I was given this product in exchange for my honest review. I've only used this product for a couple of weeks. It's hard to tell from my before pictures, but my nails were very weak and peeling. Once I started ePhD, I trimmed them back and used the product every day. I can definitely see the improvement in my nails. They feel stronger, and I have no peeling at all. I will definitely keep using this product and expect to see even more improvement as they grow!
