This particular product you can use as both. I check the ingredients and it "cone" based. In this case "glossing" just makes the product sound good, but it has been the best by far.
Chi Silk Infusion, worked great the first few times I used it, but I does not allow me to moisturize, by day 3 my hair was dry and crispy
Proclaim glossing polish serum, way to heavy but it was good for sealing my ends.
