I agree with HH, Soda, something to try after checking with a doctor. Another thing, I saw in the Living Right thread that you've been losing weight. Make sure you're still getting enough protein. Makes a big difference in hair and nails!

Anyway, our hormones can change, but don't assume that whatever shampoos and conditioners you've been using have stayed the same. They often change things in order to manufacture things more cheaply and don't tell anyone. Or so I've read.
