Hair Testing is something that is very simple.  Evidence of drug use will begin to appear in the hair follicle 30 days after use.  The window of use that is typically tested is from 30 days prior to the date of testing back 120 days.  

If you are facing a hair test and are a regular user, the truth is there is nothing that can remove toxins from the hair and nothing that can be done to insure a negative result.

There are far too many companies out there, deceiving others when it comes to hair testing.  They take advantage of those in need of honest advice by giving them false hope that evidence of drug use is actually being removed from their hair, when that is absolutely impossible.

Shampoos work on the same premise, they leave a residue that improves the odds of a test coming back negative.  Such shampoos range from $25 up into the hundreds, but all do the same thing.  If you are a very light user, then getting the shampoo is well worth the money, it would be best to call to talk with someone to make sure.
