You're standing over an open suitcase. It’s midnight. Your flight leaves in six hours, and you’re staring at that ceramic 1-inch wand like it’s a contraband explosive. It feels like it could be a weapon, right? I mean, it’s a blunt metal rod that gets hot enough to sear a steak. So, can you take a curling iron in your carry on without getting pulled into secondary screening?
Yes.
The short answer is a resounding yes, but—and there is always a "but" when the TSA is involved—the rules get weirdly specific once you move away from standard plug-in models. If you’re rocking a basic corded iron, you’re golden. Toss it in. But if you’ve spent $200 on a fancy cordless butane-powered styler, you might be about to donate it to a government trash bin.
The TSA Reality Check for Hair Tools
Let’s be real: airport security isn't actually worried about your curls. They care about things that catch fire or go "boom."
According to the official Transportation Security Administration (TSA) guidelines, electric hair straighteners and curling irons are perfectly fine in both carry-on and checked bags. They don’t even require you to take them out of your bag like a laptop. You just leave it nestled between your jeans and that novel you probably won't read.
However, there is a massive caveat for the "glam-on-the-go" crowd. Butane-powered curling irons are the exception. You are allowed exactly one of these in your carry-on, provided it has a secure safety cover over the heating element. You cannot, under any circumstances, pack spare butane cartridges. Not in carry-on. Not in checked. If the TSA agent sees a loose refill canister on the X-ray, they’re going to have a very long conversation with you.
Why Your Cordless Iron Might Get Confiscated
Technology has made hair care easier, but it’s made flying harder.

Most modern cordless tools use lithium-ion batteries. You’ve probably heard the horror stories about Samsung phones or hoverboards catching fire in cargo holds. Because of this, the Federal Aviation Administration (FAA) has a bit of a panic attack if lithium batteries are checked into the belly of the plane.
If your curling iron is battery-operated, it must stay with you in the cabin. If the gate agent forces you to check your bag at the last minute because the overhead bins are full, you have to rip that iron out of your suitcase and carry it onto the plane by hand. Leaving a high-capacity lithium battery in the cargo hold is a major safety violation. Honestly, it’s just not worth the risk of being the person who started a fire at 30,000 feet.
The Corded vs. Cordless Debate
Most pros, like celebrity hairstylist Jen Atkin, often suggest sticking to corded tools for international travel anyway. Why? Because batteries die, and charging them in a foreign airport is a nightmare. Plus, corded irons have zero "restricted item" baggage. They are just hunks of plastic and metal.
International Travel and the Voltage Trap
Wait. Stop.
Before you shove that iron into your bag for a trip to Paris or Tokyo, look at the handle. If you see "110V" and nothing else, leave it at home.
The US runs on 110-120V. Most of Europe and Asia runs on 220-240V. If you plug a single-voltage American curling iron into a wall in London using just a plug adapter, you will likely smell smoke. And it won't be from your hair. It’ll be the internal circuitry of your iron frying.

You need Dual Voltage tools. Look for a label that says 100V-240V.
If you have a Dyson Airwrap or a high-end T3 iron, check the fine print. Many of these expensive tools are not dual voltage. People have literally melted their $500 Dysons in Europe because they thought a cheap $5 plastic adapter would regulate the electricity. It won't. You’d need a heavy, expensive power converter, which usually ends up breaking the tool anyway.
Packing Hacks to Keep Your Iron (and Clothes) Safe
So you've confirmed you can take a curling iron in your carry on. Now, how do you pack it so you don't ruin your favorite silk dress?
- The Heat Sleeve is Non-Negotiable. Even if you think the iron is cool, it’s probably not. A silicone heat-resistant pouch is a lifesaver. It protects your clothes from singe marks and keeps the cord from tangling.
- The "Center Mass" Rule. Pack the iron in the middle of your suitcase. Use your soft clothes as padding. If your bag gets tossed around by a disgruntled baggage handler, the ceramic plates won't crack.
- Wait 15 Minutes. Seriously. Don't use the iron and immediately throw it in the bag. Give it a full 15 to 20 minutes to reach room temperature.
I once saw a woman at O'Hare who had clearly packed a hot iron. Her bag started smoking in the security line. It wasn't a fire, just the nylon lining of her suitcase melting onto the barrel. It smelled terrible. The TSA agent was not amused. Don't be that person.
Gas-Powered Irons: The Odd One Out
Let's circle back to those butane irons because they are the "black sheep" of the hair tool world. Brands like Braun or Conair used to make tons of these. They’re less common now, but if you own one, listen up.
The International Civil Aviation Organization (ICAO) is very strict about these. You get one. It must have a cap. If that cap is missing, it’s trash. If you try to bring a pack of refill cartridges, security will take them.

Why? Because pressurized gas in a pressurized cabin is a recipe for a bad day. If a cartridge leaks, it’s a fire hazard. If you absolutely need a butane iron, buy the refills at your destination.
What About the "Dangerous Object" Rule?
TSA agents have a lot of "discretion." This is a fancy way of saying they can take away anything they think looks suspicious.
While a curling iron is on the "Green List," if yours is particularly heavy, has sharp decorative spikes (yes, those exist), or looks like it could be used as a club, you might get flagged. It’s rare, but it happens. If you’re worried, keep it in its original case or a dedicated travel bag so its purpose is obvious.
Actionable Steps for Your Next Flight
Before you zip that suitcase shut, run through this checklist. It’ll save you a headache at the terminal.
- Check the Voltage: Look for "100-240V" on the handle. If it's not there and you're leaving the country, buy a cheap travel iron at your destination.
- Identify the Power Source: If it's lithium-ion, it stays in the carry-on. If it's butane, it needs a cap and no extra refills.
- Insulate the Barrel: Use a silicone sleeve. If you don't have one, wrap it in a thick cotton towel—but only once it's 100% cool.
- Zip Tie the Cord: Don't just shove the cord in. Use a Velcro strap or a rubber band. Tangled cords lead to frayed wires, and frayed wires lead to short circuits.
- Screenshot the TSA Site: If you’re really nervous, keep a tab open on your phone to the TSA "What Can I Bring?" page for hair irons. It’s rare that an agent doesn't know the rule, but it’s nice to have "proof" just in case.
Traveling with your styling tools doesn't have to be a gamble. As long as you aren't trying to smuggle a gallon of butane or a 110V iron into a 220V country, you’re going to be fine. Just give your iron time to cool down, pack it securely, and keep your cordless devices in your hand luggage. Your hair—and the TSA—will thank you.
