Britney Spears wavy hairstyle gives really soft and romantic look for any occasion. To get her hairstyle, first you have to part the hair down the center and then apply a volumizing mousse to the damp hair. Next blow dry the hair straight with a round brush and make sure to lift hair at the roots to get more volume when you are blow drying. After the hair gets dry, divide it into 2-inch sections and wrap both the section around a 1 1/2-inch curling iron for loose waves. Finally finger comb the hair to separate them and apply a little amount of styling cream on the palms and run them on hair to control flyaways.
