3- its okay i guess. I didnt notice any change in my hair. Been taking it for almost two months. Hair still keeps falling. Still breakable. I think my diet just isnt good enough. Anyone with a not so balanced diet will not achieve good hair.

Biotin is really helpful for your hair skin and nails, works really well over time

I've been taking biotin for a couple months now because I wanted to test the hair growth. I can't tell the difference in my hair but my nails are growing like crazy
