After years of of abuse by using acrylics and dips, my nails were a mess. Thin, peeling, breaking straight down I though I’d give this a try. It’s absolutely amazing! I even had one nail that stayed split down the middle that I had shut in the door of an SUV, at least 17 years ago, I never thought that nail would be able to grow out. It is perfect now! I’m hooked! Fantastic product! Thanks OPI!
