Amanda Seyfried looks ethereal here in long mermaid waves that have been pulled back with some gorgeous diamante barrettes. Large bouncy waves are added all over this long 'do to give it maximum movement and shape, which is further enhanced by subtly teasing out the waves and curls for more shape and volume. This glam, wild 'do is surprisingly easy to re-create with the right tools and needs product to tame fly-away hair. Regular trims will also help maintain a healthy look and feel by preventing split ends.
