I noticed some extra grey hairs popping up recently, and some thinning around my temples. While I don’t think these supplements helped my hair grow or fill in over the 30 days I took them, I do think my nails are looking a lot better! My nails were getting flaky and brittle, and they are looking so much healthier now. I’m sure a hair supplement would also benefit your nails. So that was a nice little side perk. I am sure over the course of a longer trial I would see noticeable hair benefits and more nail benefits. I would recommend this product and keep using it myself!
