Molly Sims updo can be created on any hair that is in medium sized blond. This hairstyle will really show a dimension and shine that suits her perfect. To get her style you must first deep side part on a clean dry hair. Next make waves on the hair with the help of a waver when the hair is dry hair. It will be similar to a crimper, but instead of crimping you will be getting waves. Spray all over the waves using a flexible-hold hairspray. Pull the hair back creating a bun and a ponytail. Then twist the hair clockwise and pin the pieces using bobby pins.
