I really think its the lacio lacio & chi silk infusion. My hair never comes out as shiny when I don't use lacio lacio. Salerm 21 also works as a great substitute.
Well, my hair tends to be very porous and and oils don't do jack for my hair (they either sit on top of my hair or they are absorbed in 5 minutes and leave my hair feeling dry). However, I do use shea butter in the winter. For me, Vaseline is much heavier and is capable of smoothing my cuticles and keeping them closed.
