TLDR  Higher fluences in 808-nm diode laser treatments are more effective for axillary hair removal.   
  This study evaluated the efficacy of an 808-nm diode laser at different fluences for permanent axillary hair removal in 24 Korean women. The participants received laser treatments at 1-month intervals with fluences of 8, 10, 12, and 14 J/cm². Results showed a mean hair follicle density reduction of 62.18% to 78.29% and a mean hair follicle thickness reduction of 45% to 59%, with higher fluences achieving greater reductions. Pain and patient satisfaction surveys indicated no significant difference in comfort between high-fluence (14 J/cm²) and low-fluence (8-10 J/cm²) treatments. High-fluence treatment was found to be efficient for hair removal.
