My hair also looks better and more defined when I diffuse. It also takes a million years to air dry when I have products in it, and the products make my hair heavier when it's wet (which means loosened, stretched out curls), so I usually diffuse if I want it to look nice.
2c, fine, extremely dense, color-treated, high porosity. Medium length (longest layer just grazes my shoulders).
