The best way to avoid frizz with wavy hair is to let it dry naturally. Apply a dollop of wave-enhancing mousse (try: Aussie Catch the Wave Mousse and Leave-In Conditioner, $4.99) to damp hair and comb it through. If you use a diffuser, try not to touch your hair too much, or else you’ll create more frizz for yourself.

The good thing about wavy hair is it’s “easy to blow out and iron” using the same techniques as straight hair, Prieto says. Just keep in mind that it will require more protection against frizz than straight hair, so apply a bit more anti-frizz serum after you’re done.
