I have an interesting question: I have been using the comb for a little more than a month now -- I do shave my head every 2 days with a razor, so it's not easy to tell whether it's working or not. However, I get the feeling that I may be shedding some hair: obviously I don't see hair falling off in the shower, but I can see my "stubble" (the little bit of growth that appears after a few days of not shaving) getting thinner. Is this even possible? In other words, can you see the results of shedding even when you shave your head? Or am I just imagining things?
