1. “The Joico texturizing sprays are something I always have in my kit. The Beach Shake ($22.60) for medium to thick hair adds sheen and oils that the hair needs, and the Body Shake ($22.60) for fine hair doesn’t weigh it down so you’re able to brush the hair from root to tip. The more I use them, the more I’m in awe.” 2. “Coconut, almond, sesame, olive—those are all great natural oils to use to eliminate frizz. They also make the hair smooth and silky, and that goes for any hair type.” ELLE loves Kopari Coconut Melt ($50). 3. “On-set, I need products that are very versatile. With AG Firewall Argan Shine & Flat Iron Spray ($26), I can do a light mist for someone with really fine hair and just spray more for thick, coarse hair.” For details, see Shopping Guide.
