The classic Newyorican look—Jennifer Lopez's half up style—is simple. Apply a light mousse like Garnier Fructis Hydra Recharge Moisture Whip Leave-In Conditioner. Part your hair in half, leaving about an inch strand from the top section out. Pull the top section into a high ponytail, then wrap the remaining strand around it. Lightly spray your hair with your favorite hairspray.
