Hello Raji,

I was reading several websites information and there were a few that are Dermotologist Sepecialists.

How do you like that? One fellow said there are over 100 reasons that can cause hair loss. I'm sorry I didn't get the link, maybe later you can check into it? It just might be we are looking for "causes" in the wrong places!

You have already ruled out the blood tests, mercury toxicity, and a few others. Sorry, I'm in a bit of a hurry. Just want you to be informed that your dear wife may need to see a Dermotologist???
Try not to let the possible reasons be disturbing to you. I wouldn't give any thought to the hormonal estrogen one, unless you have her see her Gynecologist.
Take care, have a good weekend and hello to your wife.
