I have a nail that’s completely messed up right now (long story) and I recently began to worry that it was just going to break in half. I happened to have an old bottle of Sally Hansen Hard as Nails and had been putting that on the nail, which seemed to help. But I left the bottle at work over the weekend, only to have the polish start peeling off on Saturday. Fearful that the nail would snap, I picked up a bottle of Sally Hansen Diamond Strength Instant Hardener. I love this stuff! My nail feels as strong as my other ones now. I think every household should have it for any kind of broken nail. I know we’ll never be without it.
Note: I got my bottle at Target for $4.89 plus tax.
