Are there any ideas on how scene hair looks from behind, and how I should buy everything?

I need to know how scene hair looks from behind because I have had problems lately. I also need to buy alot of stuff for scene, but without causing too much trouble or going overboard with the expenses. So should I buy stuff gradually, or get what I really want first? I really need advice on this one! Also, are there any good ideas for styling the hair – other than teasing it? Thanks.
