It's that time of day again! Help us pick a winner in this StyleBistro Awards category—best celebrity hair. Scroll through to see which celebrity tresses are your favorite and vote below! We'll announce the winners August 21.
Kate Middleton: Kate isn't a style sensation just because of her clothes—the Duchess' perfectly-waved chestnut locks are seriously enviable. Whether she's rocking a slight flip, brilliantly blown-out bouncy curls, or a refined updo, we know that ever since she stepped into the spotlight, we've been growing out our layers too.
Kim Kardashian: The reality queen loves sleek hairstyles. Day-to-day, Kim will often wear a gelled ponytail or a large top-knot. Ever since Kanye came into the picture, though, Kim's cut her long layers and has been leaving her hair side-swept and down. Keep it up Kimmy!
Michelle Williams: Michelle is totally the pixie princess of Hollywood. Does anyone even remember her long hair? We don't! And that's probably because the close-cut completely shows off her adorable face. The only thing that ever seems to change is the shade of blonde she's sporting on the red carpet.
Alexa Chung: Alexa's hair is so iconic, it's become a star in its own right. With that effortlessly amazing wave no one can ever replicate and the perfect shoulder-length (even an on-trend ombre!) Alexa's 'do is a definite do.
Jennifer Lawrence: If there was a Hunger Games for hair, Jlaw could give her famous character, Katniss Everdeen, a run for her money. Often, we'll spot her wearing loose waves or a messy updo with bangs. Once in awhile she even likes to show off her shimmering blonde hue with a straight style.
Alicia Keys: This singer-songwriter loves a unique updo, like the big braided one above, center. Lately she's been sculpting her once very-curly tresses into silky layers and soft waves. No matter what look she chooses, she's a total glamour-girl in our book.
Dianna Agron: The Glee star won a place in our hearts after she sported a series of beautifully braided and loose updos on the red carpet. Not only does she rock the romantic look more than most, she's perfected the tricky shoulder-length bob we're so often scared to try. We can't wait to see what type of haircut the actress gets next!
Jessica Chastain: The Help actress brought some serious respect to redheads the second she hit the Hollywood. Another one for romance, Jessica loves her free-flowing layers and half-up half-down 'dos.
Jennifer Lopez: Like Kim K, JLo loves a good top-knot. When her hair isn't securely fastened up top, Jennifer lets her long layers lay low in unkempt kinks or barely-there waves.
Amanda Seyfried: Blonde bombshell much? The most noticeable thing about Amanda's hair is, by far, its color and shine. Although, we definitely don't mind her thick barrel curls, perfectly flipped ends, or that fierce fishtail she rocked earlier this year either.
Eva Longoria: Eva's silky-smooth locks are never without shine or shape. Even when she puts it up in a high-pony, the actress' hair bursts with volume. Usually, she leaves it down in long layers for all to admire.
Sofia Vergara: She may be hilarious on the set of Modern Family, but this actress is not joking around when it comes to her hair. Like many other celebs, the star prefers her locks long and layered—in that perfect place between curly and straight. Sometimes she will surprise everyone with a strikingly straight look. Either way, she always looks gorgeous.
Lauren Conrad: LC also loves herself some long layers, but this reality-star-turned-author can be a total bunhead sometimes. We love it when her hairstyle falls casually to the side of her face—it looks romantic and way more mature than her bleached blonde Laguna days.
Now it's your turn—ready, set, vote!
