@Firefox; So, you're saying it's most likely the protein that's causing the frizz? Could doing a coconut oil treatment possibly help with some of the frizz? And if protein is the culprit, should I cut back on it or cut it out completely?

For my low-poo, I used the Organix Coconut Milk shampoo, which I think has a 'cone... uh oh. My sulfate shampoo was was YTC Nourishing, which I used after the Organix. I applied KCKT, followed by SheaM C&S milk, followed with Pantene Curls mousse. I'm thinking that this time it may have been product overload because I used a detangler and a L/I, plus a ton of mousse, but this is a consistent problem. Everything that I'm cycling through product-wise is:

Cowash: SN Coco, V05 MM
Low-poo: Organix Coconut Milk or SheaM C&S shampoo
Sulfate wash: YTC Nourishing
R/O: GVPCB, Ion Effective Care
PT: GVP K-Pac, Colorful NPF
L/I: KCKT, SheaM C&S milk (still not sure I actually need a leave-in)
Stylers: LA Sport gel (yellow), Pantene Curls mousse
2B with 2A underlayer, very frizz-prone, low porosity, high density, fine/med thickness, high elasticity
I cut my hair -- from almost waist length up to armpit length!

Officially no longer CG --- my hair plays much nicer with sulfates as 'cones!
