How to Pass a Hair Follicle Test

by jessie

Hair follicle drug tests are the most intense type of drug test. They have a timeframe for drug detection that is longer than any other test out there. If you have a hair follicle test coming up, you might be freaking out about passing it, and understandably so. But, luckily, we’ve figured out how to pass a hair follicle drug test that is safe for your hair.


What is a Hair Follicle Drug Test?


Hair follicle drug tests involve having strands of your hair cut at the root, which will then be studied to look for indicators of drug use. Hair follicles can show drug use because when you consume drugs, they are absorbed into your bloodstream, and your hair grows out of blood vessels in your head. Drugs can also stick to your hair through things like sweat and skin oils.


A hair follicle drug test is considered the most serious as drug consumption can be detected from as far back as ninety days. There is a certain limit for the amount of marijuana that can be present in your hair and still yield a negative result, but it is pretty low; one pg/mg in the initial screening, and only 0.1 pg/mg in the follow-up screening that is almost always conducted to verify results. 


How to Clean Your Hair for a Drug Test

You can expect to fail a hair follicle test if you’re even a semi-regular cannabis user. If you find yourself having to take a hair drug test, here are a few approaches many people seek in order to pass.


Home Remedies

It might seem logical to use some harsh chemicals and home products like bleach, detergent, baking soda, or apple cider vinegar on your hair in an attempt to cleanse your follicles of any evidence of drug use. Unfortunately, though, remedies like these are typically ineffective at best, and using something too strong could even go as far as to cause chemical burns on your skin. 


Using Detox Shampoos


Luckily, there are detox shampoos that are specifically designed to safely rid your hair of all indicators of drug use. You can order a hair follicle cleanser online and have it delivered to your door as soon as the next day, so you can pass your hair follicle drug test in two days from the time you place the order. It is effective and easy to use, just like washing your hair! Depending on your needs, you have the option of cleansers that will erase toxins permanently or a cleanser that will take effect in an hour and a half and last 24 hours. 


Hair Follicle Drug Test FAQ

Drug tests can be confusing, but we’re here to answer some of the most common questions about hair follicle tests.


How Much Hair Is Needed for a Hair Follicle Test?

Administrators of hair follicle tests will take 100-120 strands of hair that come to about an inch and a half each. Out of consideration, the administrator should cut from several different patches on your head to avoid any noticeable bald spots.


Can Body Hair or Eyebrows be Tested for Hair?

Yep! If you don’t have any hair on your head, the test administrator will find somewhere else to take your hair. 


What Can Cause a False Positive Hair Follicle Test?

Some prescription and over-the-counter drugs that you are well within your legal rights to take might show similar results to illegal drugs. Poppy seeds can also cause you to test positive for morphine, as poppy seeds contain opium. If you have an important hair test coming up, you may consider being extra careful about what you eat beforehand.


Can a Hair Follicle Test Detect One-Time Use?

If you only used drugs once very recently, they probably won’t show up in a hair follicle test as it takes a few days for the part of your hair that absorbed the drug to grow to the surface of your scalp. Though you may still be safe if you’ve only used drugs once in the past couple of months, you can’t bank on that since everyone’s bodies are different, and some may have a stronger reaction to drugs than others.


Does CBD Show Up on Hair Follicle Drug Tests?

CBD Isolate will not show up on your hair follicle drug test, but if there was any even trace amount of THC in the CBD that you consumed, you still run the risk of failing your test. 


Can You Wear a Wig to Pass a Hair Drug Test?

Sadly, no. The test administrator will cut the hair from the root, so they are bound to notice that the hair isn’t growing from the skin of your scalp.


How Do I Read Hair Follicle Test Results?

Hair follicle tests have a cutoff number, the lowest amount of any given drug (that is included in the test), measured in picograms per milligram, which will yield a positive result. This cutoff is different for each drug, and it will be a larger number for the initial test than for the confirmatory test. Many people incorrectly understand that the numbers shown in the results are a reference for the severity of use; the number simply indicates whether the result is positive or negative.
