Laser hair removal is a procedure that removes unwanted hair from the body. It involves destroying the hair follicle with a laser, which prevents new hair from growing in that place. The laser beam is aimed at the area where you want to remove hair. The beam penetrates the skin and targets the pigment in the follicle, which absorbs light energy and converts it into heat energy. The heat energy damages the follicle cells and breaks them down, preventing new hair from growing in the area.
