Nicole Richie has got a long and tousled hairstyle which is a great way to style the hair which is long. To get her hairstyle, first part the hair down the center immediately after coming out of the shower. Next spread a wave-enhancing cream on the towel-dried hair. Then blow dry the hair with the help of a diffuser to get natural texture. After the hair becomes completely dry, mist the waves with a salt spray and scrunch them using your hands. After the hair becomes naturally straight, use a one and half inch curling iron to style your waves and complete the styling.
