If some of your curls are still looking a little fuzzy after they dry, I suggest trying two things:

The first is that if those curls seem to be pulling apart, they might actually be two curls that got defined together as one. If that's the case, they will keep popping apart (because it's really two curls that want to do their own things independent of each other). If this is the case, you might want to try making smaller curls in the fuzzy areas. Like divide the bigger curls in half, and then smooth them. There are some areas of our hair that have smaller curls than other sections, and these smaller curls often need to be defined into smaller curls to keep them from fuzzing.

The second thing I'd suggest is, after your hair dries, and it seems like it's one curl that's just drying kind of fuzzy, is to wet your hands, add a bit more of one of the conditioners I recommend to your hands, rub your hands together, and smooth that over the fuzzy curls. Go over each fuzzy curl one at a time. They should feel wet with conditioner when you are done. Then let them dry again. The extra conditioner should hold the fuzzy hairs together a bit better. If it's still fuzzing, you could just run a little conditioner over the curl for a firmer hold. Then let it dry.

And some curls just fuzz a bit more than others. My tightest curls always have some hairs that are just curling in a totally different way than all the rest of my hair in that area, and sometimes I have to let them be. It's in the nature of curly hair for there to be some fuzz no matter what. But usually trying those two techniques in the fuzziest spots cuts down on most all the fuzz.
