Which NG conditioner are you using? From the ones I've tried I think they're a little thick for cowashing. Most use a "thinner" or "lighter" conditioner like Tresemme Naturals, Suave Naturals, some of the v05 ones. I would keep the NG one as a rinse-out (RO) only. The SheaMoisture may also be building up and weighing down in conjunction with the NG cowashing.
fine - normal porosity*?- medium density - normal elasticity. Hard water. SoCal.
*Used to be low-porosity, but I lightened my hair 1-2 shades, so I may be normal-porosity now.
