If it's tested like weed, and I can only assume that it is (basic principle is searching traces of the smoke in the person's hair) then however long it's been since you have had a haircut plus however long the hair before that was growing ( It's hard to explain this part. Hopefully somebody will be able to better articulate this)I've heard that they make shampoos for hair tests with weed but your best bet is to cut it all off. It's these second surest way not to have traces in your hair. The first of course is to not do it at all but that's your decision. Hope this helps!
