Yes, you can take hairspray in your hold (checked) luggage, but it is subject to specific volume and safety regulations because it is an aerosol. According to most international aviation standards (like the FAA and IATA), aerosols must be "non-flammable and non-toxic" for personal use to be allowed in checked bags. The total capacity of all such articles (including hairspray, perfumes, and colognes) must not exceed 2 kg or 2 liters per person, and the capacity of each single container must not exceed 0.5 kg or 500 ml. It is essential that the container has a cap or other suitable means to prevent accidental release of the contents during the flight. While you can bring "jumbo" cans of hairspray in your checked bag that would be confiscated in your carry-on, you should ensure they are well-packed to avoid being crushed. If you are carrying "industrial strength" hairspray that is labeled as highly flammable or meant for professional use, it may be prohibited entirely, so always check the labels for "personal care" designations.
