Stylists at Sally Hershberger LA dish on how devotee Ashley Greene maintains her red-carpet-worthy tresses:

The Cut

After wrapping "Twilight: Eclipse," Ashley decided to grow her hair out and so, in the meantime, stylist Louise Moon gave her instant length with (human hair) extensions that matched her natural texture. Next, her colleague, Guy Riggio, cut the extensions to blend into Ashley's real hair and created a face frame to give her versatility during daily styling and red carpet events. “I wanted a look that could be both elegant and sexy. The finished product is a very chic look that will give her many options during the rest of her 'growing out' phase.”

The Color
Star colorist Negin Zand finished Ashley’s look by giving her a light golden brown base and highlights that are a mix of baby blonde and golden tones. An ideal combination for Ashley's coloring, and for spring/summer.

Celebrity stylist Adir Abergel shares how he created Kristen's '50s-inspired updo for Thursday's "Twilight" premiere:

"I started by applying the Fekkai Full Blown Volume Styling Whip at the roots and throughout the hair. Using a round brush, I blow-dried the hair away from the face, and placed it in pin curls. I then allowed the hair to cool before removing the curls. Next, I styled the hair by hand raking the it into a side pompadour, securing with pins. To shape the face, I pulled a few pieces in front then secured the look with Fekkai Coiff Sheer Hold Hairspray."

Recreate the "Twilight" star's latest look with this step-by-step guide, courtesy of celebrity makeup artist Vanessa Scali:

“We wanted to create a soft, glowing goddess look to complement her beautiful Alexis Mabille Couture dress. The overall look was golden skin, soft blushed cheeks, champagne shimmer and a softly lined eye.

First, I prepped Ashley’s skin by applying Mark Primed for Perfection Face Primer all over the face to create a nice, even canvas. I like the skin to look flawless but real, so I always use foundation and concealers sparingly. With Ashley, I used Mark Speedway Do Everything Makeup in Natural. I applied it with a foundation brush and then blended it with my fingers. Using my fingers to blend heats the product just a bit and leaves a seamless finish. Next, I applied Mark Good Riddance Hook Up Concealer in Light/Medium under her eyes.

I wanted to create a nice luminous glow, so I applied just a touch of Mark Get Bright Hook Up Highlighter in Natural to the top of Ashley's cheekbones, down the center of her nose and the bow of her top lip. Next, I applied Mark Bronze Pro Bronzing Powder in Pro Glo to her temples, under her cheekbones and under her jaw line to lightly enhance the bronze in her natural skin tone. Lastly, I used mark Just Pinched Instant Blush Tint in Peachy on the apples of her cheeks for the perfect healthy flush.

For Ashley’s eyes I started by using mark I-mark Custom Pick Eyeshadow in Nomadic to create a champagne shimmer all over her eyelids and under the bottom lashes. Next, to define and elongate the lash line, I lined her upper eyelids with mark Keep It Going Longwear Eyeliner and Shadow in Entourage (Black Shade). For a touch of added depth, I used Mark Get in Line Hook Up Waterproof Eyeliner in Painted Black at the very base of her lashes. I finished with a few generous coats of Mark Lash Splash Hook Up Waterproof Mascara in Black.

Finally, for Ashley’s lips, I started by using a dab of Mark Kiss Dry Goodbye Lip Smoother to give her lips a touch of moisture. I then used mark Kissink Liptint Marker in Berry to define the outer edge of her lips and smudged the color into the center."

It's so refreshing to see Kristen Stewart in a soft, age-appropriate hairstyle. I'm loving this side-swept ponytail on the "Twilight: Eclipse" star— it works well with her face shape, and shifts focus to her striking azure eyes.
