If you have a normal delivery, you can wash your hair and take a bath in about 7 days if you are recovering well; if you have a cesarean section, you will need to wait for your abdominal wounds to heal before washing your hair and taking a bath, and it will take about 7 to 15 days. Menstruation is the common name for the puerperal period, during which a woman’s skin excretes more vigorously and she sweats easily. However, women’s resistance is low during this period, so washing hair and taking a bath need to wait until the wounds of the delivery have healed. Depending on the mode of delivery, the healing time of labor wounds varies. Usually, the recovery time is shorter for women who have had a normal delivery and longer for women who have had a cesarean section due to the presence of wounds in the abdomen. During the puerperium, the exact time for washing hair and taking a bath depends on the individual’s wound healing condition. Avoid washing hair and taking a bath when the wound is not yet healed to prevent bacteria from invading and causing wound infection. When you wash your hair and take a bath during the puerperium, you need to control the time, pay attention to warmth, blow-dry your hair and dry your body in time to avoid getting cold.
