Alopecia areata is a medical disease

Alopecia areata (AA) is a common autoimmune disease characterized by nonscarring hair loss that affects all ages, both sexes, and all skin types. Despite significant advances in understanding the pathomechanism of the disease, the autoimmune comorbidities, and how quality of life (QoL) is affected, treatment for AA is still not considered medically necessary by many insurers and even some physicians.
