Is it better to wash your hair in the morning or in the evening?

Generally speaking, there are appropriate situations for both morning and evening hair washing. If there is sufficient time in the morning to wash and promptly dry the hair, it is suitable to wash in the morning. However, it is not advisable to wash hair in the evening if one goes to sleep without thoroughly drying the hair afterward. If any abnormalities occur, it is recommended to seek medical advice promptly. Detailed analysis is as follows:

Washing hair in the morning allows sufficient time to completely dry the hair afterward, helping one start the day feeling refreshed. It is especially suitable for those with regular schedules and ample time in the morning. At this time, washing hair will not cause discomfort due to damp hair and may even improve mental alertness, with no adverse effects on daily activities.

Going to bed with damp hair after washing in the evening might cause the head to become chilled, or lead to bacterial growth on the pillow. Long-term practice of this habit may cause scalp discomfort or headache. Particularly in cold weather, sleeping with wet hair is not conducive to keeping the head warm, making this an unsuitable time for evening hair washing.

The timing of hair washing should be based on individual schedules. Regardless of whether it is morning or evening, ensure the hair is completely dry before exposure to cold air or prolonged contact with the pillow.
