How does a hair drug test work?
When drug metabolites are in the blood, they’ll end up in the blood vessels, including those in the head, and get filtered through the hair. In basic terms, at least, this is how hair drug testing comes about. When you do drugs the drugs get in your blood and then filtered into the hair. Hair drug testing can go back months, showing the toxins a person may have used in a time-line fashion. Masking hair is not realistic as the sample is washed to remove left in products or external contamination such as secondhand smoke. A hair drug test involves cutting 50-80 strands of hair from the base typically at the crown of the head. A minimum length of 1 inch is necessary or body hair such as face chest or underarm hair can be used.

The hair follicle drug test is one of the hardest drug tests to pass because there is just no way of getting around or removing what is in your hair follicle. The best way to try and pass a hair drug test is to not do drugs but unfortunately with this type of drug test; certain things can be detected that you may have used months ago. The hair is a real giveaway for employers and probation officers who use this method of testing on how long you have been using drugs and whether or not you may have a problem. There is one flaw in the hair drug test though. It isn’t good at detecting very light marijuana use. It is very good at detecting cocaine and methamphetamine use though.
