I don't have any advice to give. I'm just glad to know I don't suffer alone.
I'm Black and I have dark thick hair for sideburns and beard that are really bad. I pluck the beard and shave the sideburns when they get to the point where I cant't stand them, which is usually two weeks past when I should probably have shaved them. Sometimes I just get so tired of having to do it that I just let it go.
The mustache (sp?) isn't so bad; there are only two or three coarse hairs there that I worry about.
I also have hair on my chest. It started out as a couple of stray fine hairs. Then I made the mistake of shaving those off. More came back and they were darker but not coarse. Now I just leave those alone

.
Can't afford laser yet but will probably give that a shot when the budget allows.
My endo wrote me a rx for Vaniqa (sp?). I got it but haven't tried it yet. Maybe I'll start tomorrow since I just plucked on Sunday and the chin is clear.
