I had hair loss 3 years after my hysterectomy. I still am not 100% on what caused it but this is what I came up with. I was on estrogen and had decided I didn't need it (it had caused weight gain and I couldn't seem to get the pounds off.) two months after I quit taking the estrogen my hair was falling out. I had 3 patches that were very noticable. I ended up having to buy a hair piece as I was completely bald from my forehead to the crown of my head. I was devestated!!! I had lost my weight finally - but I had lost my hair too! After hitting a deadend with my family physician and gynocologist I went to a dermatologist. She gave me a cream that I put on my scalp 2x/day. Within two weeks my hair was coming in. Now I also went back on a "natural" hormone replacement - and grateful I did! I can sleep at nights again and mood swings have vanished! I haven't been able to locate the cream to give you a name but if you are still having problems, reply back and I will call and find out what it was.
