Comparison of an Non-ablative Fractional 1565nm vs. an Ablative 2940-nm Fractional Er Laser for the Treatment of Androgenetic Alopecia

Ablative fractional 2940-nm Er: YAG laser (Dermablate MCL31, Asclepion Laser Technologies, Germany), the following parameters were used: model of N25%, energy density of 20-30J/cm2, pulse time of 300μs and one to two passes.

Non-ablative fractional 1565nm (Lumenis, M22): Resur Fx len, energy of 30-35J/cm2, density of 200spot/cm2, overlap ≤10%.
