Thin, stringy, greasy wavy hair help?

you need to make sure you are washing out the shampoo/conditioner VERY well. a lot of girls dont wash it out well enough, and it causes the exact same problem you are having. take your time washing your hair and make sure it is thoroughly washed! you could also try getting a product to put in your hair that you can spray in to help come up with a hairstyle like to help it curl and stuff? another very helpful thing to do is get a perm. a lot of girls at my school are getting curly perms that look great and in style! its a quick fix in the morning and you're ready to go! hopefully that helped with both situations (:
