To combat dry scalp and dandruff, I recommend incorporating a few changes into your hair care routine. First, use a moisturizing shampoo and conditioner formulated for dry scalp. Avoid hot water when washing your hair, as it can strip away natural oils. Gently massage your scalp while shampooing to promote circulation and exfoliation. Try using a hydrating hair mask or oil treatment once a week to nourish your scalp and hair. Additionally, maintain a balanced diet rich in omega-3 fatty acids and drink plenty of water to promote scalp health from the inside out. If the issue persists, consider consulting a dermatologist for personalized advice.
