grow back hair

Hello!!

I''m a black male, and I’ve been suffering from dandruffs since I was a little kid. Now I think I found the cured for it; however my hair won''t grow back at certain part of my head (especially the borders).

So I was wondering if any of you would know a good product or some other ways to get my hair to grown back?

Thank you for your help

you can try taking biotin and msm to thicken up your hair. also nioxin hair treatments. eat more protein cuz hair is mostly protein.

avoid chemical relaxers/texturizers and super tight braids.
