I am happy to report that it works! My nails grew faster, were stronger, and just seemed healthier. I also really liked that when used as a base coat, it didn't negatively affect the life of my manicure. The formula was fantastic in that it wasn't too thick and dried incredibly quickly. It was very easy to apply and didn't smell intense. I found my bottle at my local Marshall's on sale, but I would absolutely buy this at full price. I haven't tried any of the more specialty versions. Have any of you tried the specific treatment products from OPI? If so, please share your experience in the comments!
