How to get the look:
1. Blow-dry hair smooth, but be sure not to lift at roots. "The look is very flat with a big flick," says Arrojo
2. Apply a spritz of hairspray and, with a curling iron or hot brush, roll the front of hair back. "That will give you extra hold."

Bonus tip: "The lower the parting, the more sexy and dramatic it will look."
