Taking forever to dry indicates low porosity. Chemically treating hair can alter the porosity...but doesn't automatically mean high porosity. Does your hair seem to take a while to get wet? Do some products (oil, for example) tend to just sit on your hair? Run your fingers up a strand - is it smooth? Do a float test - place hair in a cup of room temperature water, does it float? That all also indicates low porosity.

Good luck.
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
LI: KCKT or CJSL
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.
