The second most used type of drug testing today is the hair follicle drug test or hair test (the hair strand is actually tested, not the follicle which is in your scalp). Your hair strand can be tested for any toxins ingested into your body.
The hair follicle under your skin produces the hair strand. The blood vessels that flow to the follicle will deposit toxins at its base, where they grow into the hair strand. While performing a hair follicle drug test, labs check the shaft of multiple strands of hair taken from your head or body for the presence of any drugs.
Your hair has the ability to retain a history of toxins you've ingested for months. A hair strand grows at an average rate of 1/2’’ per month. A hair strand that is only 3’’ is enough for testing labs to find out what you’ve been doing for the past 6 months!
Shaving your head is not a work around. If your scalp doesn't have at least an inch of hair, the lab would collect body hair samples (chest, underarm, or pubic area). If you have no hair on your body, then you'll be required to come back when the hair has re-grown or you'll have to submit to other types of testing.
Using the second hand smoke excuse doesn't work either. Second hand smoke from drugs like marijuana and cocaine can penetrate into your hair. But labs now employ advanced washing procedures prior to testing the hair. These washing procedures are delicate enough to remove external contamination that resides near the surface of the hair strand, but leaves the toxins that were deposited by your bloodstream into the follicle.
Masking Shampoos Can No Longer Help You Pass Hair Drug Tests
Many of the products available that claim to work in passing a hair drug test are called masking agents. They coat the hair with a residue in an attempt to throw of the test. These products actually worked a few years ago, prior to the advanced pre-washing techniques labs use today. Masking agent shampoos are effectively washed away by labs prior to even being tested for the presence of toxins. In other words, they don't work anymore, but they're still on the market, so be aware.
So How Do You Pass a Hair Drug Test?
Labs that conduct hair drug tests and companies that manufacture hair follicle drug testing products make bold statements because they gain something by doing so.
Whether or not you pass a hair follicle drug test will depend on a lot of factors no matter what product you use. Here are a few facts you need to know:
- Tests conducted in some labs are easier to pass than others
- Masking products no longer work. Labs now wash your hair thoroughly before testing. All masking substances are rinsed away while the hair is washed.
- To pass a hair follicle drug test the hair should be detoxified, not masked.
Toxins like drug metabolites make their way into the hair shafts and are deposited into new hair strands. The toxins are deposited in the cortex, which is the inner shaft of the hair strand. They bind to the keratin protein structures of the hair strand.
In order to detoxify the hair of these toxins any cleansing product will need to be able to penetrate the outer layer of the hair strand (cuticle), remove the bound toxin molecules for the hair keratin protein matrix, and then wash it away. All without destroying the hair structure.
Labs have the advantage of being able to destroy the hair strand structure and remove all the toxins for detection. A good detoxifying shampoo needs to do the same but without destroying the hair strand. Not an easy task, but the right detox shampoo formula can do an effective job in adequately lowering toxin levels and passing drug tests for THC, as well as other drug metabolites.
The New Precision Cleanse & Toxin Wash
Hair drug testing has been undergoing dramatic changes. Testing labs now have the ability to detect even traces of drug metabolites.That means that a one time use, one slip up, one mistake, can cost you dearly.
Technical developments in hair testing technology forced us to reformulate our hair detox product. With inputs from hair stylists, hair experts, and toxicologists, our research lab developed a product formulation that effectively detoxifies the hair strand. The products are called Precision Cleanse & Toxin Wash. Which product you use depends on your usage level.
There's a lot more information on the science of hair testing which would be beyond the scope of what you need to know. You can read more below about how Precision Cleanse & Toxin Wash products detoxify the hair for passing drug tests for THC and other substances.
