Cedarwood is great for flaky scalp. Mix essential oils of cedarwood (seven drops) cypress and juniper (each ten drops) in 50ml of carrier oil. Rub well into the scalp and leave for one hour. To remove, rub neat, mild shampoo into the hair, then wash out with warm water.To keep dandruff at bay, use the same quantities of the oils in 600ml of warm water. Stir well and use as a final rinse.
