I am having excessive hair loss post partum. Before pregnancy I used to have hair loss but not this much. Need help. I also have lots of Gray hair Postpartum hair loss is a normal and temporary situation and there is no need to panic. In fact, most women will return to their usual hair growth cycle between 6 and 12 months after birth. During pregnancy, increased levels of estrogen prolong the growing stage. There are fewer hairs in the resting stage and fewer falling out each day, so you have thicker, more luxuriant tresses. After giving birth, the estrogen levels take a tumble and a lot more hair follicles enter the resting stage. It is very common to experience excessive hair loss around three months after delivery. Within six to twelve months after delivery is when most women find that their hair has once again reached a normal state.
