If I get delinquent about caring for my hair, it gets pretty darned frizzy. I use an extremely good frizz control curl enhancer that helps keep it more tame. Luckily they also sell it in CZ, but I have used it for years now. You can see it at Curl Defining Cream for Curly Hair | Hair Styling | Moroccanoil | Moroccanoil It's not cheap, but it lasts a long time since a little goes a long way, even on my huge amount of head hair. After washing/conditioning, I put in a little of this product and then scrunch my hair. If I didn't "scrunch" my hair, it would not have as nice and defined curls. That method would likely better define waves, as well.
