I'm pretty sure if you're shampooing, it would get out any protein build-up - someone correct me if this is wrong
There is an ingredient called Stearalkonium Chloride that is in the majority of conditioners. This ingredient gives me frizz galore & makes my hair feel "coated"
One of my most favorite conditioners for pure moisture is the Nature's Gate Herbal. A lot of the other flavors of NG have the above SC ingredient in them & I haven't even bothered trying them, but the Herbal gives me tons of moisture w/o weighing my hair down, & boosts my waves/curls.
