+1 to knowing hair properties. For second day hair, I have had luck with either the washcloth method (there is a post on it here somewhere) or simply applying CJCIAB to dry hair and scrunching it in (its a light, thin, watery gel). I've actually achieved third day hair with the gel.
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.
