I don't wear much make up either, but hair is normally my focus.

My "tip" is to not wash your hair every day. Your hair's natural oils are amazing at protecting your hair from heat (curling iron, straigthener) or pollution. Unless your hair is ueber oiley, it's best to wait a day. By all means wash your body though!

If you're worried about the smell or shine, put a little baby powder on your roots, flip your hair over, and blow dry it a little bit. I try to use as little product as I can, but that's just me. There are also hair perfumes you can buy if your hair is really stenchy.
