Did your mother ever say that you caused your mom to lose her hair? The good news is other than maybe having her pull her hair out once in awhile, your mom did not lose any hair because of your behavior. As women age, they tend to have Androgenetic Alopecia, which causes hair to thin and ultimately fall out. The main cause for Androgenetic Alopeciafrom age is due to the change in hormones. For you younger women, not only can hair loss come from menopause, but it can also be caused from birth control.
