Other people lose hair because their immune system starts attacking their hair follicles in what is known as autoimmune alopecia. Autoimmune forms of alopecia can be caused by discoid lupus erythematosus, which can lead to sores and scarring on the face and scalp. Central centrifugal cicatricial alopecia is another immune-related condition that causes scalp scarring and permanent hair loss. C.C.C.A. almost exclusively arises among Black women between ages 30 and 55, and research suggests it may afflict as many as 15 percent of such women.
