1. Washing hair or bathing during menstruation is acceptable provided the body remains warm and the environment is comfortably heated. However, it's best to avoid washing in the first few days of menstruation, waiting instead until flow has slightly decreased. This approach safeguards against exposure to cold drafts while maintaining personal hygiene. Warm water must be used 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. If you wash your hair at night and don't dry it thoroughly, moisture will linger on your scalp and condense overnight. Over time, this can lead to qi stagnation, blood stasis, and blocked meridians.In winter, the combination of cold and dampness makes illness even more likely. Therefore, it's best not to wash your hair before bed. If you must wash it, ensure your hair is completely dry before sleeping. 3. During your period, it's best to wash your hair or take a bath 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 bathe 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 bodies have lower resistance during menstruation, making proper care essential. Neglecting this may adversely affect health. Therefore, it's best to avoid washing your hair during menstruation. If unavoidable, avoid washing during the first three days. Use warm water, not cold.
