Objective: Alopecia areata (AA) is characterized by patchy non-scarring hair loss involving the scalp and other hair-bearing surfaces. This study aims to determine the effectiveness of 308-nm Excimer laser in patients with alopecia areata.
Methods: A total of 168 patients with alopecia areata (within 12 months) were included in the study in a consecutive manner and subjected to 308-nm Excimer laser. Baseline and follow up Severity of Alopecia Tool (SALT) scoring was done to determine the effectiveness of the therapy.
Results: The mean baseline SALT score was 26.4±13.3 which increased to 75.6±12.7 (p <0.001). The mean difference between baseline and follow up SALT score was 49.2±12.7. According to categories of difference between baseline and follow up SALT scoring, 41.7% were in fair category (11-50) and 58.3% were in excellent category (SALT 51-74). Effectiveness (minimum 50 improvements in SALT from baseline) was recorded in 58.3% of patients. Erythema was the only side-effect noted in our study.
Conclusion: 308-nm Excimer laser is effective in the treatment of alopecia areata and is significantly associated with improvement in baseline SALT score.
