The term 'Hair-Removal Tool' can be summarized as a LASER, which is a five letter word. A LASER is a device that emits a beam of light at a specific wavelength, which is used for various medical and cosmetic procedures, including hair removal. Lasers are often used to remove unwanted hair from the face, legs, arms, and other areas of the body. The LASER works by targeting the pigment in the hair follicle, which causes it to break down and eventually fall out.
