Dose of Biotin
Be careful. Biotin will not stop your hair from falling out, it will only help with the new growth. When I say new growth I mean everywhere. I stopped taking biotin when the hair I didn't know I had on my face started to show up. Not pretty. Both my doctor and surgeon said there was no proof that biotin helped stop hair from falling out. 7 months out and I can see some new growth!!!!
