Postpartum hair loss can occur but it typically grows back. This type of hair loss is mainly due to the decline in estrogen and progesterone levels in women after childbirth, which causes the hair follicles to lose some nourishment, leading to hair loss. Additionally, the stress, fatigue, and emotional instability that often follow childbirth can also contribute to postpartum hair loss. Generally, postpartum hair loss stops about six months after childbirth. Through proper postpartum care, getting adequate rest, improving nutrition, and maintaining a good mood, the hair generally grows back quickly.
