To style your natural curly hair without frizz, begin by using a sulfate-free shampoo and a conditioner designed for curly hair. After washing, gently scrunch your hair with a microfiber towel or cotton T-shirt to remove excess moisture, avoiding rubbing or twisting motions. Apply a leave-in conditioner and a frizz-fighting serum or cream, distributing the product evenly through your hair. Finger-comb your curls to detangle and define them, and then either let your hair air-dry or use a diffuser attachment on your hairdryer at a low heat setting. Avoid touching your hair while it dries to minimize frizz.
