So you know my background: I went 'no-poo' a year and a half ago. Now, I use DC no-poo maybe once a week (and I'm talking a very tiny amount - just to get a couple of spots that feel oily.) In between I am WO. It works great for me too. (I condition my length regularly.)

When I begin to notice build-up on my scalp, I will do a BS/ACV wash. It helps a lot and doesn't set you back with WO. You might consider that instead of a shampoo/conditioner thing, plus it's cheaper.
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.
