jeannine as Jon suggests, it's a possibility, but hair loss could be linked to all sorts of issues. Certainly, genetics play a huge role as does stress and many other issues. In my case, I started turning bald about age 40, ten years before I started taking statins. I wear my bald pate proudly, and I must tell you, a low cholesterol level trumps a head of hair!
Hair loss from Lipitor happens in patients in .1% to 1% of users. You should mention it to his doctor as there are other statins that are not as likely to have this side effect.
