Most areas require 3-6 treatments. However, the number of treatments required for optimal long-term benefits depends on multiple factors, such as the size of the targeted area and the thickness, color and growth cycle of the hair itself. Each hair grows at a different rate and goes through three distinct phases: growth, regression and resting. IPL treatments work by disabling the hair that is principally in the active growth phase at the time of treatment. Since other hairs will enter this active growth phase at different times, additional treatments may be necessary to disable all of the hair follicles in a given area. During your consultation, we will be sure to evaluate all factors and outline the most effective treatment plan to attain optimal results.
