Julia Roberts: Best Highlights
Blonde streaks just at the ends (not root to tip) give Roberts's beachy waves a sun-kissed look.
Solange Knowles: Best Natural Hair
Knowles embraces her natural curls, combing them up, up, and away for ample volume, bounce, and shine.
Marion Cotillard: Best Pompadour
Cotillard's pompadour has just the right amount of texture and poufiness to look young, fresh, and decidedly un-Snooki
Michelle Williams: Best Pixie
Side-swept fringe makes Williams's pixie look even sweeter.
Kim Kardashian: Best Bangs
Blunt, brow-length bangs call attention to Kardashian's eyes—and her ponytail looks sleek and formal, not athletic.
Drew Barrymore: Best Roots
On Barrymore, a few flyaways and intentionally dark roots look rock-and-roll, not rolled-out-of-bed.
Penélope Cruz: Best Chignon
Anchored slightly to the left, Cruz's braided chignon looks less severe than a ballerina-style bun, and is more easily captured on film. (Remember that for the next night out with your camera-happy friend.)
Nicole Richie: Best Center Part
Richie's center part is unfussy in a way that perfectly complements her asymmetrical ponytail's air-dried appearance
Taylor Swift: Best Throwback
Swift channels a 1920s starlet with glossy finger waves and her long hair pinned underneath into a faux bob.
Diane Kruger: Best Accessory
Hair accessories can sometimes look costumey or childish, but Kruger's elegant leaf adds the perfect finishing touch to a soft updo.
Blake Lively: Best Half-Ponytail
Lively's lightly teased half-ponytail has great volume—and her humdrum hair elastic is cleverly hidden by a loop of hair pinned around the base.
