1. Washing your hair or taking a bath during menstruation is acceptable as long as you stay warm and the environment is comfortably heated. However, it's best to avoid doing so in the first few days of your period. Wait until flow has slightly decreased. This ensures your body remains protected from wind and cold while maintaining cleanliness. Always use warm water for washing hair or bathing, even during exceptionally hot summers.
2. Avoid washing your hair right before bed. Washing your hair before sleep, especially going to bed with wet hair, is the easiest way to catch a cold or trigger menstrual headaches. As Dr. Peng Kang explains, "Washing your hair at night without drying it properly allows moisture to linger on the scalp. This moisture condenses overnight, and over time, it can lead to qi stagnation, blood stasis, and blocked meridians.In winter, the combination of cold and dampness makes it even easier to develop illnesses." Therefore, it's best not to wash your hair before bed. If you must, ensure your hair is completely dry before sleeping. 3. During your period, it's best to wash your hair or take a shower one to two hours after a full meal to avoid insufficient blood supply to the heart. Choose your bathing time based on your constitution. For example, those with a weak constitution may prefer bathing at noon when yang energy is strongest.
Additionally, avoid washing your hair after drinking alcohol during menstruation, and generally refrain from using excessively cold water. Women's physical resistance is weaker during menstruation than usual, so special care is essential. Neglecting this may adversely affect your health. Therefore, it's best for women to avoid washing their hair during menstruation. If unavoidable, avoid washing during the first three days. When washing, use warm water, not cold.
