Stars' updos bump up the volume

Cougar Town's Busy Phillips wears her blond locks in a shiny, tidy 'do. The simple style allows her to pull off full cat-eye liner, chandelier earrings and a dotty top.

Ana Ortiz, who rose to fame on Ugly Betty, shows how this volume-on-top style can work with a formal, red-carpet ensemble.

Fresh-faced Switched at Birth star Katie Leclerc wears her strawberry-blond hair in the new style—with a few strands pulled free at her temples, softening the effect.

Lizzy Caplan, star of the just-out Bachelorette, tries a more edgy take on the trend with a demi-pompadour hairstyle.

Chestnut-haired beauty Olivia Munn counterbalances a boldly graphic neckline with a smoothly sophisticated updo.

Disney cutie Bailee Madison—just 12—demonstrates that this sleek style is appropriate for beauties of all ages.

Pop singer Natasha Bedingfield rocks the look with a classic red lip and smoky eyes. The slight volume at her crown keeps the style from being too severe.

With minimal makeup and no jewelry, Anna Friel (known for her role in Pushing Daisies) shows how elegant this clean-lined 'do can be.

Zoe Saldana makes the 'do her own by wearing it with serious height at the crown and loose waves in back.
