Got this product in the hopes of strengthening my nails, but in fact it did the exact opposite. After just 1 use, my nails started peeling, chipping and breaking. I used the same nail polish as I always did before using Sally Hanses nail strengthener, and it was fine before - so I know it is not the strengthener's fault. My sister also told me she was taking a break from manicures as her nails were peeling - and she was using this product. Do not recommend this at all
