This page will supply
you with hair follicle drug test information. First off, many refer to a hair test as a hair follicle drug test. Know that the hair follicle is not actually tested, but itís the hair strand thatís tested. The hair follicle is part of your scalp
in which your hair grows out from. The hair follicle can not be removed without a surgical procedure (the hair follicle is removed and transplanted in hair restoration surgery). So while this page gives hair follicle drug test information, as itís so commonly called, now you know the hair strand is the only thing thatís analyzed in a hair drug test.
Many of the labs that give hair tests have accurate hair follicle drug test information on their websites about how hair drug tests work. But we will show you this information just for the sake of being complete.
Just know that any drug metabolites (what your body converts the ingested drugs into), are carried throughout your blood vessels and deposited at the Papilla (which generates the hair strand).
As the papilla generates the hair strand, the drug metabolites deposited at the papilla are grown into the cortex, or middle region of the hair.
When discussing hair follicle drug test information, itís important to understand more about whatís going on in the cortex, since this is a key component of hair testing.
The cortex (center of the hair strand) is densely packed with keratin proteins and pigments. And as the drug metabolites are grown into the hair strand, they are now in the cortex as well. This why you can not just shampoo your hair and pass a hair follicle drug test.
More Hair Follicle Drug Test Information
Without getting too technical, a hair drug test is done by clipping (not plucking in most cases) the hair about 1/8Ē from the scalp, taking about 1.5Ē of hair (most labs will work with 1Ē of hair since many people wear their hair short).
The hair is then washed thoroughly (the reason why masking products no longer work), and then dissolved in a solvent. The drug metabolites become separated out of the hair and then can be read and detected.
Hair Testing Cut Off Levels and Detectability of Different Types of Drugs
It used to be at one time that
hair drug testing would catch only the drug addict or abuser of drugs, as we believe it should
do. The cut of levels (the level that they can first detect drugs in your hair) were at a point where it would only detect the person who abused drugs and could be considered a liability as an employee.
In the present day, as technology has advanced, cut off levels are now near zero, or no tolerance levels. This means that even the casual user can fail a hair drug test. This was our case and the reason why we decided to create this site on hair follicle drug test information. We feel that this invalidates the whole point of hair testing in the first place, which was originally intended to keep drug addicts from being hired.
One more important piece of hair follicle drug testing information is that certain substances are more detectable in a hair drug test than others. While casual use of marijuana may be detected, one time use of cocaine, methamphetamine, or opiates can definitely be detected.
This page of hair follicle drug test information was intended to give you a background in which to form a basis of understanding on how to
pass a hair drug test. The next section and one after that deals with hair follicle drug test information pertaining to how to pass a hair drug test and then we list, review, and
recommend methods on how to beat a hair drug test.
