Marijuana Stay in Your Hair?

Hair follicle test is often used in corporate cyclers and can track the marijuana in your body up to 90 days. Therefore, this screening is designed to identify long-term users.

So, if you are asking how long does marijuana stay in the hair, the answer would be pretty much around three months. However, the only reason for this time gap is because that’s how long these tests go back in time.

On the other hand, there are certain factors which affect how much time does thc stay in hair:

  • The frequency of use – someone who is a heavy user already has a buildup THC in his system, which means it takes longer for a pot to leave the body.
  • The concentration level – if the weed has a higher percentage of THC, the chemicals in body will last longer.
  • The method of application – how you use pot will have a significant impact on time. For example, if you smoke cannabis, then it will leave your body within a couple of days. On the other hand, if you ingest it, then chemicals take more time to break down.
  • Weight – we already mention that THC needs fat to absorb, for that reason, people who are obese, or overweight might need some time to get rid of marijuana from their body. However, physically active individuals who exercise regularly, eat well, and have a lean body mass, will not have this issue.

Marijuana Detection Time Based on Usage

To determine how long does weed stay in your hair, you must pay attention to the frequency of use.

Take a look at our chart for more detailed analysis!

  • One time only – can be traced back between five to eight days
  • Two to four times per week – can be traced back between 23 to 35 days
  • Five to six times per week – can be traced back between 33 to 48 days
  • Two to four times per month – can be traced back between 11 to 18 days
  • Everyday use – can be traced back between 49 to 63 days

Not All Hair Follicle Tests Are The Same

Drug hair tests mostly depend on the purpose and on the lab that is performing the screening. For example, a person, or the company can request this procedure and choose the facility where the samples will be sent. Usually, the most common substances traced are cocaine, amphetamine, weed, and others.

You should keep in mind that standard follicle tests can trace substance in your body back in 90 days. But, in some cases, more advanced and equipped labs can go back up to a year to check whether you used drugs.

It takes three days to get the results after you submitted the samples. If you don’t collect the results yourself, the company that requested the screening will get it on your behalf. In that case, they will also receive good or bad news.

On the other hand, if you decide to go bald, then the lab technician will take samples from your chest, arms, or legs. Everyone considers follicle tests to be more accurate than the urine ones because they have only one procedure and are performed in the same way.

Detection of THC During The Test

Once the samples are collected, the technicians wash the follicle to remove any contaminants. They were then drenched into a solution that’s meant to break down the hair to its components, to discover compounds that are rooted in the hair shaft.

In most case, labs use specific antibodies to bind the targeted molecules; in this case, THC.

When the test comes back positive, another sample is required, just to confirm the previous screening. However, secondary checkup involves a more advanced procedure where lab technicians try to eliminate all errors.

Therefore, this procedure is called mass spectrometry, and it can scan the follicle and detect molecular signature. Once they find the final concentration of the chemical, the technicians can provide the final verdict. To confirm the levels of cannabis in your body, they use 0.1 pictograms per milligram of hair.

If your results go above that, then it supports the fact that you used weed in the last three months.

How Accurate Are The Hair Follicle Tests?

This screening is more accurate than the urine one; however, it can’t pinpoint the exact date the person used the pot. Even though the samples go through a two-step procedure, they aren’t 100% accurate.

There are a couple of factors which can affect the results:

  • The structure of the weed
  • The amount and how much the person has consumed
  • How much the individual sweats
  • The quantity of melanin, certain drugs tend to bind more to this component
  • Bleaching

The use of regular shampoos doesn’t have the power to affect the results or determine how long does thc stay in the hair.

On the other hand, there have a couple of alarming trials which indicate that this screening shouldn’t be taken for granted. For example, 2017 case study compared the results of 3643 self-reported drug users. Everyone we surprised with the results when they produced less false positives than more false negatives.

Considering the percentage, scientists were able to conclude that these tests do not offer reliable information. So if you are wondering how accurate are the results, they aren’t, and you still have a chance to getting out of it.


How To Get Rid of THC From Your Hair?

It is quite challenging to mask the effects of drugs in your hair. The regular shampoo isn’t potent enough to wash down the THC since it’s deeply rooted in the follicle. It doesn’t matter how many hours you spend washing down your hair; this compound is stuck inside and can’t be stripped away.

Some people often try a different approach by using lemon juice or vinegar, but you are only wasting your time. The acidic substances, regardless of their strength, won’t have any effect on this compound, but only make your hair shinier.

On the other hand, you can try bleach, and this can be effective, but you will end up damaging your hair. What you need at this point is a detox shampoo, it has an acidic base, but it doesn’t ruin your follicle. Among the most popular ones is the Aloe Rid shampoo (but the older version).

Additionally, you can try Macujo and Jerry J method. They are known for their efficiency and can help you come up with the negative results. Another question that seems to be bugging pot users is how long does it take to get clean?

Old Style Aloe Toxin Rid Shampoo

For more advanced users, you will have to repeat this procedure for a couple of times. On the other hand, light smokers will only need one dose of shampoo.

Another interesting fact to consider if you are thinking about how long does weed last and how to wash it away. For example, if you smoke cigarettes every day, then it will be hard for lab technicians to detect the traces of THC in your body. It has similar components of tobacco smoke, and it’s more challenging to identify.


Overall, even if you are a heavy marijuana user, there are a couple of ways which can help you beat the standard tests. Some of the methods we reviewed in this article show quite promising results, even though they can be a bit pricey.
