Laser hair removal

The evolution of new technologies has helped to improve the clinical efficacy of laser hair removal and increase understanding of hair biology and phototrichoregulatory interactions. Long-term hair removal is now a realistic goal in the majority of individuals. Although the optimal schedule for repeat treatments is not known, most laser surgeons report treatments at 4- to 8-week intervals or at the first signs of regrowing hairs. Newer radiofrequency technologies might address the issue of white and light blond hair phenotypes;however, their exact role in the laser hair removal armamentarium remains to be further elucidated by future studies.
