i don't know the "scientific answer" to this question, but i know from experience that if you wash your hair a lot then the weed wont be in your hair and it doesn't smell like it at all if you don't smoke weed that day. you really don't have anything to worry about with that, but i'd worry about the yellow fingers and teeth, that's a nasty one.
Years especially in hair
never
Depends on how long your hair is.
Yes - you can smoke as long as you accept a bald result. Say not to smoking.
how long ago ??
15 minutes
oil your hair daily before washing it......it makes hair long silky n manageable
you hair has to be at least 10 inches long in order for you to donate it
You would starve to death before your hair falls out.
The length of Micheal Jackson's hair before he died was 10 inches
12-24 Hours
To dream that you have long hair, indicates that you are thinking long and carefully before making some decision. You are concentrating on some plan or situation.
If you smoke .......... It wont be long before you croak:>(
