Ask to have your ferritin (iron) levels checked along. I was losing hair, and it really bothered me. I'm also female. When I went to my Dr., she checked my thyroid but also said it could be to low iron. My thyroid came back normal, but my ferritin came back extremely low.
So now I'm on a supplement of Ferrous Gluconate, and my hair is growing back in.
Good luck.
