Postpartum hair loss is generally due to unstable hormone levels during pregnancy and a significant reduction in estrogen secretion during the postpartum recovery phase, which can lead to hair loss. Emotional instability, psychological stress, or dietary adjustments after childbirth can also cause metabolic disorders and lead to hair loss. Normally, not all hair is lost; the extent of hair loss varies from person to person. After childbirth, it is still necessary to have a nutritious diet, engage in appropriate exercise, and regularly supplement with trace elements to influence normal hair growth and alleviate hair loss.
