You may have heard of negative ion dryers, able to break down water molecules so your hair can absorb them, resulting in super-moisturized locks. The 1875-watt Vidal Sassoon Variable Ion Dryer takes this technology one step further with its ion select dial, which adjusts to treat your individual hair type. Turn the dial low to give fine hair delicate shine and moisture, or set it on high to condition thick or coarse tresses. Gold with black accents.
