Alopecia areata is an autoimmune condition where immune system mistakenly attacks hair follicles, leading to hair loss.

It is commonly characterized by patches of complete loss of hair over scalp, eyebrows, beard or any part of the body.

Treatment options include injections, topical immunotherapy and oral medications aimed at suppressing the immune response and stimulate hair regrowth.

For personalized diagnosis and treatment, consult a dermatologist.
