Get the look: Apply a texturizing product (try ghd Sea Spray, $24) and roughly blow-dry your hair to add texture to it. Tease the crown of your head then secure hair into a mid-height ponytail. Tease hair in the ponytail for added texture. Pull out face-framing sections of hair and use a flatiron to straighten them, creating a slight bend at the ends.

Drew Barrymore
Get the look: To get a full pony like Drew's, add a clip-in hair extension (see how to use them here). Blow-dry hair straight then secure into a high pony and clip on the ponytail extension. Take a large section of hair and wrap it around the hair elastic to cover it and pin into place. Curl the ends of the pony (only if you use human hair extensions) with a curling iron.

Jennifer Aniston
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.
