Nicole Richie has got a loose updo which gives her a casual look and it is a perfect style for a summer. To get her style first spread a texturizing cream over the damp hair and then part it to one side. Next blow dry the hair with a diffuser and round brush to make it smooth and get volume. If the hair is frizzy or wavy smooth it using a straightening iron. Leave the bangs and piece of hair on both side and collect the rest of the hair to create a loose ponytail. Secure the ponytail with an elastic band and wrap the ends around the base to pin it in place.
