My previously very strong finger nails have started to split and peel and crack since some time in the fall (can't remember exactly).
Is it possibly that this is from wearing nail varnish for so long?
Or could there be another cause? My toe nails and hair are fine.
I've removed all nail varnish, and the back half of my nails is fine, but the front half, near the white end, is very thin and although I've buffed them, you can see where the top layer of the nail has peeled.
Any ideas?
