Alopecia areata is the condition affecting Jada Pinkett Smith, who found herself at the center of the Will Smith-Chris Rock conflict at the Oscars ceremony Sunday. Dr. Brett King answers FAQs about the causes, severity, challenges, treatments and more.
Pinkett Smith has shared publicly that she has alopecia areata, an autoimmune disease that causes hair loss on the scalp and elsewhere, according to the National Alopecia Areata Foundation. Hair follicles affected by the disease are mistakenly attacked by a person's immune system, which stops hair growth.
