Eating calcium tablets is useful for postpartum hair loss. A lack of calcium can also cause hair loss, and calcium tablets can effectively provide the calcium needed by the body. 99% of the calcium in the human body is found in teeth and bones, and if not paid attention to, calcium deficiency is not the main cause of hair loss. Clinically, it is mainly caused by changes in hormone levels in the body and some emotional and psychological factors. Therefore, taking calcium tablets is useful for postpartum hair loss, but it is necessary to identify some related factors causing the hair loss. It's important to maintain a good mood, strengthen nutrition, massage the scalp with a wooden comb, or rhythmically tap the head to promote blood circulation in the scalp.
