According to the search results, it is recommended to shave before laser hair removal. Shaving the night before or the morning of the treatment is suggested to remove as much hair as possible so that it doesnt absorb most of the lasers energy. Shaving 24 hours before the appointment is also important to reduce the chances of burns with the hair being below the skins surface. Waxing, plucking, or any other hair removal method other than shaving is not recommended in the lead-up to the appointment because the laser needs hair present to target. However, it is crucial to wait until the skin has fully healed before shaving after the treatment to avoid any irritation or damage, which can take up to two weeks.
