MESSY SIDE-BRAID
Boho-chic fashionista Nicole Richie rocks a messy side-braid effortlessly. The plaited do from the Miu Miu and Alexander Wang spring runways has also been worn by Rachel McAdams and Kate Bosworth.
STRAIGHT HAIR
Beach waves are always fun for summer, but as the spring and fall catwalks proved, straight strands like Reese Witherspoon's are back. Just be sure to soften flatironed tresses by adding a touch of volume and/or wispy bangs to avoid an overly harsh look.
BALLERINA BUN
As Rachel McAdams demonstrates, a ballerina bun is ideal for showing off shoulders and statement earrings. The classic updo experienced a resurgence on the spring runways, where legendary dancer Martha Graham served as inspiration at Marc Jacobs and Zac Posen.
ASYMMETRICAL SHOULDER-LENGTH DO
The grown-out-bob is in—but Anne Hathaway is the only actress with this style who had a bob to begin with! Emily Blunt and Kate Beckinsale (shown at left) got their long locks specially cut and coiffed to appear this way.
WAVY BOB
For a carefree summer do, above-the-shoulder waves are the way to go. Both Zoe Saldana (shown at left) and Jessica Alba have recently trimmed their tresses to sport this tousled style.
HIGH BUN
Lanvin's spring 2010 show made high buns chic—and Jessica Alba is just one of a handful of stars who have embraced this warm-weather-ready do (see Whitney Port, January Jones, and Kate Bosworth, to name a few).
BLACK HEADBAND
For hot summer evenings, pairing a black headband with an updo is both practical—and stylish. Whether you opt for Yves Saint Laurent's plastic or January Jones' ribbon, black adds instant glamour.
PIXIE CUT
While faux pixies reigned on Giorgio Armani's spring 2010 runway, It Girl Carey Mulligan and her Twiggy-esque do have been ruling the red carpet.
SIDE PONY
Milly by Michelle Smith's spring 2010 punk-meets-prep collection was punctuated by girly side-ponies. Showcasing this sideswept look just right: reality-TV star turned author Lauren Conrad.
MATTE TRESSES
Top runway hairstylists say matte hair is in, and it must be—trendsetter Ashley Olsen recently flaunted the high-fashion finish at an event. Even more telling: Hair industry giant Redken launched several products designed to achieve this nonshiny, velvety-smooth texture.
TEXTURED CHIGNON
Simple yet sophisticated updos are a great choice for summer; to keep a chignon from appearing overdone, rough up hair around the crown à la Victoria Beckham.
VINTAGE-INSPIRED ACCESSORIES
Intricate, antiquelike accessories shined on the spring 2010 runways; while Chanel and Dolce & Gabbana featured refined hair combs (in silver and gold, respectively), Diane von Furstenberg displayed delicate clips resembling butterflies. Mischa Barton's golden wreath is a summery example of how these runway looks can translate to everyday.
FACE-FRAMING STRANDS
If a few pieces of hair stray from your low-pony don't fret—as Jessica Biel reveals, face-framing strands can be ultrafashionable.
LOOSE UPDO
Whether clipped, pinned, or fastened, a superloose updo like Taylor Swift's is en vogue. And don't worry about it looking picture-perfect—this style looks best when slightly asymmetrical.
DEEP SIDE PART
Though middle parts are traditionally thought to be more bohemian and summery, the deep side parts from the Dior and Valentino catwalks are sexier—and more appropriate for sizzling summer nights out. A side part can also accentuate cheekbones and slim the face. To wear this flattering part by day, pinning strands to the side (as actress Michelle Trachtenberg did) is a stylish and fuss-free option.
