Diane Kruger’s sophisticated side-swept hairstyle for the Chanel Bijoux de Diamant 80th anniversary party this week proved once again why she’s such a red carpet master. Lucky for us, celebrity hairstylist Thomas Dunkin gave us the inside scoop on how he created her coif. “Wash hair thoroughly, and apply Sebastian Professional Stylixir to the lengths of towel-dried hair,” he told InStyle.com. “Using a round brush, blow dry the hair straight.” To hold the style, Dunkin suggests tightly twisting hair left of the part and securing with two bobby pins. Bring the rest of the hair over your right shoulder and finish the look by applying Sebastian Professional Shine Crafter Wax to strand’s shafts for a glossy finish.
