What Hair Follicle Drug Testing Detects
Hair follicle drug testing looks back 90 days—three full months of substance use history compared to the 1-5 day window of a urine test. As your hair grows from the scalp, drug metabolites become embedded in the hair shaft, creating a long-term record of substance use.
This is the standard test when extended detection history matters.

Why Hair Follicle Testing Is Different
A standard urine drug test catches recent use — typically 1 to 5 days back, depending on the substance. Hair follicle testing reaches further.
As hair grows, drug metabolites embed in the hair shaft, creating a 90-day record of substance use. Every hair sample collected at our Mesa lab is processed by a SAMHSA-certified reference laboratory under strict chain-of-custody protocols. Results are returned with documentation suitable for employer, legal, and program submissions.
Can you beat a hair test?
Detox shampoos, bleaching, and chemical dyes cannot trick a hair follicle test. The specialized laboratory analysis detects drug metabolites that are permanently locked within the hair shaft, not on the outer surface, and the lab performs a strict pre-analysis wash step to remove any external contaminants completely. Shaving your head or having short hair will not prevent a secure collection. Our certified lab collectors can easily use body hair from the arm, leg, or chest, which grows at a slower rate and holds an even longer chronological record of substance history.
Hair Follicle Drug Testing FAQ
How far back does a hair follicle drug test detect? A standard hair follicle drug test detects substance use over the past 90 days — about three months. The test analyzes drug metabolites embedded in the hair shaft as it grows from the scalp. This is significantly longer than a urine test, which typically catches use from the past 1 to 5 days.
How much hair is needed for a hair follicle drug test? We collect about 1.5 inches of hair, roughly the diameter of a pencil, from the crown of your head. The collection is quick — usually under 5 minutes — and the small sample is taken from an area that won't be visible. If you don't have enough head hair, body hair can also be used.
