I have wondered if a study has been done into what conditions Alopecia sufferers develop in later life, as Alopecia may be an early indication of something going awry. And how many Alopecia sufferers take vitamin and mineral supplements? I have been taking zinc, chromium and Vit D for a few years. I have just discontinued these but it is too early to see if it improves things. I know accumulation of certain vitamins and minerals can be toxic.
