    I keep my hair about 1/2" long. Will the person performing the test gunna want to take body hair instead? How long does the hair need to be?

    Hair should be 1.5 inches in length because head hair grows at *about* 0.5 inches per month, so 1.5 inches of hair *should* reflect 90 days worth of drug use/abuse history.

    If your hair is too short, they will want to take it from elsewhere on your body. Chest, underarms, etc.
