Actually, no hair can constitute a refusal of test and they have several courses of action such as taking fingernail samples.
FakeBoobsRule Reviewed by FakeBoobsRule on . Hair Test Tomorrow Got a hair test at school tomorrow.. just bought "AllClear Hair Purifying & Cleansing System" shampoo & conditioner. Anyone know about this brand? I also heard putting vinegar in your hair helps too, is this true? I've also heard that the testing companies nowadays can detect the detox shampoo. Is this true?
