Get the look: For a loosely textured style like Aniston's, have long layers cut into your hair (a cut like hers works well on fine, straight or wavy hair types). Style with a blow-dryer and round brush to emphasize the layers or tousle with your hands while blow drying for a more disheveled look.

Scarlett Johansson
Get the look: For touchable waves like Johansson's use a curling iron to recreate this look by wrapping large sections of hair around the curling iron, not clamping it in the curling iron for looser curls. Run your fingers through hair once it's cool for a more wavy finish.
