I have been taking aromasin for almost a year now...my hair had grown back pretty good ..although gray. Now it seems I am losing it and is very noticeable ..maybe because I had colored it brown and you notice the scalp more. Also, still have neuropathy in hands and can tire easily. Have others noticed these side effects ..especially the thinning hair and what did you switch to? I had previously tried arimidex right when I finished chemo and had awful side effects from that.
