I'm wondering if anyone else has examined the hairs that fall out. Mine have a very small black area -- just a dot really- at the very tip of the bulb end (not sure of the technical term, but the end of the hair that attaches to the scalp). On the part of the hair looks like a q-tip, at the very end of mine it is black, where the rest of the blub area is whiteish-clear. Anyone else?
