In reply to Mr. Lee:
I have similar nail problems but caused by different use - I am basically really heavy but can crimp harder than I weight which causes either the nails to pull free like you say, delaminate where the nail layers come free or the force I put through my fingers forces the finger flesh up so hard that the nail slices into the finger around the edges.
Keep the nails trimmed flat to the tip, stops snagging and the weird pressure splits/cuts.
Snip off hard side cuticles and moisturise.
If you get nail problems, clean and apply Savlon antiseptic cream, wrap in a fresh plaster or use fresh finger tape. I leave this on overnight then allow the skin to dry out and harden back up after any initial healing has closed up any holes or cuts.
They are a bitch, I have thick nail varnish and taping which don't work, only recently when I started taking zinc and magnesium supplements for other things I notice my nails and skin recovered quicker
