What happens if alopecia areata is not treated?

Alopecia areata causes the immune system to target hair follicles. A small bald patch can stay unchanged, enlarge, or be joined by new patches. Hair loss may involve the scalp, beard, eyelashes, or eyebrows; thinning eyebrows can affect the appearance of the brow and, when lashes are affected, reduce protection from dust. The skin usually looks smooth rather than scarred, and follicles may remain capable of producing hair. The course is unpredictable, and emotional distress can become significant even when the scalp feels normal.

Arrange an assessment when you notice new Bald Patches or unexplained Hair Loss. A clinician can examine the scalp, review medicines and health history, and check whether another cause needs consideration. Options may include Topical Corticosteroids, Steroid Injection Into The Skin for selected patches, or JAK Inhibitor Treatment when appropriate. Oral Corticosteroid Treatment may be considered in particular situations, with medical supervision. Take photos in consistent lighting to track change without repeatedly pulling at the hair.

Seek prompt care if patches are enlarging quickly, eyebrows or eyelashes are thinning, or hair loss is accompanied by scalp pain, scaling, redness, or broken hairs. Urgent review is appropriate for sudden extensive hair loss with other new symptoms. Early assessment helps distinguish alopecia areata from infection, inflammation, or traction-related loss.

Could this be alopecia areata or another cause of hair loss? Which areas should I monitor? What benefit and risks apply to each treatment option? How will we judge whether treatment is helping?
