You unfortunately can't add much more shine to laminate than what it's finish was intended to provide - or at least not permanently. For example, If you purchased laminate floors with a matte finish, there's no changing them to a high gloss finish.
If you're looking for a pick-me-up before hosting guests or taking photos, though, there are products that provide temporary laminate floor luster - similar to how Armor All adds temporary shine to your car's tires. Just make sure you choose a product designed specifically for laminate, and not for vinyl or some other type of flooring. Useing the wrong product could result in cloudy finishes or other unexpected results.
