Alopecia areata treated using CO₂ fractional laser with different parameters

Area of Science:

• Dermatology
• Laser Therapy
• Trichology

Background:

• Alopecia areata (AA) is an autoimmune condition causing hair loss.
• CO2 fractional laser therapy shows promise for AA treatment, but large-scale comparisons are lacking.
• Optimal treatment parameters for CO2 laser in AA require further investigation.

Purpose of the Study:

• To present a case study on the efficacy of CO2 fractional laser in treating pediatric alopecia areata.
• To evaluate the combined effect of medical and laser therapies for AA.
• To observe the impact of varying CO2 laser parameters on hair regrowth in AA.

Main Methods:

• A 13-year-old male with AA received a combination therapy.
• Medical treatment included oral prednisone acetate and compound Siyadan ointment.
• CO2 fractional laser treatment was administered monthly with diverse parameters across different lesional areas.

Main Results:

• Complete resolution of AA lesions was achieved after three months of combined treatment.
• Significant hair regrowth was observed in the treated areas.
• Variations in hair growth density and coverage were noted correlating with different CO2 laser parameters used.

Conclusions:

• Combined therapy of CO2 fractional laser, oral prednisone acetate, and topical Siyadan ointment can be effective for pediatric AA.
• The study highlights the potential influence of CO2 fractional laser parameters on treatment outcomes in AA.
• Further research with larger cohorts is warranted to establish optimal laser settings for AA management.
