So the bob has made a comeback for 2011. For those who want or already have a bob haircut the main problem that most people have is how to style it. As shown below the waved bob hairstyle is one of the on-trend ways to style a longer bob in 2011 with Keira Knightley and Alexa Chung being big fans of this years trend. This can be achieved with the help of either rollers, tongs or simply using your straighteners. A good hairspray will help hold this style but make sure you stick to waves rather than curls.
