Precautions for Washing Hair During Menstruation
1. Washing hair or taking a shower during menstruation is acceptable provided the body remains warm and the environment is comfortably heated. However, it is best to avoid washing during the first few days of menstruation. Wait until menstrual flow has slightly decreased before proceeding.
This approach ensures clean hair while preventing exposure to cold air. Crucially, always use warm water for both washing hair and bathing.
2. Washing hair right before bed—especially going to sleep with damp hair—is highly likely to cause colds and menstrual headaches.
