What is the Detection Period for Drugs in a Hair Test?

Analysis of hair provides a much longer detection window than other specimens. It takes 7-14 days for drug and alcohol bio-markers to be deposited into the hair root and emerge past the scalp.

Head hair can detect up to 90 days of drug abuse, and body hair can detect up to 180 days. Body hair does not grow as fast as head hair, therefore the biomarkers trapped will provide a longer window of detection.
