Hair loss in women can be caused by temporary factors such as pregnancy, autoimmune conditions, significant psychological stress, hormonal changes, and deficiencies in iron, vitamin D, and vitamin B12.

“so any woman listening to this who's been pregnant will absolutely understand that your hair tends to get thicker during the pregnancy and then post pregnancy your hair tends to thin and it thins usually more than the gain of thickness that you had during the pregnancy so again do we include that in hair loss for women yes or no that would sort of determine a little bit where these numbers shake out but I think for the purpose of this discussion we want to talk about forms of hair loss that are not related to some of the other more treatable causes so what might those be well autoimmune conditions along with significant psychological stress and hormonal changes again we talked about those in pregnancy and menopause but also deficiencies in certain vitamins and minerals and the most notable examples here are iron vitamin D and b12”
