This seems a good place to start

Bare naked nails warning! I'm kicking this blog off with a post about my adventures in nail care. I've been making a serious effort to condition and grow my thin, peeling, dry crappy nails.

So far, this has involved a LOT of intensive moiturising of both the nail plate and the cuticles.
I also make sure I keep a protective layer of polish (even if it's just one coat of clear treatment) on my nails at all times and wear gloves when I wash up. Soaking nails in water and detergent causes peeling.

Before - flaky peeling nails 27/4/15

After - much less peeling 20/05/15
