I have fine 2C/3A hair, low porosity, very finicky about products. It lets me know what it doesn't like by instantly becoming a limp greasy mess.
One of the only mousses I've been able to use with good results is Peter Lamas Volumize Me Mousse. It gives me good volume and definition, and if I only use one styling product (like on a weekend when I know I'm riding my bike, or whatever sweaty work stuff I get into), it's this one. I put one pump in my hand, rub it between my palms, flip my head upside-down, and thread my fingers in between my curls near the scalp, squeeze, and repeat until my palms are mousse-free. Usually it takes two to three pumps to do my whole head. Then I cup/scrunch the ends with another pump.
If I'm going to use another product, like KCCC which I'm experimenting with right now, I don't do my ends and I use KCCC on them instead. I've also had good results doing KCCC in the shower before I "headbang" and then doing the mousse on top.
