quitting weed thing won't work...so there's no point in even quitting, because they can test your hair up to i think a year after you've smoked and still test you positive. depending on what kind of detox shampoo it is, will work. some are fake, some don't have the best results and some work everytime... find the ones that give you a double or tripple money back garuntee.... they're almost always the ones that work everytime... because if it didn't they'd be losing more money then making it. if you get the detox shampoo make sure you read all the dirrections to it DAYS before you have to get your test, so you know when to use it (it only lasts for so long, doesn't just completely get rid of it, it hides it for so long, usually around 8 hours) and how to use it... if you don't follow the dirrections exactly you're going to be screwing yourself. if you can't find the right detox you're screwed either way, so if it's like for probation or something, and you can't get it... smoke up cuz there is no home remedy that's going to get rid of it. and you can't just shave all the hairs off your body, just imagine what you would have to do to get rid of all your hair.... going in wherever completely bald, no eyebrows, no eye lashes, no body hair would seem a bit suspicious....
