Is there a shampoo or something that will help my hair?

I'm really tired of my hair. Once I get out of the shower it's alright. But as the day goes on it gets knotty and clumped together. I just want to be able to have hair I can actually do stuff with and not have to brush it every time a breeze comes. I use Suave right now and I'm wondering if it's not enough. Is there something that can help me hair, shampoo, anything??Is there a shampoo or something that will help my hair?

Use conditioner. and mousse to keep it where you brush it .
