Curious question: Hair grows at a rate of about 1/2 inch a month, and thc that is deposited in the hair will stay in the zone that represents use while it was forming. Remove the hair to below the that level and it would not be found on hair analysis. However, most do not assess hair to detect it, they use urine.This can clear in a week or so if use was minimal.
