If you have marijuana in your hair the simplest solution would be shower, if you're talking about drug testing keep reading...
If you haven't smoked recently it should be gone with 2-3 days. Constant users are detectable up to several weeks, longer than any other illegal substance is detectable.
Your best defense:
1) Shave your head. No hair, no marijuana!
2) Switch to harder drugs.
3) Wear a wig made of REAL HUMAN HAIR. Nothing fake or polyester, those tests sample the pH and they'll know something fishy is going on when they find out that they have a sample of your cat's/ferret's/barbie doll's hair.
Get a very good Lice removing treatment (shampoo, kits, etc). Make sure you thoroughly wash your hair with it. Depending on how long you have to remove the substance from your hair, you might want to consider buying a Toxin hair removal kit. For example, there is a store in my town called Yo Yo Dyne, and they sell all sorts of detox to remove marijuana from your system ASAP. Another option to consider is dying your hair. Bleaching definitely works but if you have dark hair you can go a shade darker and it will still work. There is a way around everything.
Shave your head. Or, to be safe, wax or shave your whole body as more and more hair screenings are done with other bodily hair.
THC(active chemical in marijauana) is stored in the hair folicle. Because THC love to store its self in fat cells. And is fat soluble. Happy toke'n
shave your head, hair tests cannot be faked, you can try soaking the strand in an alcohol solution, but it is not a fool proof method
a razor. It's like the rings on a tree once its in the follicle it's there for good.
You cannot get rid of marijuana in your hair. However, after about 45 days it gets removed by itself.
Time or a buzz cut
Remove hair
You can't unfortunately.
Drinking sperm has been clinically proven to remove THC from ones hair and urine.
if you're talking about a hair strand drug test, my understanding is that marijuana can be detected in the strands of your hair for about a year.
From smoking it.
No, exposure to the smoke of marijuana does not stay in the hair forever, but duration does depend on the frequency and severity of exposure and frequency of washing hair. What does happen though is, if a person smokes marijuana there are traces of it that reaches the follicles and grows into the hair. A hair sample can be taken from the person and tested and can prove that he/she smoked marijuana.
Time. And it builds up in the hair as well, and stays there till all that hair is grown out and cut off. If you don't have a scrip for medical marijuana , maybe you should quit.
If you did not smoke any marijuana, and you have since washed your hair, you will have no marijuana in or on any of the strains of hair on your head, and it will not show up on any drug tests.
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.

No, you must smoke it for it to be stuck in your hair.
