What is the medical term used to describe dandruff?

• A. Pityriasis
• B. Psoriasis
• C. Seborrhea
• D. Tinea

Answer: (A)

Dandruff is described medically by a term that refers to scaling or flaking of the skin on the scalp. That term is pityriasis, which in the scalp context is often written as pityriasis capitis to denote dandruff. So this choice is the best fit because it directly names a condition characterized by flaky scales on the scalp. The others point to different skin issues: psoriasis is a chronic inflammatory skin disease with thick silvery scales; seborrhea means excessive oiliness that can accompany flakes but isn’t the specific label for dandruff itself; and tinea refers to fungal infections such as ringworm.
