Motions Foaming Wrap Lotion, $4.99
"You usually find it in the 'ethnic' aisle but it's an amazing product for any woman with frizzy—but still fine—hair," says Allison Woodruff, a stylist at Marie Robinson Salon in New York, who uses Motions Foaming Wrap Lotion daily on clients. "It smoothes waves and curls but never leaves them droopy." Woodruff's prescription: Comb a healthy dollop from roots to ends when hair is wet. Whether you air-dry or blow-dry, you'll get silky results.
