This is a little late response. I didn't have this problem after my pregnancies, but I do remember my beautician telling me to continue taking prenatal vitamins for awhile afterwards, and then wean yourself off of them. This will help with hair loss according to her. (usually, you may notice when on prenatal vitamins your hair grew faster and your nails. But she would recommend prenatal vitamins to people who had hair loss problems w/o being pregnant, and supposedly worked)
