Context: Treatment of resistant alopecia areata (AA) can be very challenging and include many options with variable efficacy and safety profiles. The 308-nm excimer lamp has been claimed to offer an effective alternative without significant risks, though there exists a lack of guidelines in this setting. Aims: This study aimed to evaluate the efficacy and safety of the 308-nm excimer lamp in treating resistant AA in Iraqi patients. Settings and Design: A prospective interventional study. Subjects and Methods: Eighteen patients with multiple AA were enrolled in this study. All patients were treated with a 308-nm monochromatic excimer lamp, in two sessions per week for 12 weeks. The efficacy of this modality was evaluated using two methods, namely the Severity of Alopecia Tool (SALT) score and digital photographs which were taken at four points (baseline, 4 weeks, 8 weeks, and 12 weeks). The safety of the equipment was evaluated by the objective recording of adverse reactions and patient satisfaction. Follow-up continued for 6 months after treatment to assess the level of recurrence. Statistical Analysis Used: SPSS software version 23. Results: There was a statistically significant decrease in the SALT score from the baseline (range 11–30; mean 20.33 ± standard deviation [SD] 4.78) to 12 weeks (range 2–24; mean 9.11 ± SD 5.41) (P < 0.001). The overall response rate was 100%, and successful (>50%) regrowth of hair was seen in 55.5% of patients (n = 10). Younger patients responded to the treatment more than the older age group (P < 0.05). No significant side effects were recorded. Conclusions: The results suggest that 308-nm excimer light has a significant effect on resistant cases of multiple AA, with considerable safety and tolerability.
