Alopecia areata

Abstract

Alopecia areata (AA) is a non-scarring hair loss condition that affects individuals of all ages and ethnic backgrounds. It is thought to be autoimmune in nature, but the exact cause is not yet known. This condition is usually asymptomatic and the patches are discovered incidentally in most patients. Scalp is the site most commonly affected by AA. AA patients have slightly higher chances of developing some other autoimmune conditions. There are no FDA-approved treatments for AA. Our treatment options aim to control the disease but none is curative. Despite the fact the treatment options for AA remained without major breakthroughs over the last few decades, recent understanding of the genetic structure of AA may carry newer management ideas. Addressing the psychological impact of the disease is of paramount importance in the management. This chapter will review the clinical picture and management of AA paying special attention to the pediatric age group.
