We've all been there. You're standing in line at security, preparing to remove your shoes and belt and put your liquids in a little baggie, when you realize you have no idea what the TSA's rules are.

Can you bring dry shampoo on a plane? Can you pack your shampoo and conditioner in your carry-on? Do you really need to throw away that half-empty bottle of lotion?

The TSA website has a searchable database of items that are and are not allowed on planes, but it can be hard to find the answers to specific questions. So we've done the legwork for you and compiled a list of some of the most common—and most surprising—items that are allowed and not allowed on planes. Here's everything you need to know about packing for your next flight.

Can I bring…

Dry shampoo:

Yes! The TSA says "non-liquid aerosols" like dry shampoo are allowed in carry-on and checked bags. So go ahead and pack your favorite can of dry shampoo in your carry-on to freshen up during your flight. Just make sure it's 3.4 ounces (100 ml) or less so it fits in that little quart-sized baggie.

Shampoo and conditioner:

Yes, as long as they're travel-sized bottles that are 3.4 oz (100 ml) or less and fit in your quart-sized baggie. If they're larger than that, they'll need to go in your checked bag.

Lotion:

Yes! You can bring lotion in both carry-on and checked bags. The size limit for lotions Less than or equal to 3.4oz (100 ml) allowed.

Makeup:

Yes! Makeup is allowed in both carry-on and checked bags. However, there are some restrictions on liquids, gels, creams, pastes, and aerosols (like nail polish). These items must be 3.4 ounces (100 ml) or less per container and must all fit in your quart-sized baggie.

Hair straightener:

Unfortunately, hair straighteners are not allowed in carry-on bags because they can be used as weapons. However, you can pack them in your checked bag.

Curling iron:

Curling irons are treated the same as hair straighteners—they're not allowed in carry-on bags but can be packed in checked bags.

Conclusion:

Now you know everything you need to know about packing your beauty products for a flight. So go ahead and throw those travel-sized bottles of shampoo and conditioner into your carry-on—and don't forget your dry shampoo!

Just make sure all of your liquids, gels, creams, pastes, and consols are 3.4 ounces (100 ml) or less per container so they'll fit into that little quart-sized baggie.

And if you're still unsure about what you can bring on a plane, remember that you can always search the TSA's website or reach out to a customer service representative for more information.
