Batiste Sweat Activated Dry Shampoo ($10)

I washed my hair every single day at Coachella because the dust is actually insane, but I still used dry shampoo, and this one from Batiste was key. It's sweat-activated, which means you put it in before you even start sweating, and then it kicks in throughout the day. I sprayed it into my roots before heading out to the festival, and it basically prevented my hair from collapsing the second I got hot. Instead of looking flat and kind of greasy by midday, my hair actually held some volume. I typically use it before workouts when I want my blowout to last, but it's easily become a festival must-have.
