Alopecia areata is an autoimmune condition that causes sudden hair loss in small, round patches on the scalp or other areas of the body. It occurs when the immune system mistakenly attacks the hair follicles, leading to hair shedding.

The exact cause is unknown, but it is believed to be an autoimmune response which occur in people who are predisposed genetically, and can be triggered by environmental factors, such as psychological stress and illnesses. It is not contagious.

Yes, hair loss may remain localised to small patches or, in rare cases, progress to complete scalp hair loss (alopecia totalis) or full-body hair loss (alopecia universalis).

Hair may regrow spontaneously, and small patches have good prognosis with regrowth either spontaneously or through treatments. In more severe cases however, spontaneous regrowth is more difficult and will need oral medication. Alopecia areata can recur.

✔ Topical treatments – Corticosteroids, minoxidil, or JAK inhibitors.

✔ Injectable treatments – Corticosteroid injections.

✔ Oral medications – Corticostseroid, JAK inhibitors or immunosuppressive for more severe cases.

Yes, stress can trigger or worsen flare-ups, though it is not the sole cause. Managing stress through lifestyle changes, mindfulness, and a healthy routine may help reduce recurrence.

There is no permanent cure, but many treatment options can help stimulate hair regrowth and manage symptoms.

Alopecia areata does not cause physical health problems, but it can impact self-confidence and emotional well-being. Seeking support and treatment can help improve quality of life.
