Some people have probably been shaving since before they had a reason to. Shaving unwanted hair can give you an instant result, but only for a few hours. The hair roots remain under the skin and in a day, or in some cases hours, the hair begins to come out again. When you wax or sugar a particular region repeatedly, over time the hair growth reduces. This is because the hair follicles in the area gets damaged, so the hair that comes out is less healthy and comparatively thinner because it’s roots are weakened. Staying consistent with your waxing (& no shaving in between) will help you achieve the best results.
