Katy Perry
Weird that your roots can still get greasy when the ends crisp up in that dry recycled air, eh? To guard against the aforementioned phenomenon, Perry brings a travel-size can of texturizing spray for a just-washed feeling. Best make sure it goes in your one Ziploc baggie, or else they'll rifle through your luggage, making everybody else in your party want to hurt you.
