Studies show that Hair drug tests are the fasted growing method of drug testing used by employers and marijuana is still number one on the list of drugs tested for, it also stays in your system the longest.

Top Questions and Answers:

How long does marijuana stay in your hair?

It takes approximately 5 days for marijuana to show up in your hair it can continue to be detectable through a hair drug test for several months. The presence of Marijuana and other drugs in your hair can be understood by this basic principle. Marijuana is ingested in your body and circulates through the blood stream into your blood, urine, saliva, and into the hair follicles via the bloodstream. The drug metabolites that are deposited into your hair follicle are entrapped in the hair shaft as it grows out from your hair follicle. The average growth rate for hair is approximately .5 inches per month. Drug testing labs test for toxin metabolites trapped in the shaft core. Historical drug use can be measured based on the length of your hair sample from your scalp line but a specific timeline of usage is not possible. They cannot tell the difference between THC metabolites introduced two weeks ago from metabolites introduced two days ago.

Example:

A 1.5″ length sample of hair is measured from the scalp line for most major hair drug tests. Based on the average head hear growth rate of .5″ inches per month, it can be determined that a positive test results would suggest that marijuana was consumed sometime within the past 3 months. Since most testing labs test 1.5 inches of hair the common known time frame for testing positive for marijuana is on average 90 days.

Can Toxins like Marijuana simply be washed out of your hair?

Drug metabolites stored in your hair are chemical and structurally stable in your hair shaft core, they can’t simply be washed, scrubbed or bleached out with conventional shampoos or cleaners. Only medical grade hair detoxification shampoos can remove the traces of drugs and the metabolites they produce from your hair.
