What is a really good shampoo?

I am looking for a nice, cheap shampoo that really softens my hair and doesn't smell bad (haha). Something that makes it shine, smell good, and VERY soft and restores it. For about a year I straightened my hair so badly that it is so ugly. I need something that helps it so It can grow too it hasnt grown at all since I used to Straighten it. :/ help!
