There are several reasons for postpartum hair loss. The most common one is due to women experiencing weakness in their vital energy and blood after childbirth, which fails to nourish the scalp resulting in hair loss. Another reason is the significant hormonal changes in a woman's body after giving birth, which leads to the scalp losing these hormone nourishments, causing the hair to gradually fall out. Additionally, some women experience depression postpartum. Poor mood can also affect the body's metabolism, and hair loss is more likely to occur if nutritional supply is inadequate. Furthermore, if a woman does not promptly nourish and regulate her body after childbirth and instead starts dieting or attempting to lose weight without adequate nutrition, this can lead to insufficient scalp nutrition and affect metabolism, resulting in hair loss.
