I know when I first started with CG method, I felt like I needed way more co-wash than I actually did. Remember that there are ingredients in the conditioner that work as surfactants, and the real cleansing comes from the motion of massaging your scalp. I'd try cutting back to the amount you use when you use a cleanser and see if your scalp feels clean enough. HTH!
My hair: 3b, corkicelli, medium porosity, medium texture, medium/thick density
Co-wash: DevaCurl NoPoo
Rinse-out: GVP Conditioning Balm
Leave-in: KCKT, Suave Naturals Coconut, or my rinse-out!
Gel: SS FHG (my new HG!!)... I also like HESMU, AIF, CJ CQ, BRHG, CJ PP and the occasional LALSG
CG and loving it!
