As curl experts we get this question a lot. The answer is moisture. After washing (with a sulfate free shampoo), condition with either an @innersenseorganicbeauty or @mydevacurl conditioner. Rinse lightly, leaving in lots of conditioner before applying your styling products to your soaking wet curls. Blot the moisture out with a microfiber towel, they're a smoother texture than terry cloth, to keep that frizz from creeping up on you. No touching as your curls dry! Once dry you can shake it out and scrunch but don't pull down or tug on your curls, that could contribute to frizz.
For 2nd/3rd day hair spritz with a spray bottle of water with some conditioner in it. Shake, spray, & diffuse for a couple minutes to revive.
Ask your favorite curl expert which products would be ideal for your specific hair type.
