Greetings,you may can approach Laser hair reduction.Laser hair reduction is painless and also much effective as compare to other.During the procedure, a laser pulasting light beam passes throgh the skin to indivdual hair follicle and damages the follicle. Interestingly, not all hairs are actively growing at the same time ,there are three distinct phases: growth, regression, and resting,where treatments effect in the active growth phase . Since other hairs will enter this active growth phase at different times,therefore multiple session required.Regards.
