Can You Bring a Hair Straightener on a Plane?
QUICK ANSWER
Yes, you can bring a hair straightener on a plane. Standard corded flat irons are allowed in both carry-on and checked bags. Cordless butane or gas-powered stylers are limited to one in your carry-on with a safety cover, and their gas cartridges are banned.
A hair straightener is an easy item to fly with as long as it is a normal corded flat iron. The only complications come from cordless models that run on gas or lithium batteries, which have their own rules. Here is how to pack your straightener, curling iron, or other hot tool for a flight.
Can you bring a hair straightener on a plane?
Yes, a standard corded hair straightener is allowed in both carry-on and checked baggage. According to the TSA, flat irons and other plug-in styling tools pass through security without a problem, and there is no size limit. Carry-on is a good choice so you can protect the tool and it stays with you. The only versions that come with extra rules are cordless straighteners, which run either on a butane gas cartridge or a lithium battery, and those are covered below. For the plug-in flat iron most people own, packing it is simple: put it in either bag, ideally after it has fully cooled, and you are set.
Should you pack a straightener in carry-on or checked?
Either works for a corded straightener, though carry-on has small advantages. Keeping it in the cabin protects the tool and lets you touch up on arrival, and there is no downside since a plug-in flat iron has no restricted components. The one practical tip is heat: make sure the straightener is completely cool before you pack it, since a hot tool can scorch clothing or a bag. If you are tight on carry-on space, a corded straightener is perfectly safe to check; just cushion it so the plates do not get damaged. Wrap the cord loosely to avoid strain. Whichever bag you choose, a fully cooled, corded straightener travels without any issue.
What about cordless straighteners?
Cordless models are where the rules tighten, and it depends on the power source. Butane or gas-powered cordless straighteners are limited to one per passenger in your carry-on only, and the device must have a safety cover over the heating element to prevent accidental activation; the spare gas cartridges or refills are prohibited in both carry-on and checked bags. Battery-powered cordless straighteners that use a lithium battery follow the lithium rules: keep them in your carry-on, since devices with lithium batteries are safest in the cabin and spare lithium batteries are required to be there. So a cordless straightener can fly, but always in your carry-on, and never with extra gas fuel.
Do curling irons and other hot tools follow the same rules?
Yes, the same logic applies across styling tools. Corded curling irons, hair dryers, hot brushes, and crimpers are all allowed in both carry-on and checked bags with no special handling beyond letting them cool. Cordless versions follow the same split as straighteners: a butane or gas-powered curling iron is limited to one in your carry-on with a safety cover and no spare fuel, while battery-powered tools follow the lithium-battery rules and stay in the cabin. So whether it is a flat iron, curling iron, or dryer, a plug-in model goes in either bag, and any cordless gas or battery model rides in your carry-on. Pack all of them cooled and cushioned to protect the tool.
