If anyone knows how to make blue hair look chic, it’s Nicole Richie. The style maven gave her newly darkened locks a sophisticated twist at the 2014 Baby2Baby Gala over the weekend—and we reached out to her hairstylist, Gregory Russell, so you can recreate the look.

Richie, who polished things off with smoldering eye makeup, let her all-white ensemble take center stage with an elegant, low-slung bun. If you're working with colored-treated strands like the star take note: "I started on Nicole's damp hair, spraying Leonor Greyl Tonique Hydratant ($43; throughout to protect her hair health and color before the stress of a blowout,” Russell tells InStyle on how he prepped for the look. For his next step, he applied R + Co Park Avenue Blowout Balm ($28; all over Richie’s head before blow-drying her hair straight with a ceramic round brush.

Once Richie's hair was dry, Russell created a deep part on the left side of her head, adding a dab of Leonor Greyl À l'Hibiscus Styling Gel ($35; for an ultra-sleek finish. “I then pulled the hair back tight and fastened it low with a bungee tie, twisting the ponytail and wrapping into a sleek bun,” he says. Finally, a spritz of Serge Normant's Dry Oil Finishing Spray ($24; added the perfect amount of shine.RELATED: How to Get Nicole Richie’s Style, Straight from the Star Herself
