Efficacy of Fractional CO2 Laser as a Mono- or Adjuvant Therapy for Alopecia Areata

Summary

Alopecia areata is a non-scarring hair loss disorder that affects both sexes equally. Incidence of the disease varies for different populations and in different studies, with global incidence ranging from 0.57% to 3.8%. Etiology of alopecia areata is not completely understood, and the majority of evidence suggests that genetically predisposed individuals, when exposed to an unknown trigger, develop a predominantly autoimmune reaction, leading to acute hair loss. Environmental triggers, including viral or bacterial infections, along with autoimmune disorders, seem to play a major role in the development of alopecia areata.
