My hair...?

MY hair is pretty much gross. nothing works. i have used pantene, dove, infusium 23,sunsilk. i dont really do anyhting wiht my hair like straighten or blow dry it or curl it...i do scrunch it wiht gelll and straighten once in a while cuz it is wavy. i hate it. i norma put it in a pony. but when i i do put it in a pony, it is all overthe place, it is notty, and more. is theree a product to control it or make it more normal?
