It's Hair Loss Support At Its Best
i'm pretty sure that the white fuzz is a good sign that it could turn to dark "normal" hair at some point if you take care of it. I say if you have white fuzz, do everything you can to help stimulate it without aggravating it. I'm wondering if you could dye it too, cause i also have white fuzz. I think if its a more natural dye without ammonia it might be okay.
My white growth has been here over 12 years, so I am not hoping for regrowth at this point, and did have a shop (also tried myself) dying the sideburns and hairline hair to match my red or brunette wigs. Now, I just gave up and bought a blond wig...no more dying. However, if I go back to a dark wig, I may get one that will cover sideburns and hairline totally to avoid any more dying. I really don't care about hair growth any more...too old, too resigned!
Do not use dyes that may cause birth defects if you are thinking of ever getting pregnant or may get pregnant again.
