I always plop using a Curlease towel. I leave the towel on whole I put my makeup on. After plopping I use either CIAB or Curls Gel-les'c as a serum. I scrunch in a small amount and then diffuse.

I only diffuse until my curls are stiff and formed. I go by feel. The time diffusing can change depending on what products I use. Some products make my hair dry really quickly, while other products hold onto the moisture. As long as I don't over-dry my hair, I don't get any frizz.

The other thing that is very important in preventing frizz is using the right products and enough of them. If I don't apply enough product or I miss portions of my head, I will get frizz.
