The skin on the scalp is lubricated naturally. A dry scalp is often the result of other conditions that rob moisture from the head. Skin conditions, poor diet, over-processed hair and excessive heat can inhibit moisture replenishment in the scalp. To moisten your scalp, it is best to treat these underlying conditions.
Make an appointment and see your doctor. Request tests of your hormone levels and other routine health tests to ensure that your dry scalp isn't due to another health problem. Show the doctor your dry scalp to rule out eczema and other skin conditions. Treat any conditions according to your doctor's recommendations.
Wash and condition your hair with products that contain keratin, urea, butters and oils. Stay away from silicone, petroleum and sulfate products that can dry out the scalp. These chemicals also coat the hair and scalp, building up over time. They do not wash away easily with routine shampooing.
Drink plenty of water each day to give your body enough moisture to replenish scalp moisture. Take daily vitamins E, B6 and B12, which help the skin to replenish moisture. Eat a balanced diet that includes omega-3 fatty acids, as this will help produce a healthy scalp and skin.
Apply a hot oil treatment (found at any drug store) once a work to keep your hair and scalp moist. Use a cream hair and scalp moisturizer for kinkier hair to provide additional moisture to the hair and scalp. Part the hair and place the cream moisturizer directly on the scalp. Kinky and tightly coiled hair is often drier and requires more moisture than straighter hair types.
