What is the technical term for dandruff?

Dandruff is scientifically referred to as pityriasis, which denotes the condition characterized by the shedding of flakes from the scalp. The term comes from the Latin "pityriasis," which means "scurf" or "dandruff." This condition can be caused by a variety of factors, including dry skin, fungal infections, or sensitivity to hair products, all leading to increased skin cell turnover and flaking.

The other terms listed have distinct meanings that do not apply to dandruff. Scutula refer specifically to crusty lesions typically associated with a fungal infection, monilethrix is a genetic condition that results in brittle hair, and helix pertains to the ear's outer structure or a spiral shape in anatomy, none of which relate to the context of dandruff. Understanding these terms helps in distinguishing between different conditions affecting the scalp and hair health.
