Textured Coif
Tired of fighting humidity-induced frizz? Embrace your natural texture and craft Scarlett Johansson's updo. Similar to the roughed up hairstyle at the Haider Ackerman spring 2010 show, Johansson's locks were kept off the neck via pinned-up plaits.
Faux Bob With Statement Barrette
Indulge your crop-cut craving without snipping a strand: Lauren Conrad's faux bob is the ideal fix on a hot summer night. For a classic touch, add a vintage-inspired barrette on the side like Conrad did—antique hair accessories are in for summer (see Dolce & Gabbana's spring 2010 runway for inspiration).
Undone Chignon
Seemingly effortless style is always chic. For a not-too-polished do, pull some strands out of your chignon, as Olivia Wilde did. The undone look also appeared on Thakoon's spring 2010 catwalk.
High Bun
High buns were all over the spring 2010 runways—and Kate Bosworth is just one of a handful of stars who have embraced this warm-weather-ready do (see January Jones and Jessica Alba).
Face-Framing Strands
Olivia Palermo's signature hairstyle is gaining strength in numbers—Anna Kendrick, Jessica Biel, and Rachel Bilson have also recently worn center-parted updos with thick face-framing locks.
Soft Pony
A classic ponytail never goes out of style. Runway model Chanel Iman wears this clean do flawlessly.
Pony with Side-Swept Bangs
Adding side-swept fringe to a timeless midplaced ponytail can soften an angular jawline and accentuate cheekbones. Jennifer Aniston makes this easy hairstyle look red-carpet-ready.
Side Braid
The side braid is the breakout trend of summer. Zoe Saldana is one of many stars to wear this megapopular do, which first turned heads on the spring 2010 runways of Alexander Wang and Miu Miu.
Pumped-Up Chignon
Teasing hair at the crown and brushing a soft layer over it can yield winning results—just see Hilary Duff's chignon for proof. Though subtle, a bit of height at the top adds instant glamour to any look.
Slick Bun
Wet, slicked-back updos permeated the spring 2010 runways at shows like Emanuel Ungaro, Matthew Williamson, and Zac Posen. Heidi Klum took this high-fashion look to the red carpet, pulling hair into a tidy bun.
Retro Updo
Drew Barrymore has a thing for '60s dos with megavolume, and it's easy to see why with this striking SAG Awards bouffant, her most recent return to teased territory.
Pigtails
Pigtails are a prime summer hairstyle, thanks to Prada and Bora Aksu—and Alexandra Richards' soft plaits exemplify the trend.
Hair Knot
A knot is a simple yet effective way to keep hair in place—great for breezy beach days and summer music festivals. To take the do up a notch, try a braided version like Diane Kruger's.
Decorative Headband Do
Whether you opt for Yves Saint Laurent's edgy plastic or Whitney Port's sequins, a decorative headband is both practical and stylish, making it a must-have for warm summer days.
Megabun
Choosing a Lanvin dress for the London premiere of her movie The Back-up Plan, Jennifer Lopez also wore the fashion house's spring 2010 runway hairstyle. Those with a flair for the dramatic can streamline their summer silhouettes with this skyscraping do as well.
Tamed French Twist
If a mile-high bouffant à la Lopez and Barrymore isn't your style, keep the matte texture (which is sexy for summer!) but temper the pouf with an elastic headband as Amanda Seyfried did.
Bun With Blunt Bangs
Unless you're attending a fete in the Sahara, try to withstand the urge to pin bangs back: An updo with brow-grazing fringe will draw attention to your come-hither stare. Blunt bangs like Nicole Richie's send a strong, confident message—and are especially trendy for summer.
Side-Pinned Roll
Parting strands down the center and securing on the sides is sweet, but to take this do a step further gather hair into a low pony and pull locks over and under, wrapping until a messy roll is formed. Use pins to hold the shape and—voila!—you've got a summer-ready updo like Lydia Hearst's.
Side Pony
Milly by Michelle Smith's spring 2010 collection was punctuated by side ponies, which are making a major comeback. Showcasing this side-swept look just right: actress Mila Kunis.
Asymmetrical Updo
Keeping hair in place isn't always easy—but if you feel your updo falling more to one side than the other, don't sweat it: As Sandra Bullock demonstrates, a loose asymmetrical hairstyle is super-chic.
Imperfect Bouffant
Having an imperfectly shaped pouf isn't the end of the world. In fact, it may just be the beginning: At the ELLE Style Awards in London, Alexa Chung's downtown-cool vibe was accentuated by a textured, slightly lopsided bouffant.
