WHERE The 7th Annual Teen Vogue Young Hollywood Party in Los Angeles

THE STYLE Chunky grown-out ribbons of color in high-contrast blond
WHERE Her manager Marc Jordan's wedding to Katharina Harf in Venice
WHY WE LOVE IT "We kept saying we wanted to play around with color, but we didn't want to do anything too sweet," said her hairstylist, Ursula Stephens. She added blond extensions (yes, that's right!) through the entire top of Rihanna's head, but left the roots natural. "Why dye when you can just buy?" said Stephens.
Jordana Brewster's Beaded Headband
THE STYLE A twisty updo held in place with a bejeweled ribbon band
WHERE The 6th Annual Friends Of El Faro Event in Los Angeles
WHY WE LOVE IT "Jordana came in with this beautiful headband, and I knew I wanted to make her style glamorous, but still keep it youthful," said Byron Williams who created the look. Before putting on the band, he teased the hair around the crown, and twisted back the front sections. Then he divided the hair into three sections and pinned it up. "It was kind of like a sculpture," he said. "I just arranged the strands where they went naturally."
Amber Heard's Platinum Pompadour
THE STYLE A soaring, brushed back updo in eye-popping blond
WHERE The Zombieland premiere in Hollywood

Mary-Kate Olsen's Windswept Waves
THE STYLE Loose spirals that somehow look even prettier in the breeze

Jennifer Garner's Ropey Waves
THE STYLE Center part with loose, beachy waves starting around the ears
WHERE The premiere of The Invention of Lying in Hollywood
WHY WE LOVE IT The top looks polished and well-groomed, while the bottom strands are textured and well-defined. For a super-simple take on the look, wrap wet hair in a towel, sleep on it and resist the urge to run a brush through it in the morning. Trust us-it really works.
January Jones's Textured Chignon
THE STYLE Piecey and wavy in the front pulled into a rounded updo
WHERE The 61st Primetime Emmy Awards in Los Angeles
WHY WE LOVE IT Mark Townsend, who styled Jones's hair, was inspired by the detail of her Versace gown. "I kept the dress hanging close by as I worked," he said. Townsend blew her hair out with a round brush, and then pinned small sections artfully on the back of her head. "I purposely left some hair loose around the face to catch the light," he said.

THE STYLE Loose twists on either side of the head tucked into a messy bun
WHERE The Nanette Lepore show at New York City Fashion Week
WHY WE LOVE IT "We wanted to keep Lauren's look simple and elegant-nothing too complicated," said Christine Symonds, the stylist who created it.

"It's perfect for a girl on the go."
Audrey's Glam Cut
THE STYLE A short crop slicked back on the sides and wavy and voluminous on top
WHERE The premiere of Coco Before Chanel in New York City
WHY WE LOVE IT Audrey's hair is a study in contrasts: Puffy yet sleek, curvy and stiff but undeniably chic. For a similar glossy finish, rub lightweight gel between your palms and smooth over entire head-it has more hold and sheen than regular mousse.
Madonna's '60s Style
THE STYLE Teased hair pinned half back and rounded ends
WHERE The Marc Jacobs Fashion Show in New York City
WHY WE LOVE IT "Madonna just finished her tour and is back in New York, so we went for something polished and sophisticated," says Andy LeCompte, the stylist who created the look.

Olivia Wilde's Loose Bun
THE STYLE Wavy layers in the front and an untidy bun at the base of the neck
WHERE The Artist For Peace And Justice Kick-Off Party in Toronto
WHY WE LOVE IT The shoulder-grazing pieces in front are sweet and girlish, but Wilde's low rumpled bun keeps it from feeling too prom-ish. To try the look, twist the length of your hair partially around the base of your ponytail before pinning in place-leaving the ends loose gives the style a seductively unplanned feel.
Megan Fox's Sculpted Waves
THE STYLE A deep side part and long, perfectly coiffed waves
WHERE The Jennifer's Body screening at the Toronto International Film Festival
WHY WE LOVE IT Hairstylist Renato Campora, who created the look, was inspired by Elizabeth Taylor. "Megan has undeniable beauty, and the spirit of real movie star," he says.

After letting them cool for ten minutes and removing the pins, Campora brushed through the hair, and finished with styling wax and hairspray for hold.

THE STYLE Wavy chin-length hair-with all the long layers hidden away at the nape of the neck
WHERE The Whiteout after party in Los Angeles
WHY WE LOVE IT Beckinsale's stylist, Adir Abergel gave her a shorter style without a single snip. "I backcombed the roots at the base of the head for texture, then rolled the long hair up and pinned it with criss-crossing bobby pins," he explains. His secret for keeping the waves in front perfectly imperfect? Frederic Fekkai Magnifique Finishing Creme, $23; ulta.com
Freida Pinto's High, Messy Bun
THE STYLE A thick, loose bun piled on top of the head with tons of airy flyaways
WHERE The GQ Awards in London
WHY WE LOVE IT Not all buns are prim and proper-but especially not Freida Pinto's. To keep a high bun from looking too formal, divide a loose ponytail into a few different sections. Twist each individually, and tuck in place with bobby pins.
Rachel McAdams's Wispy Updo
THE STYLE Face-framing bangs and glamorous lift
WHERE A screening of The Time Traveler's Wife at the American Film Festival in France
WHY WE LOVE IT To dress up a simple French braid, Rachel McAdams tucked the end of the plait up and under (and off her neck) and kept her bangs stick straight. To copy her look, skip the Bumpit and backcomb the hair around your crown to give the style just a touch of volume.
Sophia Bush's Neat Chestnut Waves
THE STYLE Sleek shoulder length crop with flirty curls
WHERE At a CW party in Pasadena

THE STYLE Bright auburn, extra-long strands
WHERE New York City
WHY WE LOVE IT Eye-popping color like Ashlee Simpson-Wentz's doesn't need a complicated style to shine. For an easy-going wave, braid damp hair at night and brush with a wide-tooth comb in the morning.

Eva Mendes's Bejeweled Headband
THE STYLE A sleek ponytail with a wide Dolce & Gabbana headband
WHERE The Venice Film Festival

AnnaLynne McCord's Wild Waves
THE STYLE Tons of windblown, untidy spirals
WHERE The season 2 premiere of 90210 in Hollywood
WHY WE LOVE IT Naturally curly hair doesn't have to look frizzy or unkempt. Case and point: Annalynne's soft and seductive corkscrews. Dry with a diffuser-and be sure to use a silicone-based smoothing serum to tame strays.
Amber Valletta's Razored Bob
THE STYLE A gradually layered, above the shoulder cut
WHERE NASDAQ MarketSite closing in New York City
WHY WE LOVE IT Layered bobs can slip quickly into soccer mom territory, but this one is undeniably flattering and low maintenance. The key? Tapered layers starting below the ears to give the style depth.
Jennie Garth's Loose Spiraled Bob
THE STYLE A wavy, chin-length crop
WHERE The 36th Annual Daytime Emmy Awards in Los Angeles
WHY WE LOVE IT The neat part keeps the hair polished enough for the red carpet, but the curly waves are fun and flirty. Instead of a traditional curling iron, try a double-pronged tool for extra body.
Lush, Curvy Ends
THE STYLE Victoria's Secret model Miranda Kerr's sideswept bangs and curled ends
WHERE The launch party for VS's new Heavenly Enchanted fragrance in Los Angeles
WHY WE LOVE IT Sure, straight hair looks polished, but it can be boring at night. Pump it up by tightly wrapping just the ends of your hair around a large barrel curling iron. If you have layers, twist shorter, front pieces away from your face for a flirty kick.
THE STYLE Anne Heche's light and airy curls
WHERE In New York City on The Late Show With David Letterman
WHY WE LOVE IT Tight ringlets can be frizzy and pageanty, but these below-the-chin spirals are as soft as they are sexy. Curl only the bottom few inches of your hair for a face-framing effect.
Subtle Amber Highlights
THE STYLE Alexis Bledel's bouncy auburn layers
WHERE At Planet Hollywood to promote her new movie, Post Grad, in New York City
WHY WE LOVE IT The faint reddish highlights add light and depth to chestnut hair. To keep them from looking too harsh, ask your colorist for a hue that's only one shade from your natural color.
THE STYLE January Jones's piecey, above-the-shoulder bob
WHERE The season three premiere of AMC's Mad Men in West Hollywood
WHY WE LOVE IT The cut is just short enough to have tons of body-without taking tons of time. Add hold by working a dab of curl cream into damp hair, and then, scrunching strands in small handfuls, dry with a diffuser. A drop of silicone-based shine serum will tame any pesky flyaways.
Long, Healthy Hair
THE STYLE Courtney Cox's radiant strands
WHERE A Disney-ABC party at The Langham Hotel in Pasadena, California
WHY WE LOVE IT Most below-the-shoulder, color-treated hair looks damaged and dull. Get a seriously shiny, deeply nourished look by adding an intensive conditioning mask to your weekly routine. The oils smooth lifted cuticles and strengthen broken pieces; the result is a gorgeous, glossy finish your hair will thank you for.
Loose, Glossy Waves
THE STYLE Sienna Miller's glamorous waves and deep side part
WHERE A screening of G.I. Joe: The Rise Of Cobra in L.A.
WHY WE LOVE IT The big, undulating curls are jaw-droppingly elegant, but not too formal. Smooth along the part with styling cream for neatness and hold, and be sure the waves start just below the ears. Combing through them with a bristle brush adds extra body and shine.
Easy, Evening Ponytail
THE STYLE The Hills' Audrina Patridge's low, wavy ponytail
WHERE The Teen Choice Awards in Universal City
WHY WE LOVE IT A pretty ponytail is the fastest (and easiest) way to transform limp office hair into a flirty night look. Don't worry about shorter layers falling around your face-they add a sexy, windswept touch.
