Dandruff is a typical scalp condition marked by white flakes on the scalp and itching. A possible cause is a yeast-like fungus called malassezia, also known as pityrosporum. Malassezia is normally discovered on the scalp without triggering problems, however, if it grows unattended (perhaps due to hormone imbalances, anxiety, immune suppression, seldom shampooing, illness, or increased oil production), there is moderate inflammation that produces dead skin cells.

The dead cells blend with oil and clump together, making them appear white and flaky.
