Customer Rating: Summary: I never thought it would actually work!! Comment: This nail hardener is AMAZING! I have never had long nails that were healthy and strong, except when I was pregnant... I tried this, and my nails are unbelievably long and strong! My husband really could not believe it. He always has joked about my short stubby nails, and never thought this product would work. He was pleasantly surprised when it did. Highly recommend!
