Alopecia areata is an autoimmune condition that causes sudden hair loss in round or oval patches on the scalp or other parts of the body. It occurs when the immune system mistakenly attacks hair follicles, leading to non-scarring hair loss. The condition can affect people of any age, including children and young adults.
The most common symptom of alopecia areata is smooth, bald patches on the scalp. Some individuals may notice excessive hair shedding, thinning of eyebrows or beard hair, or nail changes such as pitting. In severe forms, hair loss may involve the entire scalp (alopecia totalis) or the whole body (alopecia universalis).
The exact cause of alopecia areata is not completely understood, but genetic predisposition, stress, thyroid disorders, and other autoimmune diseases may contribute. Though the condition is not contagious or life-threatening, it can significantly affect self-confidence and emotional well-being.
Diagnosis is usually based on clinical examination by a dermatologist. Dermoscopy and blood investigations may sometimes be required to identify associated conditions. Treatment depends on the severity and extent of hair loss. Common treatment options include topical corticosteroids, intralesional steroid injections, topical immunotherapy, minoxidil, and oral medications in selected cases.
Many patients experience spontaneous regrowth, but relapses are common. Early treatment often improves outcomes and helps reduce progression. Proper counselling and emotional support are equally important, especially for young patients.
