Suave followed by Tresemme might not be rich enough for your high porosity hair, I am high porosity and need plenty of leave in conditioner, it could be more important than gel for frizz control and clumping.

I never used to understand frizz when wet but occasionally I get it when I've used my protein rich/ oil free conditioner several washes in a row. I don't think the protein itself is the cause as such since it's giving me good hair much of the time, my hair seems to need a little oil in my routine.

Another possibility is that fifteen minutes is too long a plop, porous hair can dry out fast especially if you are not using a rich leave in conditioner but only water based products. I'm having best results with flour sack towels, takes out less water so doesn't overdry the hair. I also lightly scrunch out water with the towel more often than I plop so I can hit the wetter areas and leave the ones that tend to frizz.
