Top Questions and Answers:

How long does marijuana stay in your hair?

It takes approximately 5 days for marijuana to show up in your hair it can continue to be detectable through a hair follicle drug test for several months. The presence of Marijuana and other drugs in your hair can be understood by this basic principle. Marijuana is ingested in your body and circulates through the blood stream into your blood, urine, saliva, and into the hair follicles via the bloodstream. The drug metabolites that are deposited into your hair follicle are entrapped in the hair shaft as it grows out from your hair follicle. The average growth rate for hair is approximately .5 inches per month. Drug testing labs test for toxin metabolites trapped in the shaft core. Historical drug use can be measured based on the length of your hair sample from your scalp line but a specific timeline of usage is not possible. They cannot tell the difference between THC metabolites introduced two weeks ago from metabolites introduced two days ago.


A 1.5″ length sample of hair is measured from the scalp line for most major hair drug tests. Based on the average head hair growth rate of .5″ inches per month, it can be determined that a positive hair follicle drug test result would suggest that marijuana was consumed sometime within the past 3 months.


Can Toxins like Marijuana simply be washed out of your hair?

Drug metabolites stored in your hair are chemical and structurally stable in your hair shaft core, they can’t simply be washed, scrubbed or bleached out with conventional shampoos or cleaners. Only medical grade hair detoxification shampoos can remove the traces of drugs and the metabolites they produce from your hair.

How does Hair Detoxification Shampoo work?

Hair detoxification shampoo was originally designed as a medical contaminant removal product to eliminate toxins and toxin metabolites from prescription medications and medications administered during surgeries. It has an acidic base that destroys toxin metabolites but does not damage your hair. It is not toxin specific meaning that it eliminates metabolites from all toxin sources including marijuana.

How do you cleanse marijuana out of your hair and body?

Here are some options:

1. Naturally Detox your Blood, Urine and Hair in 90 Days

The body can be cleansed naturally of toxins like marijuana in roughly 30 days. Once your blood and urine is clean your hair shaft core will become clean of marijuana as well and after roughly 3 months of hair growth or 1.5 inches your new collectible hair samples will be clean.

2. Permanently Cleanse your Blood, Urine and Hair in 3-6 Days

A complete body cleanse will clean your blood urine and hair in about a week. In order to permanently cleanse your hair of toxins like marijuana you must first have no marijuana in your bloodstream. Remember, your bloodstream contains toxins that will continue to re-deposit drug metabolites into your hair that are detectable in hair drug tests so cleansing your body is the first step.

Step 1: Cleanse Blood, and Urine with permanent cleanse

This works by flushing out your system with a daily regiment of herbal supplements combined with a healthy detox dietary menu that permanently cleanses your blood and urine of any traces of toxins in your blood and urine in roughly 3-6 days depending on your toxin levels.

3. Cleanse your hair for 24-48 Hours with a Temporary Flush

If you don’t have time to cleanse your blood and urine before your test then a less desirable but effective option is a temporary removal of toxins in your hair through the use of Hair Detoxification shampoo only.

As we have explained cleansing only your hair core shaft when your system is not clean will only create temporary removal of toxins like marijuana and allows your hair to remain clean for approx. 24-48 hours before the toxins in your system are re-introduced into the hair shaft core causing the hair follicle to become dirty again.

Can they test body hair? What if I have short hair or am bald?

Hair follicle drug test samples can be collected from several head location and combined to get the required amount of hair sample for testing. The preferred location is to take it from the crown of the skull however if your head hair is too short, body hair can be tested instead. If body hair is used the time frame represented by the test is approximately one year due to the different growth pattern in hair below the neck. While body hair is generally acknowledged as representing a more distant time frame than head hair, the specific time period of drug usage cannot be identified due to the high variability of growth rates.
