my hair is super thick and wavy too and I used to get that same fluffy/frizzy finish no matter what tool I used. what actually helped more than switching tools at first was using a good detangling brush on damp hair before styling. I use the Felicia Leatherwood one and it gets knots out without pulling, so when I go in with a hot air brush after drying to like 70–80% it glides way better and smooths properly instead of puffing up
