I have a horrible time with my nails, they grow but always break or chip. So I have been using Sally Hansen's Hard as Nails in clear to strengthen my nails and keep them from breaking. Hard as Nails comes in a few shades, but I find the clear works best on my nails.
I have always trusted Sally Hansen when it comes to nail products. This polish does a great job of making my nails look buffed and neat, plus I do find that my nails seem to hold up better when I have Hard as Nails on them. I'm not saying they don't still break, but they don't seem to break as much or as badly. And with the clear color, I don't have to worry about my nails looking messy should the polish start to chip. That is one of the reasons I prefer the clear.
Sally Hansen has a lot of products for the nails, and I'm sure that no matter what condition your nails are in, Sally Hansen would most likely carry a product that would help. I have the Hard as Nails clear polish on right now as I type this review, and my nails look really nice. I will definitely be using this product in the future.
