He divided dry hair into two sections, curling the bottom layer with a 1-1/2 inch iron for volume, and teasing the roots of the top section with a fine tooth comb. He swept it back, securing in place at the crown of the head and finished with a blast of sheer hold hairspray. 02 of 17 Kristin Davis's Softly Sculpted Waves Michael Caulfield/Getty Images THE STYLE A side part and smooth, shapely spirals WHERE The 13th Annual Costume Designer Awards in Beverly Hills INSIDE SCOOP "We decided on this look because it suits Kristin Davis's classic style, channels a bit of Rita Hayworth-and flatters the grandeur of her dress," said hairstylist Marcus Francis, who created the look. He dosed the roots with a volumizer and worked a dollop of mousse through wet strands before blowing drying and setting the entire head in chunky pin curls. "I brushed out the hair after five minutes and set it again," Francis explains. "I wanted it to bounce and move throughout the night for Kristin."

"I softened the ends with a medium-sized curling iron and finished with a blast of light hold hairspray."

If graduated, face-framing layers are feeling a bit dated, advise your hairstylist to go for a series of long, one-length layers throughout. It's a fresh look with subtle impact.

The slightly off-center embellishment has a playful appeal. 07 of 17 Emma Watson's Polished Pixie Daniel Deme / WENN.com THE STYLE A sleek, side parted pixie that's combed flat WHERE The ELLE Style Awards in London WHY WE LOVE IT Emma Watson debuted her short crop late in 2010, and now she's learning to style it in a variety of ways. Here, the drenched, shower-wet finish is imminently sexy; the crisp part and combed-through texture feel entirely pulled together. Try on Emma Watson's pixie crop now! 08 of 17 Gwyneth Paltrow's Wavy Layers Arnold Turner/WireImage THE STYLE A polished center part and gently waved layers WHERE The 53rd Annual Grammy Awards in Los Angeles INSIDE SCOOP Couture Colour hairstylist David Babaii calls Gwyneth Paltrow's look "wild bohemian." Starting with clean, damp hair, Babaii dosed Paltrow's strands with an oil treatment before rough-drying it for texture and shine. He wrapped random sections around a one-inch curling iron, taking care to only clip the center of the strands, leaving the roots and ends free. "That's how you create that uneven wave pattern," he explained. To finish, he ran his fingers through the waves to loosen up too-tight spirals.

But it was her soft but structured updo that completed the look. One part Old Hollywood glamour, one part modern It Girl, and 100 percent gorgeous. 11 of 17 Nicole Kidman's Long, Loose Layers Stephen Lovekin/Getty Images THE STYLE Below-the-chest strands with subtle, easy layers WHERE The Just Go With It premiere in New York City WHY WE LOVE IT A hairstyle doesn't have to be overworked to be downright gorgeous.

Try on Hayden Panettiere's many cute hairstyles now! 13 of 17 Kim Kardashian's Skinny Headband Alexandra Wyman/WireImage THE STYLE A thin, nude headband topping off a high, messy updo WHERE Launching her jewelery collection Belle Noel in West Hollywood WHY WE LOVE IT There's just something romantic about a skinny headband, especially if you're Kim Kardashian and it's holding back a riotous mane of hair. The contrast of the headband's peachy tone against her deep espresso hair adds just the right amount of definition. 14 of 17 Jennifer Lopez's Voluminous Mane Kevin Mazur/WireImage for Gillette Venus THE STYLE Long, blown-out strands with tons of lift WHERE A Gilette Venus event in New York City WHAT SHE SAID "There's two different ways I feel very beautiful and sexy," Jennifer Lopez told us at the event. "This first is a long big mane, like this. I'm a Leo, so I need my mane. But I also love the opposite, which is my hair pulled really tight and off my face. That probably represents the two sides of me." 15 of 17 Minka Kelly's Soft Layers Michael N. Todaro/FilmMagic THE STYLE Long gradual layers with subtle bend at the ends WHERE A NYLON magazine party in New York City WHY WE LOVE IT Minka Kelly's touchable style, created by Mark Townsend, reminded us of a simple truth: No matter how good your haircut is, if your hair isn't styled well, no one will know. If you've got long layers-and most of us do-rather than blowing them out pin-straight, take a few extra minutes to add a slight curl on the ends. It flatters your face and gives a simple style welcome movement. 16 of 17 Gillian Jacobs's Brushed-Out Curls Jordan Strauss/WireImage THE STYLE Loose, combed-through curls swept back from the forehead WHERE The Entertainment Weekly 2011 Pre-SAG Party in Los Angeles WHY WE LOVE IT Community star Gillian Jacobs and her hairstylist Marcus Francis reminded us of a simple way to boost volume: Rather than parting your hair, push it straight back. Volume icons like Veruschka and Brigitte Bardot kept this trick near and dear-try it the next time your strands fall a bit flat. (A blast of hairspray will help your hair stay put.) 17 of 17 Dianna Agron's Knotty Bun AXELLE/BAUER-GRIFFIN.COM THE STYLE A low, messy twist and graphic, sideswept bangs WHERE The 17th Annual Screen Actors Guild Awards INSIDE SCOOP "For Dianna Agron's look, we merged vintage and modern by doing a double knot in the back and sweeping the bangs to one side. That way, you get a glimpse of the effortlessly undone 'do from every angle," said Suave Professionals hairstylist Jenny Cho. To literally knot Agron's strands, Cho split the hair down the center in two sections. "Tie the two sections like you're tying a bow and secure with pins. Then make another knot right under the first, and secure with more pins. Leave the ends out to give it the undone finish," she advises.
