I scrunch with CLU cloths then diffuse to about 80%. To diffuse: I have a big bowl diffuser with long fingers. I do my hair in 3-4 sections. I cup each section into the diffuser and hold it against my scalp allowing room for a little air flow at the roots. I dry each section for two minutes.

Then I clip the roots (with regular clips I have but I want those roller ones!!) and place my hair into a CLU cloth for a while. I've noticed the longer i leave the cloth on the better my hair is. Then I just let it air dry the rest of the way.

I *think* the reason it looks better is that it dries faster and I am able to keep my hands off it - if I allow it to air dry it takes forever and it gets touched a lot. I also think with air drying, the weight of the water pulls the curls as they dry. Diffusing gets much of it out before I let it down to air dry.
remember, with all advice or suggestions for your hair, YMMV!!
My hair:
2b wavy, medium texture, low porosity, med-high density. Protein finicky.
My routine:
Cleansing: DCNP, every 4-5 days (occasionally use CJ cleansers).
RO: CJSC, occasionally use JCDC
Gel: KCCC, CJCIAB for 2nd day hair (sometimes third)

Heat is my friend: warm water rinses, steam caps, and diffuse dry. I love CLU cloths and my Denman.
