Okay, post-shower update. I did a sulfate wash with YTC and followed up with GVPCB. Went back to KCCC topped with the Garnier gel and pixie diffused. Waves seemed happier and the frizz looks a bit more like what I'm used to seeing when I over-condition (more "fluffy" than anything else).
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!
