The treatment removes the hair at the root, which is why the hair-free result typically lasts around 4 weeks before the hair has grown back. Initially, some people may experience feeling or seeing hair in the treated area a few weeks after the wax treatment. This is because the hairs on the body are in different growth cycles. The hairs you can see in the first 1-3 weeks after treatment have been just below the skin's surface when the treatment was carried out. Therefore, you can advantageously treat approx. every 3 weeks when you start waxing with pearl wax.
