Myrna, I wonder if what you described could be overconditioning. My hair is relatively low porosity and I get overconditioned at the drop of a dime. I could never use the GVP as a leave-in. However, my hair is not coarse.
2b/c wavy modified CG since July 2012
medium texture, normal porosity, normal elasticity
hair likes protein, doesn't like oils, easily OC'd

low poo: JCHCC, CJGCS
RO/co-wash/LI: YTCarrots, DB Pumpkin Seed
stylers: a bunch of stylers that are all pretty much the same (KCCC, UFDCM, CRCM, CKCJ) or ArcAngel if I need more hold
