Emma Stone had the perfect makeup and updo at the Oscars: tasteful and chic, but still young and a little different. For the hair, celebrity stylist Mara Roszak got inspired by the blousy bow on Emma's red Giambattista Valli gown. "The bow on the dress reminded me of a flower," Roszak says, "and the bun in the back went from ear to ear to look like a flower with a loose and fresh feel." To create the style, Roszak began by using Couture Colour Pequi Oil Treatment on wet hair from ends up.

Once Emma's hair was blow-dried, Roszak added a simple part in the front. Then, to form Emma's piled-on bun, she pulled her hair into a midheight ponytail, began wrapping pieces of hair loose and wide, and secured each piece with bobby pins. Roszak topped the look off with Couture Colour Pequi Oil Finishing Polish.
