Unfortunately there doesn't seem to be that many before and after pictures from actual patients around the forums dude...Opinions vary greatly on whether they are of any real value to hair loss sufferers or simply a snake oil device.....if you decide to go down that route please could you let us know how you get on.
I do know of a guy who I used to speak with who has a hairmax comb and he swears it has helped stop his hair from falling out but he also says he hasn't re grown any either*nl. This could be coincidence though so who knows dude.
