I'm guessing you're wanting to blend the props into the skin or do you want to be sandy all-over ?
I'd probably consider doing body-paint with some actual sand mixed in (since sand shouldn't be toxic or dirty and more than anything you would use to simulate it). Or you could add the sand after painting and use an adhesive if you have to.
I can't really tell what that haircut is supposed
to be. Is it really striped or is it just kind of curly ?

You could do that or you could make a cap that you just put over your real hair - like sculpted and molded latex or something. It would give you a really cartoony and unreal look while the curls would provide a more realistic take.
