and I already shave most of my body 2-3 times a week because I'm an athlete (and naturally hairy which I don't like) so them taking samples from my body wouldnt matter.
I will speak specifically about marijuana and not other drugs because they are off limits to this site. THC quits depositing into the hair 7-10 days after your last use. So if you shave your head after this point, all the new hair growth will be clean. Average hair growth is 1\2 inch per month and most testers look for atleast 3\4 inch of hair to test. If the rest of your body is shaven and your head hair is not long enough, they will note this and take your fingernails instead. Your going to need 45 to 90 days of hair growth to avoid suspicion and pass this test.
