Biotin and Eyelashes

I have been using Biotin daily since my RNY almost 18 months ago. Although I have had significant hair loss, I know it is growing back. Another plus from taking the Biotin is that my eyelashes have been growing too. I used to have short, thinning eyelashes. Now, I have thicker, longer eyelashes. I love it! I know that taking too much Biotin can cause unwanted permanent facial hair growth, but 10,000 mcgs a day seems to be right for me..and I haven't started growing a beard...lol
