My hair is smooth and silky after using silk infusion.  It has been reformulated so if you have used it previously note that it is a bit different in look and feel.  It is clear and a little goes a long way.  My stylist has instructed me to apply the product away from my scalp and to warm it in my hands by rubbing them together before working it into my hair.  This process worked perfectly for me.  I live in a humid climate so frizz is a year round problem but with Chi and a touch of a flat iron my hair looked salon complete.  It was not oily, just smooth and finished.  Since I wash my hair daily after gym workouts and it is colored I worry about the quality and dryness of my hair.  This is a good product and it is definitely better than some of the lower end spray-on oils which I have found unsatisfactory.  I found Biosilk too greasy and L'oreal spray on oil did nothing.
