Kirsten Dunst has got a new medium sized blonde hairstyle and it is the best choice for prom and a perfect way to style a shoulder-length hair. To get her hairstyle, first part the hair to a side and apply a smoothing cream to the damp hair. Next use a round brush to blow dry the hair straight. Take a 1-inch curling iron and curl ends of the hair and also twist the barrel outward to get more flair. Separate small section of the hair or bangs from front of the face and pin it behind. If you want use a jeweled barrette to secure the hair with it.
