10,000 mcg Biotin. My hair is now at hip length with this! (I switched to this 4 months after stopping Viviscal). It took me a total of 19 months to get from a shoulder blade length cut to the top of my hip bones. When it reaches an inch or two past tailbone length, I will start trimming it more regularly to maintain it at tailbone.
So sad, cause I chose this for myself but I experienced major hair loss, anger/rage episodes and I only had it in for 3-4 months. Since removal I've had anxiety, cyclic breast pain and pms issues including hormonal imbalance. it's been almost 3 years.
