Biotin helps with skin and nails as well as hair. Seems to help keep my nails healthy and my skin as well.

Hair and nail supplement.

This product has a lot of biotin in it. I had looked at several brands to compare. My nails are growing fast maybe my hair will too!

Need a “boost”

I take this because due to both menopause, as well as salon damage on my hair, I need an extra “boost”. When I take biotin in conjunction with collagen, peptide powder in my coffee, you feel as though it helps my hair to grow healthier
