Olivia Wilde has got a new brunette updo along with bangs which is a sophisticated way to style the hair very fast. This hairstyle can look perfect for those with medium length hair. To get her hairstyle, first you must apply a styling cream onto the dry hair and then comb the hair up to create a high bun. Secure the bun with the help of elastic. Next take a flat iron and straighten the bangs. Then sweep the bangs to the side using a little amount of gel. At last mist all over the hair with an anti-frizz hairspray to stop any flyaways.
