Dandruff occurs when natural oils, or sebum, that are present and necessary to the scalp’s health, break down and leave a dry, flaky skin surface. Often leaving dry flakes on the shoulders and clothes, and an unsightly appearance at the hairline and parting, it can be an uncomfortable and embarrassing problem that many people would like to address. Fortunately a vast range of anti-dandruff shampoos, creams and oils are available, to tackle your worries and help to soothe and repair the scalp.
