Music festivals have become just as much of a Summer staple as fireworks and ice cream trucks. But for the beauty obsessed, they might cause a rise in anxiety levels. No showers or mirrors, sleeping outside (if at all), and spending long days under the hot sun don’t exactly lend themselves to a successful beauty routine. Luckily, Beauty Flash came up with a handy-dandy little chart to save the day. If you’re heading to Lollapalooza in August, be sure to take and peek for some pretty important information, like how to keep perfume on longer, straighten your hair with no power cord, and glitter like the High Priestess of Music Festivals herself, Vanessa Hudgens.
