Hi Chris

why do my fingernails have a. Horizontal lines and b. Sometimes indentations running across them?

Cheers

I learned from my parents that the white patches are generated by the excess salt consumption. I used to have these patches after Easter because our ham (traditional Easter meal) is very salty.

Yea, I agree with Physics_works that it's a dietary thing..

My parents told me that I had to drink more milk if I had these white patches, but that was probably a white lie to make me drink more milk ;)
