If you're always at a loss to explain what you want to stylists, Aveda has just debuted a new app that's a great resource for styling and color. The app, My Aveda Style (free), has everything from Fashion Week backstage styling videos to a hair lookbook that allows you to show your stylist what you like. Instructions for getting the looks are included, as well, so if you go to an Aveda salon regularly, it definitely facilitates good communication with your stylist. And even if your salon isn't Aveda, it's pretty informative and helpful. Plus, the backstage Fashion Week videos are the perfect way to get a taste of designer hairstyling's glamour (and craziness).
