I'm a reformed nail biter, but this winter, I've had trouble with the nails splitting. It doesn't tear down to where it hurts/bleeds, but just a layer or two of nail peels back, especially my thumbs.
I've tried the nail strengthen nail polish (althought I admit it may be too old - can that happen?).
Any hints, ideas, suggestions?
