Alopecia areata (AA) is a very common autoimmune disease that leads to unpredictable, relapsing patchy hair loss. Its chronic pathophysiology is still not fully understood. Hair follicles are not destroyed permanently due to which the potential for regrowth of hair is retained for many years, and is possibly lifelong. Clinical presentation varies from small alopecia patches most commonly on the scalp to full body involvement. Characteristic “swarm of bees” appearance on histopathology is confirmatory in acute cases. A variety of therapeutic options are available, but search for new modalities continues as there is a high relapse rate and a number of side effects associated with the available treatment options.
