Frequently Asked Questions
Can aerosol cans explode on a plane?
Modern aircraft cabins are pressurized, so personal care aerosols are safe. TSA-approved toiletry aerosols are specifically designed to handle pressure changes.
What happens if my hairspray is over 3.4oz in carry-on?
TSA will ask you to surrender it, check it in your luggage (if possible), or dispose of it. They cannot make exceptions for the size rule.
Can I use hairspray at the airport before my flight?
Yes, you can use hairspray in airport bathrooms. Just make sure to store the container properly in your quart bag before going through security.
