As long as the drugs are in your system they're in your hair. I believe the only thing that hides that is some special kind of shampoo... Or if you waxed and got the whole follicle out... I mean what you did by shaving your chest hair was probably to get rid of the top layer... But there could of been traces of the drugs in the follicles still... Because technically... That's the root of same hair you cut... Which means you cut your hair for nothing... Good luck though!
