I take it and i love it!

My hair shrinks a lot, but now biotin is compensing the shrinking making my hair grow more and more.

I take from 5000 to 12.500mcg daly, my hair is a lot stronger than before.

I love it so much that i have bought biotin for 3 years!

Glad to hear that. I've been taking biotin too (from Hercules Vitamins) and I'm really satisfied with the results (and yeah, biotin keeps my nails stronger too).
