Waxing is the most common method of hair removal in spas today. Hair on any part of the body or face can be waxed. Warm wax is applied to the area and then removed, bringing the hair with it. There are two types of wax: hard and soft. Hard wax, which is easier on delicate skin, is often used on the face, underarms, and bikini area. Soft wax is used on the legs, arms, back, and chest.
