It's been two months since I cut my hair and started taking 1-2000mcg biotin daily. My hair has grown exactly one inch. This seems pretty normal, and I'm a little disheartened. And annoyed at the awkward hair ahead of me. Today I'm upping to 5000mcg. A lot of people online say you have to take that exaggerated dose to see any results. We'll see.
I decided to leave my second bottle of biotin unopened and bought some Nature's Bounty extra strength Hair, Skin and Nails vitamins instead. They have 5000mcg biotin, 50% daily recommendation of vitamin E, and a wealth of other vitamins, as well as added collagen, calcium, alpha lipoic acid (whatever that is,) and silica. I will be very disappointed if after a month my hair has not grown more than another half inch.
p.s. I forgot to mention, I did notice my eyelashes have gotten a little longer and my fingernails are growing a little faster, so I know the biotin's not been completely in vain.
