Over the weekend at the Cannes Film Festival, French Vogue editor Carine Roitfeld arrived at the Dolce and Gabbana party with thick, dark eyebrows that contrasted with her fair hair. It's obvious by her roots that she's not a natural blonde, and she isn't one to take a high-maintenance look anyway. But most colorists, while lifting a woman's base color, would lighten her brows as well to create uniformity. What do you think of this look? When you change your hair color, do you change your brow color, too?
