Alopecia Areata
Alopecia Circumscripta
📋Overview
Alopecia areata is an autoimmune disorder characterized by sudden, non-scarring hair loss in well-defined patches. It is a modern term; no widely used legacy or eponymous terms apply. The immune system mistakenly attacks hair follicles, leading to hair loss primarily on the scalp but potentially affecting other hair-bearing areas.
