Washing your hair correctly is crucial during winter. Use lukewarm water instead of hot water to avoid stripping natural oils from your scalp. Wash your hair two to three times a week with a mild, sulfate-free shampoo applied only to the scalp. Follow up with a conditioner on the lengths and ends, and gently pat your hair dry with a soft cotton towel. Never step outside with wet hair, as it can lead to damage and discomfort in cold weather.
