Mine has been coming out too, lately -- not sure if it's med-related this time. Several years ago when I was on Depakote, it started coming out in clumps, but that's a known side effect of that med. All I'm on now is Seroquel and Effexor and the occasional Ativan, and I don't think hair loss is related to any of them, but haven't checked for sure.

My last pdoc (the one who actually took the time to talk to me, instead of getting me in and out of his office in under 5 minutes) said that sometimes hair loss can be a result of not having enough of some mineral in your diet. I can't remember the name of it offhand -- selenium, maybe? And another one that started with a Z. I can't take multivitamins anymore (interferes with a med I can't ever go off of, ever), but maybe it will work for somebody else.
