Alopecia Areata Treated Using CO2 Fractional Laser With Different Parameters

This case study explores the use of CO2 fractional laser treatment with varying parameters on a 13-year-old male with alopecia areata (AA). The patient, who had previously experienced suboptimal results with tofacitinib, was treated with oral prednisone, compound Siyadan ointment, and CO2 fractional laser therapy. The laser treatment was applied to nine different areas with varying energy and depth settings, while one area was left untreated as a control. After three months, the patient's lesions fully resolved, with hair growth observed in all treated areas, including the control. The study highlights the potential of CO2 fractional laser in treating AA, though it emphasizes the need for further research to establish optimal treatment parameters.
