Good Daily Moisturizers For Relaxed Hair?

I was hoping I wouldn't have to do this. I have relaxed hair that's pretty thick in density, it can be very difficult keeping moisture and luster in it. I basically wash/cowash it, deep condition and let it air dry. I avoid any kind of heat styling because getting it relaxed and flat ironed then is enough, and I want to keep it as less dry as possible. Would anyone know of any really good daily moisturizers, that would help keep it conditioned and healthy? please only serious answers, and please don't suggest "oils" I"m looking for cream based moisturizers. I tried to look up something online, but it's been over taken by natural nuts, so here I am. Thank You,
