Katy Perry looks amazing with her pixie haircut- but what if yours looks completely unamazing? Time to grow it out! Don't avoid scissors. According to Allure Magazine, you should get a neck trim every four weeks to keep things pretty. Keep your hair healthy. Don't damage short hair by overprocessing it with color, heat, and product. Make the most of what you've got. Use mousse, spray, clips- whatever you can to glam up that in-between stage!
