I use HESMU spray gel sometimes after plopping and before I diffuse or air dry, even. It doesn't make me crunchy, but then again I'm high porous, so maybe that plays in.

I also use GF flexible hold hairspray on occasion. Usually just if I need extra humidity control that day, or if my hair feels too soft after diffusing or SOTC. When that happens I know my curls will droop by the end of the day - but again I'm high porous, so that causes drooping in higher dews. Not sealing causes me drooping, too, for the opposite reason - my porosity causes me to lose moisture. Sigh. So particular.
