Postpartum hair loss is not largely related to iron deficiency. It is mainly due to significant hormonal changes in postpartum women. A drop in estrogen levels causes hair follicles to enter the shedding phase. Moreover, the mental stress associated with postpartum life, combined with the fatigue of caring for a baby, can exacerbate hair loss. The most severe period of hair loss occurs 3 to 4 months after delivery, and generally, by 6 to 12 months postpartum, the condition tends to improve and usually does not require special treatment. In daily life, it is beneficial to consume foods rich in protein and vitamins to help improve this condition. In cases of severe hair loss, medication can also be taken under the guidance of a doctor.
