Try Beckinsale's voluminous ponytail. Mist hair with a root-lifting spray (Redken Volume Rootful 06 Root Lifting Spray is one of our favorites). Flip your head over and blow-dry with a large round brush. After hair is dry, curl the ends up to the middle with a two-inch curling iron. Tease the roots, then gather hair into a high ponytail. Conceal the elastic by wrapping a section of hair around it and securing with a bobby pin.
