I want to know what I need to do to make my ivy leaves look glossy or shiny.

There are leaf shines out there in nurseries and probably in box stores like Lowe's, Home Depot and Walmart. I have always heard bad things about leaf shine products, causing leaves to blacken over night and clogging leaf pores, although have never used them myself. It might be healthier just to keep the leaves clean by an occasional shower which will also keep any pest infestation down.
