What Is Alopecia Areata?
Quick answer: Alopecia areata is an autoimmune condition where the immune system attacks hair follicles, typically causing smooth round patches of hair loss; it needs a doctor’s diagnosis, and hair often regrows, though it can recur.
- Signs: Round smooth patches, sometimes in beard or brows.
- Treatment: Dermatologists have medical options.
- Cosmetic support: After medical care, cosmetic options may help confidence.
