Alopecia areata is an autoimmune condition in which the immune system attacks hair follicles, causing hair loss that often appears in round patches. It can affect the scalp, beard, eyebrows, or other areas.
Key points
- Hair loss can be sudden
- Some people experience regrowth, while others have ongoing or expanding loss
- It is not contagious and not caused by stress alone (though stress may play a role in some cases)
- Nail changes can occur in some individuals
Treatment
Options depend on the extent of loss and may include corticosteroid injections or topicals, topical immunotherapy, minoxidil, and newer systemic treatments for more extensive disease. A dermatologist can discuss what is appropriate for your situation.
