What causes dandruff?

KDAH

Dandruff or white flakes, is often caused by the overgrowth of a yeast-like fungus called malassezia on the scalp. This overgrowth can lead to irritation and increased shedding of skin cells. Other factors include dry skin, sensitivity to hair products, and infrequent shampooing. Maintaining a healthy scalp routine can help keep dandruff under control.
