As the temperature drops, show your curly locks some love with the Ouidad Moisture Lock Leave-in Conditioner. This season’s beauty must-have packs a punch against dry hair with its body-busting nutrients including green tea and pro-vitamin B5. We suggest working a palm-size dab of the conditioner through partially damp hair. To maintain your beautiful bounce, air-dry your marvelous mane to allow the conditioner to saturate the hair from root to tip. The end result is luscious curls that look and feel smooth ($22, www.ouidad.com).
