Dandruff is a common scalp disorder that occurs when dead skin cells cluster together and detach from the scalp, forming shedded flakes. A small amount of flaking is normal, but some people experience itching, redness, scaling, and irritation. Dandruff may fluctuate in severity, becoming worse in the winter and with stress.

Several factors can contribute to the onset or increase of dandruff, including age, gender, weather, and preexisting conditions.

Dandruff cannot be cured, but its symptoms can generally be controlled with specialized shampoos. Most people need repeated or long-term, consistent treatment. Selsun blue® helps control dandruff by powerfully relieving symptoms like flaking and itching.

Flakes are clumps of dead skin cells that group before shedding from the scalp. Flaking is typically associated with the overproduction of skin cells.

If you suffer from dandruff, you’re not alone—dandruff occurs in 15–20% of the population, generally anytime from puberty to around age 40.
