Alopecia Areata: Symptoms, Causes, Treatment & Hair Regrowth

Alopecia areata is an autoimmune condition that causes sudden, patchy hair loss on the scalp, face, or body. It affects people of all ages and can be emotionally distressing, but many patients experience regrowth with proper treatment. The condition occurs when the immune system mistakenly attacks hair follicles, halting hair production. It is not contagious and is often unpredictable, with periods of hair loss and regrowth.

• Round or oval smooth bald patches on the scalp or beard
• Sudden hair loss that may progress or resolve spontaneously
• “Exclamation mark” hairs at patch edges
• Possible nail pitting or changes
• In severe cases (alopecia totalis or universalis): total scalp or body hair loss

The hair loss is usually painless but can be accompanied by tingling or itching.

Alopecia areata is autoimmune, with genetic and environmental factors. Triggers may include stress, illness, or viral infections. Family history increases risk. It is not caused by diet or poor hygiene.

Treatment depends on extent and patient age:

• Topical or injected corticosteroids
• Topical immunotherapy (e.g., diphencyprone)
• JAK inhibitors (oral or topical) for moderate to severe cases
• Minoxidil for supportive regrowth
• Observation for mild, limited patches (many regrow spontaneously)

Newer therapies have significantly improved outcomes for extensive alopecia areata.

• Manage stress through relaxation techniques
• Protect bald areas from sun with hats or sunscreen
• Use gentle hair care and avoid tight styles
• Join support groups for emotional support
• Follow up regularly with a dermatologist

Seek care for any sudden patchy hair loss. Early treatment can help limit progression and promote faster regrowth.
