The Transportation #security Administration (TSA) has specific rules and regulations regarding bringing aerosol hairspray on a plane.
In general, you are allowed to bring a small aerosol hairspray on a plane as long as it meets the TSA's size restrictions. Aerosol hairspray containers must be 3.4 ounces (100 milliliters) or less to be allowed in your carry-on baggage.
If your aerosol hairspray container is larger than 3.4 ounces, it must be placed in your checked baggage.
