If your hair's long enough they can detect years back, but drug testing places can only test the length of hair that gives them the last 90 days
Who Dat Reviewed by Who Dat on . hair test- detox shampoo ok i've read that detox shampoos work but everyone on this site seems to think that they're total bullshit. Has anyone here tried the shampoo? or is it really just a bunch of bull? if so, that sucks because that means i cant smoke for six months. Rating: 5
