I'm going to be applying for a new job in a month that requires a hair drug test. I smoke weed on occasion and need to pass this test. Most jobs typically test by urine, which I always quit well in advance to get clean for. Does anyone know anything about these tests? I'm wondering exactly how deep in the hair it actually is. I've shaved my head for years, so that is no problem, and I have no problem shaving everything else off. But will shaving my body completely and letting the hair grow back so it doesn't look suspicious work? Or will it still show up when it grows back? I hope my recreational activities don't offend anyone, if so I apologize in advance.
