burn your scalp off
If there isn't enough hair on your head, they take it from somewhere else. Pits, legs, scrotum, wherever.
Secondly, pot stays in your hair forever. It's like the rings on a tree, it leaves residue in the hair thats growing during the time you're on drugs. To pass the test, you need about two months off so you can have about an inch and a half of clean hair at the bottom for them to take.
