To control oily hair and scalp, it is essential to maintain a proper care routine. Use a shampoo designed for oily hair and scalp that is gentle and does not contain harsh ingredients. Avoid excessive use of conditioner and refrain from applying it directly to the scalp. Wash your hair with lukewarm water instead of hot water, as heat can stimulate the sebaceous glands. Try not to touch your hair and scalp with your hands frequently, as this can transfer oil and dirt. Additionally, maintain a balanced diet and avoid fatty foods. If the problem persists, it is advisable to consult a professional in hair health for specific guidance and treatment.
