Remedy for Thin Weak Finger Nails

My nails used to be hard too and I've found now that I've gotten older they have become more brittle. Not certain but I think it may come with age in my case.

I have always worn clear nail polish on my finger nails and that helps a lot. If your body is going through a lot of changes that could be the reason. I go through stages when my nails are weak and I have to cut them too. Just hang in there, they will get better.
