For touchable waves, start with a volumizing spray or powder, says hairstylist Juan Carlos, who has worked with Jennifer Lopez. Loosely gather hair into two low ponytails, and secure with rubber bands. Twist each pony around its base; pin and leave in for two hours. Shake out and voilà—goddess bed head. Create waves on shorter dos by wrapping strands vertically around a 1-inch curling iron; begin at the top of your ears and continue down to the ends.
