The Transportation Security Administration (TSA) is mostly worried about things that go boom, not things that go “sizzle” on your split ends. Straighteners, curling irons, and flat irons are all considered personal care items. Unless yours is somehow weaponized with a hidden knife inside the ceramic plates—which, please don’t—you’re golden.
Just remember: the TSA agent might ask you to remove it from your bag if it looks suspiciously large or cordy. But generally, they’ve seen a million straighteners, and yours is not special enough to trigger a pat-down. Sorry to break it to your ego.
But Wait—What About Gas or Batteries?
Ah, the fine print! If you have a cordless, gas-powered straightener (yes, those exist for outdoor adventures, apparently), the rules change a bit. The lithium-ion batteries inside cordless models are absolutely fine in carry-on bags, but the FAA frowns upon them in checked luggage. So toss that fancy battery-operated star in your backpack, not your suitcase.
If your straightener is a vintage relic that uses butane cartridges—like a tiny flamethrower for your hair—you must leave it at home. Butane is a no-fly zone in both checked and carry-on bags. Unless you’re a professional fire breather, skip it.
