Yeah, I lost a lot of hair after I had my daughter and I was thinking along the same lines as you. It's all hormonal. I just hate it b/c I went several months with bald spots until my hair grew back last time. I thought I would never have to deal with that again until I had another baby or I was getting older...guess again! Thanks for your input. It's good to know that someone else is thinking the same way that I am.
