No, just waste of marijiana.
EVERYTHING stays on a hair test. Forever.
If you have chunks of marijuana in your hair, pick it out or comb it out. If you have the smell of marijuana in your hair, use shampoo. If your hair will be used to scientifically test for marijuana useage, and you have used marijuana, cut off your hair. Most likely if you're bald they'll ask for hair from another part of the body. If you're completely bald they might not give you a job. The only thing that can save you is to shave your head and get a wig that looks real and is made from human hair. But that would take a lot of work.
it will stay in there for about 2 years
