In children and adults, for mild dandruff on the scalp, eyebrows, or beard area, using a dandruff shampoo may be all that you need to treat the problem. The active ingredients in these shampoos all work to varying degrees; it may be worthwhile to try out a few shampoos to see which works best for you. Dandruff around a beard or moustache can often be improved simply by shaving the area.
Dandruff on the body can be treated by exposing the skin to moderate amounts of sunlight, which is thought to reduce the population of dandruff-inducing yeast in the area. For more severe dandruff that doesn't respond to over-the-counter products, your doctor may prescribe stronger medications containing corticosteroids.
