Silk shine For the hair, oil treatments once or twice a week are a must. Heat almond oil and apply on the scalp and hair. Dip a towel in hot water, squeeze out the water and wrap the towel around the head, like a turban. Keep it on for five minutes. Repeat the hot towel wrap three or four times. This helps the hair and scalp absorb the oil better. Weekly henna treatments will help condition the hair and add body and shine. If your hair is oily, give yourself a lemon rinse. To nourish dry hair, massage egg yolk or mayonnaise. Into the scalp. Leave it on for half an hour and then wash off.
