It may seem an odd question, but I'm wondering about other peoples nails and hair here.

My nails are very thin, brittle, and moreyellowy transparent than they are white. Can this be due to mercury or just some other dietary deficiency?

I used to have really curly, wavy, thick hair, but a couple of years after the fillings, my hair started to lose its curl, became dry and brittle. For a while I thought I was losing my hair.
