Alopecia Areata Treatment

Alopecia areata is an autoimmune condition in which the immune system attacks hair follicles, causing round or oval patches of hair loss. It can affect the scalp, beard (alopecia barbae), eyebrows, eyelashes and body hair.

Its course is unpredictable: patches often regrow on their own, new patches can appear, and some people have repeated episodes. Treatment aims to encourage regrowth and calm the condition; it cannot cure it or promise that hair loss will not return.

How is alopecia areata diagnosed?

Diagnosis is usually made by examining the patches, often with a dermatoscope. Blood tests may be advised to check for related conditions such as thyroid disease.

Which treatments are used for alopecia areata?

• Corticosteroid injections – injected into the patches to suppress the immune reaction; commonly used for limited patchy loss.
• Topical treatments – steroid creams or lotions, and minoxidil, often used together with other treatments.
• Oral medicines for extensive or persistent disease – including immune-modulating drugs and, in some severe cases, newer medicines called JAK inhibitors, which need medical supervision and monitoring.
• PRP and GFC – sometimes used for patchy loss, although the evidence is limited and they are not first-line treatment.
• Low-level laser therapy – occasionally used alongside other treatments; the evidence is limited.

The choice depends on how many patches you have, how long they have been present and how active the condition is. A hair transplant is not a treatment for active alopecia areata, because transplanted hair can be lost in the same way.

What results can you expect?

Regrowth, when it happens, usually takes a few months to appear, and new hair may come through fine or white at first before regaining its colour. Some patches do not respond, and extensive or long-standing hair loss is harder to treat. Side effects depend on the treatment — steroid injections, for example, can cause a temporary dent in the skin at the injection site — and are discussed before you start.

Who should seek treatment for alopecia areata?

• Anyone with a new bald patch, to confirm the diagnosis
• People with patches on the scalp, beard, eyebrows or eyelashes
• People whose patches are spreading or keep coming back
