Heidi Klum, rule breaker
Step 1: You need a really good blowout—so allow plenty of time to do it right.
Step 2: Start by applying volumizing mousse like Victoria’s Secret So Sexy Volumizing Mousse, $8.99 to damp hair.
Step 3: Blow dry your hair straight, but not pin straight (the goal is smooth, with some bend, like Heidi’s). Working in 2-inch sections all over will help. (Clip up the top sections in order to reach the underneath sections of your hair.)
Step 4: Mist with shine-boosting hairspray like Pantene Pro-V Ice Shine Hairspray, $4.99.
