According to the search results, it is recommended to shave the area to be treated the day or night before your laser hair removal appointment. Shaving helps to remove hair above the skin, which can interfere with the lasers ability to target the hair follicle. However, it is important not to shave immediately before the treatment, as this can increase the risk of inflammation and swelling. It is also important not to wax or pluck the hair for at least four to six weeks before the treatment, as the laser targets the hair roots, which need to be intact.
