a hair follicle test ?? are u goin into the CIA or somethin... one of my best friends dads used too work at a clinic where he would give hair folicle test and i remember one day he sounded hella sketchy and like worried when his son asked him about the shampoos that can suppossedly rid your hair follicles of any traces of drugz, cause he said it throws them off occasionally but theres only 3 or 4 brands that actually work .....some of the others will make your hair fall out !!! but if you really wanna pass I suggest you use that whole fuckin bottle of shampoo !!!!!!! it dosent sound you did too much though but it really depends on how recent in the 90 days u did that stuff. good luck
