What is the technical term for dandruff?

The technical term for dandruff is indeed pityriasis. Dandruff is characterized by the shedding of dead skin cells from the scalp, and the condition is often connected to an overgrowth of yeast or a reaction to certain hair care products. Pityriasis specifically refers to the flaking of the skin, particularly in the context of the scalp.

In contrast, seborrhea focuses on an oily condition of the skin, particularly affecting areas rich in sebaceous glands. Eczema refers to a broader category of skin inflammation, leading to red, itchy patches that may be moist or crusty but does not specifically denote the type of flaking associated with dandruff. Dermatitis encompasses inflammation of the skin but is a more general term that includes various skin conditions, not limited to those causing flaking.

Understanding the distinctions between these terms can help clarify the nature of various scalp conditions and their implications for treatment in barbering practices.
