Earlier this week, model and actress Rosie Huntington-Whiteley announced her latest project as the celeb ambassador for Moroccanoil's "Inspired by Women" campaign. Huntington-Whiteley sported a fresh haircut and undone waves at the launch of the video series (directed by Bryce Dallas Howard), following six women, celebrating their encouraging stories.

Crediting Moroccanoil for her impossibly shiny hair, Huntington-Whiteley has already mastered the season's cool, wind-blown hairstyle we spotted all over the runway for fall.

To get the look at home, prep hair with Moroccanoil Treatment before blow drying to add shine and texture to the hair. Once dry, run a curling iron through large sections of hair, creating loose waves. Use your fingers to separate the waves, and set with Moroccanoil Luminous Hairspray.

At last night's Teen Choice Awards, "The Vampire Diaries" star Nina Dobrev took our favorite summer hairstyle -- the messy braid -- and made it even better.

To get the look, hairstylist Riawna Capri sprayed KMS California Freeshape Quick Blow Dry, $19.99, on Dobrev's hair before blowing dry. She then spritzed in KMS California Freeshape 2-in-1 Styling and Finishing Spray, $19.99, before creating beachy waves with a 1-inch curling iron. For added texture, Capri had Dobrev flip her hair over before spraying in KMS California Hairplay Playable Texture, $19.99.

For the braid, Capri separated the hair into three sections, twisting them clockwise, and then braided counter clockwise for more texture. To give it a more undone look, Capri pulled the braid apart with her fingers and let some loose pieces fall to frame Dobrev's face before spraying with KMS California Hairstay Medium Hold Hairspray, $17.99, to lock it in place.

Actress Zoe Kazan opted for a more casual, fun look at last night's New York City premiere of the romantic comedy, "What If." A girl after our own hearts, Kazan decided to forgo an elaborate dress and skyscraper heels in favor of a leather skirt and sneakers -- keeping the focus on her bold red lip color.

Makeup artist Gita Bass worked with Kazan and used Nars Audacious Lipstick in Lana. Dewy skin, full brows and oversized lashes completed the look.

The "Orange Is The New Black" star might have limited options when making her own cosmetics behind bars as Dayanara "Daya" Diaz, but in real life, Dascha Polanco took to Instagram to show us her beauty look of the day.

Polanco opted for a neutral summer look, pairing bronzed skin with soft brown shadows and the perfect matching nude lip with Rimmel London Show Off Lip Lacquer in Nude Eclipse, $5.99.

Diane Kruger always looks impossibly polished, but she took it to a new level of cool last night. At the second season premiere of the FX show "The Bridge," Kruger switched out her usual sleek waves for a braid we've been analyzing all morning.

Paired with a Mary Katrantzou x Swarovski multicolor embellished dress, the double French braid added to the edgy vibe. It may look crazy complicated to recreate, but you're really just making two braids -- and the second one is messy.

To get the look, divide hair into three vertical sections, and create a tight French braid down the center section. Once you've secured the ends with an elastic, take the side sections, and create a loose French braid over the center braid. Then, use a hair tie to join the braids at the bottom. It doesn't have to be perfect (or exactly like Kruger's) -- that's what makes it cool.
