About Alopecia Areata

Alopecia areata is an autoimmune dermatologic condition, typically characterized by patchy, non-scarring hair loss on the scalp and body. The National Alopecia Areata Foundation reports that over 6.6 million Americans have had or will develop alopecia areata at some point in their lives. There is currently no FDA-approved medical treatment for this autoimmune disease. However, it has been reported that systemically administered JAK inhibitors may be potentially efficacious in the treatment of alopecia areata.
