Who: Kate Beckinsale
Where: "Underworld: Awakening" Madrid Photocall

Volumized waves paired with lots of luxurious shine equals red-carpet glamour.

Get her look: Apply volumizer to damp hair and blow-dry until 90 percent dry. Make a center part and using large heated rollers, wind inch-wide sections of hair around the barrel and let set. Unravel hair, rub some serum between your hands and run fingers through hair from mid-length to ends for separation and shine.

Who: Angelina Jolie
Where: "In the Land of Blood and Honey" Los Angeles Premiere

Loose wavy tresses are swept back away from the face to show off Jolie's perfect features.

Get her look: Curl hair using a curling iron. To add volume at the crown, lightly backcomb hair on top. Slip on a skinny headband, pushing all hair off the face. Mist the crown area with hairspray for hold, then remove the headband.

Who: Ashley Greene
Where: "Breaking Dawn Part 1" Los Angeles Premiere

Soft, shiny waves like Ashley Greene's look so sultry and glamorous. All you need is a final slick of lipstick -- in sexy red, of course!

Get her look: Make a center part and blow-dry hair using a flat brush. Curl hair with a small-barrel curling iron then brush it to perfection. Apply a shine lotion to create a glossy finish and use hairspray all over for hold.

Who: Kristen Stewart
Where: "Breaking Dawn Part 1" Los Angeles Premiere

Take a lead from Stewart and work plenty of mini braids into an updo for a unique twist.

Get her look: Prep hair with a texturizing product and roughly blow-dry. Take random sections and make plaits, fishtail braids and twists of varying sizes -- except at the top of hair. Backcomb the front section to add volume and pin it back at the crown. Spritz hairspray all over.
