I love, love, love OPI's Nail Envy. I have always had thin, peeling nails that just would not stay strong enough to grow. I've been using this for about a month, and for the very first time in my entire 32 years of living, I had to trim down my nails because they were too long... You read that right... TOO LONG. Oh my God! This product is a miracle worker in a bottle. BUY BUY BUY.
