Can I bring shampoo and conditioner on a plane?

Shampoo and conditioner — as well as and roll-on, aerosol, and gel deodorant — must be travel-sized and fit into one quart-sized, zip-top bag to meet standard carry-on bag requirements. If any of the containers are larger than 3.4 ounces, you will need to pack them in your checked luggage.



Yes, you can bring shampoo and conditioner on a plane, but the rules differ significantly between carry-on and checked luggage. For carry-on bags, you must adhere to the 3-1-1 liquids rule: each container must be 3.4 ounces (100ml) or less, and all containers must fit into a single, quart-sized, clear plastic zip-top bag. If you have larger bottles, they must be packed in your checked luggage, where there are no specific volume restrictions for standard toiletries. In 2026, many international airports (like those in London or Madrid) have installed advanced CT scanners that allow you to leave liquids in your bag and potentially carry larger volumes, but this is not yet a global standard; the 100ml rule remains the safest bet for domestic and international travel. It is a peer-to-peer tip to use "solid" shampoo and conditioner bars if you want to bypass the liquids bag entirely, as these are classified as solids and do not count toward your liquid allowance, saving precious space for other essentials.
