I originally took the supplements because I noticed my hair was thinning a bit and my nails were constantly breaking. After taking two capsules a day as directed, Ive started to notice that my hair feels fuller and looks shinier. It used to shed a lot when brushing, but that has decreased. My nails, which were soft and prone to splitting, are now much stronger and smoother. The capsules are easy to swallow, and I havent experienced any stomach issues, which I sometimes do with other supplements. I also like that this product contains not just biotin, but also collagen, keratin, folic acid, and a blend of vitamins and minerals. It feels like an all-in-one formula that supports my beauty routine from the inside out.
