Works

I think it works! Ive been using this for about a year now. I take 2 daily. A hair vitamin helps when combined with other good practices.

I think this works.

Wife takes this daily for her hair and nails. Is it working? Well, she still has hair and fingernails, so maybe.

Great buy!

This product has more mg of the central ingredients vs other branded products. I like that it is only 1 pill per day vs the 2-4 pills other brands recommend. I'm anxious to see if this helps with my hair.

Vitamins

Was taking 5000 mcg of biotin since having Covid. Wanted something stronger that I only have to take one pill instead of two. Takes time. But I’m hoping it helps my hair los.
