Overview of the Role of 308 Monochromatic Excimer Phototherapy for the Treatment of Alopecia Areata

The document discusses the use of 308 monochromatic excimer phototherapy for treating Alopecia Areata (AA), a hair loss condition. This therapy, which uses a UVB light source, works by inducing apoptosis in T cells and has been successful in treating both adults and children with moderate-to-severe AA. The document reviews various studies with different participant numbers, generally concluding that the therapy is safe and effective, though results can vary. The treatment protocol involves administering the therapy one or two times per week until a clinical response is observed, with the treatment continuing for 12 weeks (24 sessions). The document concludes that 308 excimer phototherapy is a safe and effective treatment for AA, requiring a shorter treatment duration than whole-body phototherapy.
