I admit it. I bite my nails. It's a bad bad habit, I know. In the past, to prevent me from destroying my nails I would run over to the nail salon for fakes, hoping that this would solve my problem. It worked but it got so damn expensive that I had to come up with a different solution. That's when I met OPI's Nail Envy and my own Willpower (yes, capitalized). This natural nail strengthener has turned my soft, brittle nails into harder, stronger and longer nails. This polish contains wheat protein and calcium which helps prevent breaking, splitting and peeling. Now that my nails no longer look like a war zone I am less likely to chew them. This polish is expensive at approximately $28.00 a pop but it's so worth it. I purchased mine at the nail salon but I believe you can get this at Trade Secrets and/or any other beauty supply store. It comes complete with directions and you only have to apply it every other day. For more information click here.
