Back to school beauty tips?

I want to look my best when school starts in a month. Do you have any haircut ideas or tips to make my hair look its healthiest. My hair is brown about and inch or two below my shoulder and is wavy/curly. I wear eye shadow, eyeliner, and mascara. Tips to make my makeup look its best? Back to school outfits would be helpful. I mainly like to shop at forever 21, abercrombie, hollister, and american eagle. Also tips to make my skin the healthiest it can be.
Thanks a lot!
