What products can you use on your hair to make it glossy and shiny but also smooth and frizz-free?

For thick-ish, wavy, dry-ish hair- what are some products I can use to make it glossy but silky? I don't want any products that will make your hair oily or waxy but one that can deliver the shine and the softness... what are some brand names and where can I buy them, preferably at any ole store rather than a salon. If the best ones ARE from salons, can I get some names? I have this major interview coming up and my hair needs to be at its best!
