Hair color, growth and density are factors that will play into your results. You can expect to see a gradual decrease in hair thickness and growth and an overall reduction in hair. This treatment will only target hair that is in the active stage of growth; therefore, multiple treatments are usually required. We recommend a minimum of 3 treatment with up to 6 or 8 for optimal results. Occasional touch-ups are usually necessary as there is no truly permanent hair removal process.
