During The Secret Life of the American Teenager’s long hiatus, we’ve been spending a lot of time looking at photos of star Shailene Woodley. Throughout the show’s five seasons, her style has changed the most, and on the red carpet, she’s always dressed to impress.

But her outfits aren’t always the centerpiece of her look — sometimes it’s her hair!

Shai usually has her hair straightened or up in a ponytail, but occasionally, she switches it up with loose waves or a gorgeous updo.

At the BAFTA Los Angeles 18th Annual Awards Season Tea Party on Jan. 14, 2012, our favorite Secret Lifer rocked loose, natural waves, complementing her modern, abstract-patterned Jason Wu Pre-Fall 2012 sleeveless dress. Although the pleated skirt and her black Chloé Metallic Scalloped Ballerina Flats were great, we’re mostly obsessed with her hairstyle!

On the flip side, Shailene went with an updo at the 84th Annual Academy Awards on Feb. 26, 2012. It was simple, but elegant — just like her off-white Valentino Haute Couture Spring 2012 long-sleeve gown! With her hair up and dazzling eye makeup, she looked flawless, and we were also able to see her gorgeous earrings.

While Shai always looks great, is she hotter with her hair down or her hair up? Vote below!
