Daily leave in conditioner. I think it used to make my hair silkier, but I might be using it differently than I used to.

This is a really good leave in treatment/conditioner. It untangles hair, and if you frequently blow dry your hair, it helps prevent damage it. You can actually feel the smoothness after a blow dry instead of dryness. The only catch is, it can sometimes dry hard (like gel) in your hair if you don't blow dry it - so if you don't plan on blow drying, make sure you brush it through your hair evenly!
