Waxing is an excellent way to deal with most hair removal. Waxing leaves the area smoother than shaving does, because it pulls the hair out from below the top layer of skin. This is the easiest and most convenient way to go about removing hair form large areas.
With the hot waxing the thin layer of heated wax is applied to the skin in the direction of the hair grow. The hair becomes embedded in the wax as it cools. The wax is than pulled off in the opposite direction of the hair grow, taking the hair with it.
Cold waxes work similarly. Strips are pre-coated with wax and pressed onto the skin in the direction of the hair growth and pulled off in the opposite direction.
