The percentage of hairs removed per session varies in different parts of the body, with areas of thin skin (e.g. bikini and armpits) generally showing a better response than areas of thick skin (e.g. back and chin). Approximately a 15-25% reduction in hair growth can be expected with each treatment. Treatments are repeated every four to eight weeks and our laser-certified aesthetician will let you know when your next treatment will be. The hair that re-grows tends to be lighter and finer in texture. Usually, after the first treatment, you will notice a marked difference in the thickness and density of the hair that regrows.
