I get that type of frizz, too. I think it's surface frizz.
I don't diffuse, but I've been noticing that I get it more when I use KCCC alone, without a stronger gel on top.
Wonder what else causes this type of frizz?
ETA: There's a post called "Types of Frizz" that explains all the different kinds of frizzies....I cannot for the life of me find it right now
