Keri Russel demonstrates how to pull off the softer version of the classic ballerina bun. Begin by relaxing natural curls with Karastase Curl-Relaxing Nutri-Sculpt Mousse before blowing them dry. Then recurled the hair with a half-inch iron, adding volume at the top and separating curls with Kiehl's Malleable Molding Paste. Finally, gather the hair loosely and pinned it into a French twist, setting the style with firm-hold hairspray.
