An autoimmune condition where the immune system targets hair follicles, causing round patches of sudden hair loss. Most cases are self-limiting and the hair regrows. Some don't — and that's where the honest conversation begins.
Alopecia areata occurs when the immune system mistakenly attacks hair follicles, halting hair production in the affected area. The classic presentation: round, smooth, well-defined patches of sudden hair loss, typically on the scalp but possible anywhere on the body. The skin underneath looks normal — no scarring, no inflammation, no itch.
The condition affects roughly 2% of the population at some point in their lives, often beginning in childhood or young adulthood. There’s a genetic component, and a connection to other autoimmune conditions (thyroid, vitiligo, type 1 diabetes), but the precise trigger for any individual episode is usually unknown — sometimes stress, sometimes nothing identifiable.
There are several variants: alopecia areata (patchy), alopecia totalis (entire scalp), and alopecia universalis (entire body including eyelashes and brows). The patchy form is by far the most common.
About half of patchy cases regrow spontaneously within twelve months without treatment. The hair often grows back fine and white at first, then thickens and re-pigments over the following months. Some people experience a single episode and never another; some have recurring episodes throughout life.
For active cases, dermatologists typically prescribe corticosteroid injections at the patches (effective at stimulating regrowth in localised cases), topical immunotherapy, or — for more extensive cases — newer JAK-inhibitor medications. Treatment decisions belong with a dermatologist; this is not surgical territory until the disease is clearly stable.
Hair transplant is not appropriate for active alopecia areata — the immune system that attacked the original follicles will attack transplanted ones too. The disease must be stable first. Stability typically means several years without new patches, no active inflammation, and a dermatology assessment confirming the disease is in long-term remission.
For patients with stable, scar-pattern alopecia areata in cosmetically sensitive areas (eyebrows, hairline, beard), transplant can dramatically improve appearance. The transplanted follicles, being themselves DHT-resistant scalp hair, are not targeted in the same way as the original follicles — so the result is generally durable.
If you’re considering surgery for alopecia areata, the right first step is a dermatology assessment confirming long-term stability, then a photo consultation with us. We’ll review the dermatology notes and your goals before recommending anything.
