I am losing hair after pregnancy. Can I reverse it?Hair loss after pregnancy is quite common. It is caused by hormonal changes that cause the growth phases of the hair to go out of sync. As a result you can experience excess hair loss some months after giving birth. Usually the hair growth phases will get back into sync and the hair will regain its original thickness but sometimes this does not occur and the hair can remain thin or get even thinner. The condition can be worsened by increased stress and reduced sleep (due to caring for the baby at night). The combination of increased stress and much less sleep can result in a reduction of nutrients available to feed the hair because the body is drained of nutrients.
