The TSA allows aerosol cans in both carry-on and checked luggage, but they must comply with the 3-1-1 liquids rule. This means that the can must be 3.4 ounces or less, and fit in a clear, quart-sized zip-top bag. It's similar to packing a small toolbox - you need to make sure everything fits neatly and follows the rules.
But why are there rules around aerosols in the first place? It's because they can be pressurized containers that might release their contents during flight, which could be a problem. Imagine a can of soda shaking up on a plane - not a big deal, but still a bit of a mess. Now, imagine that can is a hairspray can or deodorant can - it's a bit more concerning.
Another thing to consider is the type of aerosol you're trying to bring on the plane. Personal care items like hairspray, deodorant, and shaving cream are usually okay, but industrial-strength aerosols or flammable liquids are a no-go. It's like trying to bring a power tool on a plane - just not a good idea.
