Introduction
If menstrual flow is normal, and there are no significant discomforts such as severe dysmenorrhea, dizziness, or fatigue, it is generally safe to wash hair during menstruation. Use warm water when washing and promptly dry the hair thoroughly with a hair dryer afterward, avoiding prolonged periods with wet hair. This helps minimize the risk of catching a chill and typically does not have any noticeable negative impact on menstrual health.

Generally, if there are no obvious discomforts during menstruation and proper warmth is maintained, washing hair is acceptable. However, it is advisable to postpone hair washing if the body feels weak or adequate warmth cannot be ensured. If in doubt, it's recommended to observe your physical condition beforehand. Detailed explanations are as follows:

If menstrual flow is normal and there are no severe symptoms such as dysmenorrhea, dizziness, or fatigue, using warm water to wash hair and thoroughly drying it immediately afterward with a hairdryer—avoiding prolonged dampness—usually allows for safe hair washing. Using warm water and prompt drying helps reduce the risk of catching a chill, thus having no significant impact on menstrual health.

If menstrual flow is excessively heavy, or accompanied by severe menstrual pain, lower back soreness, body aches, dizziness, or other discomforts, and if it's difficult to stay warm after washing hair, it is recommended to delay washing. During this time, the body’s resistance is relatively low; getting chilled may worsen symptoms and could even affect menstrual blood discharge. It is safer to wait until physical condition improves before washing hair.

During menstruation, always use warm water for washing hair—never cold water. Dry hair as quickly as possible afterward to prevent exposure to cold. If any discomfort occurs after washing hair, apply immediate warming measures, monitor symptoms closely, and consult a healthcare professional if necessary.
