Can I Take Aerosol Hairspray on an Airplane?
Aerosol hairspray is considered a flammable item and is only allowed in carry-on luggage when it is for personal use and in the restricted 3 oz. quantity. The hairspray must also be in a clear, plastic zip-top bag. Please refer to http://www.tsa.gov/travelers/airtravel/prohibited/permitted-prohibited-items.shtm for an updated list of prohibited items.
