Alicia Keys’ natural curls are the perfect combination of cute, sexy, and easy! Simply apply a leave-in conditioner like Carol’s Daughter Hair Milk ($12, sephora.com), scrunch, diffuse, and pull the top half back in an elastic ponytail holder.
There’s nothing sexier than a slightly “undone” updo—and it only takes minutes to achieve. Recreate Rachel Roy’s high topknot by sweeping long hair (or a fall) into a super-high pony, twisting it into a bun, and then gently picking out random strands with the sharp end of a fine-tooth comb.
Halle Berry’s signature pixie cut manages to be both incredibly sexy and edgy at the same time! The best part? It takes two seconds to style. Wrap your hair in a silk scarf at night to keep the sides flat, and in the AM, run a lightweight wax like Rene Furturer Styling Wax ($23) between hands and then finger-tousle the top portion.
