I am traveling to Disney in the morning and want to take along 2 cans of temporary color hair spray to go with costumes - 3oz can each. Can I take in carry on luggage ? (Spray on, wash off hair color)

There are some spray cans packaged under pression, this kind isnt allowed in cabin. The label have a triangle with an explosion painted inside (international symbol) this identified the explosive product

I am not sure about this. Last time my daughter brought small hair spray can and was not allowed. You should check with TSA website or air plane agent for sure before bring any chemical to the airport.

Anything under 4oz is allowed. I strongly suggest that you put them in a zip lock bag.
