Your goal here is to make sure your strands don't melt before you even hit the dance floor. In this case, hair spray is your best friend. But you need to choose the right one. "A hair spray like Sebastian Shaper Zero Gravity Hairspray ($19) is a lightweight and brushable product that will keep your hair set for the whole event," notes Benvenuto. "Other options are Oribe Superfine Hairspray ($32) or Moroccanoil Luminous Hairspray ($23), which are also both light and touchable."
