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.”

Recreate the "Scream 4" star's latest look with this step-by-step guide, courtesy of celebrity stylist Giannandrea:

“My inspiration for Anna’s hair was Grace Kelly rock chic. It was quite simple, but she felt very cool and beautiful.

I started by applying Kerastase Volume Active Mousse to wet hair, all over the head, roots and length. I then dried the whole head with just warm air - no brushing - just using my hands from side to side, back and forth, down and up all around, in order to keep a natural feel and build volume at the roots. Next I brushed the hair with a Mason Pearson brush and used Klorane Dry Shampoo Powder all over just to add some dry texture.

I began to pull the hair back gently on the side and very soft at the top as I wanted it to look natural in a way that wasn't too constructed, almost as if she did it herself. I then began to twist the hair in the back into a soft messy bun. I use straight pins and twist each pin on to the sides, back and all around the head in order to create a clean visual texture. A bit of messiness and a few flyways are ok. I finished the look with Framesi Hair Spray.”

Dianna Agron turned heads in a fresh, feminine take on the '50s rockabilly style at Sunday's Grammy Awards.

Below, celebrity stylist Adir Abergel shares the steps he took to achieve the look:

"I started by applying Fekkai Coiff Strong Hold Volume Mousse to the roots (on dry hair) and Fekkai Advanced Silky Straight Ironless Smooth Finish Serum at the ends. Then, I blow-dried the hair, using my hands, until it was completely dry.

Using 1 1/4" curling iron, I then curled the hair and pinned it in place starting at hairline all the way to the crown. Next, I pulled the back of the hair into a sleek chignon at the crown of the head.

To finish the look, I took the pin curls out and backcombed the roots, in order to add volume for the pompadour effect. To keep the backcombing in place, I sprayed Fekkai Coiff Sheer Hold Hairspray at the roots. Next, I smoothed the top of hair into place. Finally, I applyed Fekkai Coiff Nonchalant Piecing & Forming Wax on the ends of Dianna's hair to create some separation, then sprayed Fekkai Coiff Sheer Hold Hairspray to set."
