What is the technical term for dandruff?

  1. Vellus

  2. Pityriasis

  3. Scalp dermatitis

  4. Trichorrhexis

The correct answer is: Pityriasis

The technical term for dandruff is Pityriasis. This term refers to the condition characterized by the shedding of dead skin cells from the scalp, which can manifest as white or yellow flakes. Pityriasis is derived from the Latin word "pityrus," meaning "bran," which reflects the scaly appearance of flaky skin that resembles bran. Understanding Pityriasis as a condition helps to identify its causes, which can include factors such as dry skin, oily skin, or fungal infections like Malassezia. Recognizing the term is important for both diagnosis and treatment, as it allows for clearer communication between professionals and understanding the nature of the condition. The other terms provided do not pertain specifically to dandruff. Vellus refers to fine, soft hair typically found on the body. Scalp dermatitis is a broader term encompassing various inflammatory conditions of the scalp, which may include dandruff but also includes other types without the specific characteristics of Pityriasis. Trichorrhexis refers to a defect in the hair structure, which is unrelated to the shedding of skin cells found in dandruff.
