Among waxing products, hard wax is best for hair removal in sensitive areas of the body like the bikini line, underarms, and face. Once applied, the hard wax will wrap around the hair follicles and harden as it cools. The cooled, hardened wax is then quickly removed without the need for waxing strips. Because hard wax will not adhere to the underlying skin, removal is generally less painful than soft wax alternatives. The non-stick property of hard wax also diminishes the chance of damaging the delicate skin beneath it.
