I am goinh to be having a hairs strand test for marawana in a few weeks I was wondering if there is anything I could do to my hair or body to mask the metabolites in my hair and body so that the test could ocme negative for the drug please help could I dyer my hair blond would that help ?

The only way is to not have used . They can test more then hair from your head, they can use body hair as well. THC metabolites are deposited inside the hair, not on it, and changing your hair cosmetically won't get rid of them. You could try to shave everything off but some people will view your lack of hair, head and body, as an admission of guilt.
