Can You Bring Hair Straighteners on Planes? TSA Rules

Reader-supported. We may earn a commission on purchases through our links. Disclosure ›

Yes, you can bring hair straighteners on planes. A regular corded hair straightener or flat iron is allowed in both carry-on and checked luggage. Cordless hair straighteners are the exception: if they contain a lithium battery, gas cartridge, or butane fuel source, TSA allows them in carry-on luggage only, not checked baggage.

The safest packing choice is simple. Put a corded flat iron wherever it fits best, but pack cordless and butane models in your carry-on with the heating element covered and the device protected from accidental activation. Spare gas refills are not allowed.

Hair Straighteners on Planes: Quick Rules

• Corded hair straighteners: Allowed in carry-on and checked luggage.
• Cordless lithium-battery hair straighteners: Allowed in carry-on luggage only under TSA rules.
• Butane or gas-powered hair straighteners: Allowed in carry-on luggage only in the U.S., with the heating element covered.
• Spare gas or butane cartridges: Not allowed in carry-on or checked luggage.
• Safety cover: Cordless models need a safety cover over the heating element.
• Accidental activation: Pack cordless tools so they cannot turn on inside your bag.
• Battery size: Most consumer cordless straighteners are under FAA lithium battery limits, but larger batteries may need airline approval.

For most travelers, the rule is easy: a normal plug-in flat iron can fly in either bag. A wireless flat iron should go in your carry-on.

Can I Bring a Hair Straightener in Carry-On Luggage?

Yes. You can bring a hair straightener in carry-on luggage. TSA allows both corded and cordless flat irons through the checkpoint, but cordless models have extra packing requirements because they contain a battery, gas cartridge, or fuel source.

A corded hair straightener can usually stay inside your carry-on during screening. TSA does not require you to remove it the way you would remove a laptop in a standard screening lane. If your bag is pulled aside, it is usually because the tool or cord needs a closer look on the X-ray, not because flat irons are banned.

For cordless models, carry-on is not just allowed, it is required in the U.S. The reason is practical: if a battery or gas-powered device overheats, smokes, or turns on by accident, the cabin crew can access it in the cabin. They cannot do that if it is inside the cargo hold.

Can You Pack a Hair Straightener in Checked Luggage?

You can pack a corded hair straightener in checked luggage. TSA lists corded electric hair straighteners and curling irons as allowed in checked bags, as long as they do not also include batteries or gas cartridges.

You should not pack a cordless lithium-battery, gas-powered, or butane-powered hair straightener in checked luggage for U.S. flights. TSA’s cordless flat iron listing says these models are allowed in carry-on bags and not allowed in checked bags.

Even when a corded straightener is allowed in checked baggage, carry-on is often the better choice if you have room. Styling tools can crack, bend, or get damaged when checked luggage is thrown around during handling. If your bag gets delayed, you will also lose access to the tool at your destination.

Corded vs Cordless Hair Straighteners

The important question is not whether the tool is a straightener, flat iron, or styling iron. The important question is how it is powered.

If you are unsure which type you own, check the product label or manual. Words like “cordless,” “rechargeable,” “lithium-ion,” “butane,” “gas,” or “cartridge” mean you should treat it as a special-case item.

Lithium Battery Hair Straighteners

Cordless rechargeable straighteners usually contain lithium-ion batteries. TSA requires cordless lithium-battery hair straighteners to travel in carry-on luggage only. The heating element needs a safety cover, and the device needs to be packed so it cannot turn on by accident.

The FAA also limits lithium batteries by watt hours (Wh). Most small consumer hair tools fall under 100 Wh, which is the normal limit for lithium-ion devices. Larger batteries from 101 to 160 Wh may require airline approval, and batteries over 160 Wh are generally forbidden on passenger aircraft.

If your straightener only lists milliamp hours (mAh), the rough conversion is:

mAh x volts / 1000 = watt hours

For example, a 5,000 mAh battery at 3.7 volts is about 18.5 Wh. That is well below the 100 Wh limit. If the number is close to or above 100 Wh, contact your airline before flying.

Butane and Gas-Powered Hair Straighteners

Butane hair straighteners are less common now, but they still exist. TSA treats them differently from regular corded tools because they contain fuel. For U.S. flights, cordless gas or butane-fueled hair straighteners are allowed in carry-on bags only and not in checked luggage.

The heating element must be covered, and the tool must be packed so it cannot accidentally activate. Spare gas refills or butane cartridges are not allowed in either carry-on or checked baggage. If you need refills, buy them after you land.

Do not confuse butane hair tools with aerosols like hairspray or dry shampoo. They are regulated differently. If you are packing styling products as well, review the liquid and aerosol rules before placing them in your carry-on.

International Flight Rules

For flights departing from the U.S., TSA and FAA rules are the main rules to follow. International rules can be stricter, especially for butane tools and removable lithium batteries. Some countries and airlines allow certain gas-powered hair tools in checked baggage with conditions, while others ban them completely.

Because the rules vary, use this practical approach for international trips:

• Pack a regular corded dual-voltage straightener when possible.
• Avoid butane straighteners for international travel unless your airline confirms they are allowed.
• Keep lithium-battery styling tools in your carry-on.
• Check whether your destination uses 110V, 220V, or 240V power.
• Bring the right plug adapter, but remember that an adapter does not convert voltage.

Voltage matters more than many travelers expect. A U.S.-only 120V flat iron can burn out if plugged into a 220V or 240V outlet overseas. Look for “100-240V” on the label if you want a straightener that works internationally.

How to Pack a Flat Iron Safely

A hair straightener is allowed, but it can still damage your bag if you pack it carelessly. Heat, cords, and ceramic plates all need a little protection.

• Let it cool completely. Do not put a hot flat iron directly into luggage.
• Use a heat-resistant pouch. A silicone sleeve or heatproof pouch protects the plates and surrounding items.
• Do not tightly wrap the cord. Loose wrapping helps prevent cord damage near the hinge.
• Cover cordless heating plates. TSA specifically requires a safety cover for cordless models.
• Prevent accidental activation. Lock the switch, use the travel cover, and avoid packing anything that presses the power button.
• Keep batteries accessible. Battery-powered tools are better in carry-on luggage where they can be inspected if needed.

If you are also packing other hair tools, the rules are similar but not identical. We have separate guides for curling irons on planes, hair dryers on planes, hair dye on planes, and hair gel on planes.

Official Sources to Check Before You Fly

TSA has separate listings for corded hair straighteners and cordless hair straighteners. For battery limits, check the FAA’s Airline Passengers and Batteries guidance. If your tool is unusual, expensive, or powered by butane, also check with your airline before travel.
