Hello,
I can relate to Ally. I was 43 when I had my last child and started losing hair after that. I noticed tons of it in my brush but didn't see a huge difference on my head. This year, at the age of 46, I didn't see a change until I started a very stressful job. It was so bad that I started having a lot of health problems, including extreme hair loss.
I saw my doctor and he sent me to a dermatologist. Fortunately, I no longer work there and was told it was merely stress. The dermatologist said I am not going bald and to try Biotin, like Ally suggested. I found a great product at GNC and have noticed a huge difference in only two weeks.
Hope this helps someone else.
