The hair all over our body is constantly shredding and regrowing. At any given time, the hairs on our body will be a mixture of actively growing, and hairs which are about to shed to make way from new growth, which look the same to the naked eye. Laser and IPL will only be effective on hairs which are actively growing. Because of this, with each session you will begin to notice your hair become ‘patchier’ in the treated area. Multiple sessions allow all hairs actively growing to be treated successfully.
