My hair is very short – I do not cut it, I buzz it. Can I buzz my entire head, not just the back as you recommend, but the front, also? Will this give you the amount of hair needed for the hair test?
This will provide a perfect sample for men and women with short hair (buzzed, I mean). Gather up all the clippings from a full buzz cut. This provides the most recent growth from all over your head, it secures that you can satisfy the 1-tablespoon needed by our lab, and it also secures a recent health reading for you.
Your situation is actually ideal. Buzz away!
