"If you're going for the romantic waves, blow dry the hair straight and spray it with a bit of hairspray so it has some texture, some hold," said Louise O'Connor, head of New York's OC 61 salon. "Then, twist small chunks around a curling iron, break up the curls with your fingers, and spray it again. Don't fuss with the hair after that -- fussing is what makes it frizzy."
Of course, sometimes the frizz factor is beyond your control – drizzle and downpours, humidity and heat can turn the sleekest style into a puff ball. When weather threatens, O'Connor wards against frizz with FULL by Living Proof's thickening cream. It's the product that Emily Blunt and Leona Lewis put in their hair before hitting January's Golden Globes -- when the rain came pouring over the red carpet, their hair held up, and they partied down.
