Before applying heat directly to her hair with a curling iron, Knight spritzed this hair spray through each section for two reasons. The first was heat protection. (It protects hair up to 410ºF.) The second was staying power without stiffness. (Remember a Brigitte Bardot look is all about volume with movement.)
From there, Knight moved on to curling her hair. "I took a 1.5-inch curling iron, pulling two-inch sections, and curled round the barrel," he says. "I curled all the hair from the top of her ears down towards her face, and all of the hair above this away from her face. Doing this is flattering, as it gives a voluminous kick to the shape."
