Alopecia areata
Alopecia areata is an autoimmune disease in which an individual's hair follicles are mistakenly attacked by their own immune system, causing arrest of hair growth. It can rarely be associated with other autoimmune diseases, therefore, a thorough history, physical, and sometimes laboratory evaluation, is needed. It appears as smooth, round, bald spots. It can be localized with just a few spots in the scalp and/or beard area or can progress to total hair loss of the scalp (alopecia totalis) or complete body hair loss (alopecia universalis).
