Long layered hair may take a little extra time to style, but the  beautiful result is more than worth it. Make sure to get a trim every  six weeks or so to ensure that your hair looks its healthiest and layers  appear top notch. Long layers look great when curled with a one-inch  barrel curling iron. For extra volume, use two-inch curlers while hair  is damp and don't take them out until hair is completely dry.
