“I have been familiar with Revlon for as long as I can remember. I vividly recall my mom wearing Revlon makeup and I remember getting to the age when I was finally able to wear Revlon myself," says Emma Stone of the brand she's now representing.

“I have always admired Revlon and their commitment to giving women the confidence and tools they need to feel beautiful, both inside and out,” adds fellow Global Brand Ambassador Olivia Wilde. "It's exciting to join a company with a big heart and big ideas!”

The talent behind Emma Stone's Met Gala hair and makeup share how to achieve "The Amazing Spiderman" star's striking beauty look:

The Hair: "Undone" Chignon

Celebrity stylist Mara Rosznak explains: "I wanted to balance Emma’s dress, which had a beautiful maturity to it, with hair that felt modern and soft.

To recreate this style, first apply Kérastase Mousse Volumactive all over towel-dried hair, along with Kérastase Spray Volumactive at the roots for extra volume.

Next, part hair to the side and rough dry the hair for a natural wavy texture. Gently pull hair back into a low messy chignon and pin in place, criss-crossing the pins as they go in.

Finally, let a few pieces fall down around the face for a soft whimsical look and finish the look by spraying hair with Kérastase Double Force Hairspray."

The Makeup: Look-At-Me Lip

Celebrity makeup artist Rachel Goodwin explains: “Emma's Met Ball makeup was inspired by the graphic black and white floral print of her dress. The lack of color prompted me to bring elements of a colorful spring garden into the makeup look opting for bold, feminine color on her lips, eyes and cheeks for a fresh youthful statement.

On her skin, I used CHANEL Vitalumière Aqua Ultra-Light Skin Perfecting Makeup SPF 15 in Beige Rosé-Pastel. This lightweight, luminous formula allowed me to perfectly even out her skin while still letting her gorgeous freckles to show. I'm obsessed with her freckles!

On her eyes, I used a wash of pale pink shimmer from CHANEL Quadra Eyeshadow in Lilium on the entire lid; then I boosted her lash line with two coats of CHANEL Inimitable Intense Mascara in Noir after placing Ardel individual lashes to the end of her eyes only. I finished by lining her inner eyelid with CHANEL Intense Eye Pencil in Clair for a subtle contrast.”

Five quick and easy ways to keep your color "first-day" fresh:

Hold Out
Though your locks may look and feel renewed, coloring can take a toll on even the healthiest of hair. To avoid breakage and moisture loss, avoid cleansing again for at least 48 hours after your initial rinse.

Opt for a Color-Depositing Cleanser & Conditioner
Winter weather can dull your newly tinted tresses in a matter of days, so stock-up on a hue-enhancing duo — like Bb's low pH, extra-mild formulas ($22 each, BumbleandBumble.com) — to extend the life of your color.

Add SPF to the Mix
SPF is a must 24/7/365, so amp up your daily conditioner with a tablespoon of your favorite lightweight SPF (per bottle; face or body).

Laminate Your Locks
A weekly intensive treatment — like Kelly van Gogh's Rich & Delicious ($48, KellyVanGogh.com) — will help rebuild, restore and protect your hair against everything from caustic water to environmental pollutants.

Seal Each Strand
Protect your color before using heated styling tools with a thermal guard formulated for your specific hair type.

The stars of "The House Bunny" attended a special CosmoGIRL screening of their new film at The Hearst Tower in New York City on Tuesday night, with each actress showcasing a different 'do.

Emma Stone was vibrant in red, Rumer Willis went for a more dark and mysterious look, while Anna Faris opted for bold blonde bangs and Katharine McPhee wore her hair in a romantic updo.

I'm partial to Emma's classic side-part and rich color, but whose hair do you think deserves the Most Beautiful Bunny title?
