Title: Causes cystic acne!!!
Review: Ok, so first of all, this product did make my hair grow slightly faster. However, I started breaking out when using it. Biotin causes cystic acne, which is a very painful, under the skin type of acne. I've never suffered from these kind of breakouts in my life. I took these pills for about 2 months and finally realized why my skin had become so horrible. Not worth it! Google it, you'll see that it is a common problem.
