Excimer Lamp as an Effective Alternative Treatment for Severe Alopecia Areata

The study evaluated the efficacy of a 308-nm excimer lamp in treating alopecia areata (AA) in 17 patients, finding an overall response rate of 41.2% and a satisfactory response (more than 50% hair regrowth) in 29.4% of patients. Patients with severe AA (≥50% hair loss) had a 50% response rate, with improvements typically observed after 2 months of treatment. Mild side effects included erythema and pruritus. The study concluded that the excimer lamp was a safe and effective alternative treatment for AA, especially in severe cases, despite limitations such as the small sample size and retrospective nature.
