FREQUENTLY ASKED QUESTIONS
How soon after use can a drug be detected in hair?
It takes approximately 5-7 days from the time of drug use for the portion of the hair containing that drug to grow above the scalp.
How much hair is needed?
To complete a standard 90 day hair follicle test, a minimum of 1.5 inches is required (0.5 inches per month). The amount taken is usually cosmetically undetectable and can be compared to the thickness of a shoelace tip.
If I do not have sufficient head hair, can body hair be collected?
