Hair products are available in a variety of formats, including creams, gels, lotions, and sprays. All the other kinds are quite simple to bring on a flight, but carrying a spray, like a hair spray, presents a challenge. But the real question is: can you bring hairspray on a plane ? The answer is yes ; Hairspray can be brought on board in both carry-on and checked bags, but only in a certain amount. Your hairspray needs to be kept in a container that is no larger than 3.4 ounces and that fits inside the one specified one-quart clear resealable bag.
