yeah you're fucked... first you'd have to be full detoxed, then shave all your hair and let new hair grow back to pass, without shampoo's that is... there are shampoo's to pass hair tests, but around here 40+ bucks for one test...

why is your SCHOOL hair testing you anyways? that just dosen't seem 'right' are you sure it's not a scare tactic? literally if i were in your situation, i'd look the 'leader' (principal, dean w/e is in charge of the school) to kiss my white ass and pick a hair with his teeth cuz that's the only way he's getting it....
