Which shampoo will volumize my hair?

First off i'm not sure if "volumize" is a real word haha anyways which shampoo will give my hair the right amount of volume?? Ive tried Aussie voluminous shampoo but it didn't really work that well. Any type of brand is fine i just need that volume in my hair!! lol Plus any sprays or gels to give my hair volume before/during/after blow drying my hair will be fine. Thanks!!
