Introduction

Alopecia areata is a type of hair loss that affects both men and women of all ages. It is an autoimmune disorder in which the body’s own immune system attacks the hair follicles, resulting in hair loss. It can affect any part of the body, but is most commonly seen on the scalp. Symptoms of alopecia areata can range from small, round patches of baldness to complete hair loss on the head and body.

The cause of alopecia areata is unknown, but it is believed to be an autoimmune disorder triggered by stress or underlying health conditions. Treatment for the condition can vary, depending on the severity of the hair loss. Topical medications, such as corticosteroids, can be used to treat smaller areas of hair loss. For more severe cases, oral medications, such as minoxidil, may be prescribed. Other treatments, such as light therapy, may also be recommended.
