Yes, you can bring a hair straightener on a plane. Wired flat irons fly in carry-on or checked. Cordless lithium-battery and butane-powered models have to go in carry-on (with restrictions) and aren’t allowed in checked baggage in most countries.
Here’s the full breakdown of the rules across major regions and how to actually pack a flat iron without losing it at security.

TSA Rules for Hair Straighteners
The TSA allows wired plug-in hair straighteners in both carry-on and checked baggage with no restrictions. No quantity limit, no special packing rules.
Cordless and butane straighteners are different:
- Cordless rechargeable (lithium battery): Carry-on only. Battery must be under 100 Wh (under 160 Wh with airline approval). Pack with a heat-shield cover and store in a way that prevents accidental power-on.
- Butane (gas-powered): Carry-on only. The straightener itself can fly with one cartridge installed. Spare butane cartridges are banned in both carry-on and checked.
- Damaged or non-functional devices: Banned. TSA may ask you to power on a battery-powered device to confirm it works. A dead device can be confiscated.
Rules in Other Countries
Wired plug-in straighteners are allowed everywhere. The variation is in how each country handles butane and lithium-battery models.
Canada
Wired: allowed in both. Butane: one straightener per passenger; the device alone goes in carry-on, while the device + cartridge can go in checked baggage with a heat-shield cover. Spare cartridges banned. Lithium battery: under 100 Wh allowed in both carry-on and checked, 100-160 Wh requires airline approval.
Hair straighteners typically list battery capacity in mAh. Convert to Wh by multiplying mAh × volts ÷ 1000.
Example: the Zavarea cordless hair iron has a 12,800 mAh battery at 9V, which works out to 115.2 Wh (12,800 × 9 ÷ 1000). That requires airline approval. Most consumer cordless straighteners are well under 100 Wh.
Europe and New Zealand
European flights and New Zealand follow similar rules. Wired: allowed in both. Butane: one per passenger, both carry-on and checked allowed with heat-shield cover, no spare cartridges. Lithium battery: under 100 Wh allowed in both, 100-160 Wh needs approval, over 160 Wh banned.
United Kingdom
Wired: allowed in both. Butane: allowed in carry-on and checked with heat-shield cover, no spares. Lithium battery cordless: requires airline approval, and if approved, the battery must be removed from the device and its terminals isolated.
Australia
Wired: allowed in both. Butane: checked baggage only and requires airline approval; heat-shield cover mandatory; no spare cartridges. Lithium battery cordless: must be declared at the airport. Allowed in carry-on or checked with the battery removed and terminals insulated.
China
Wired: allowed in both. Butane: banned in both carry-on and checked baggage in China. Lithium battery: under 100 Wh allowed in both, 100-160 Wh needs airline approval, over 160 Wh banned.
India
Wired: allowed in both. Butane: banned in both carry-on and checked. Lithium battery: under 100 Wh allowed in both, 100-160 Wh requires approval. Switch off the device and protect the heating element from accidental activation.
Frequently Asked Questions About Bringing Hair Straighteners on Planes
Are wired hair straighteners allowed on planes?
Yes, in both carry-on and checked baggage with no restrictions. Wired electrical appliances aren’t considered dangerous when not connected to power, so TSA and most international authorities allow them freely.

What’s the best hair straightener for travel?
The Vanessa Pro is a solid pick. Works as both a flat iron and curling iron, has a swivel cord, dual voltage (so it works internationally without frying), and automatic shut-off. Compact enough for a carry-on without taking up serious space.
Are cordless rechargeable hair straighteners allowed?
Yes, with restrictions. In the US, TSA allows cordless lithium-battery straighteners only in carry-on baggage. They’re banned from checked. Some other countries (the EU, Canada) allow them in both, but in carry-on is always safer.
Battery capacity rules:
- Under 100 Wh: Always allowed (with country-specific carry-on/checked restrictions)
- 100-160 Wh: Requires airline approval before flying
- Over 160 Wh: Banned everywhere
Convert mAh to Wh: mAh × volts ÷ 1000 = Wh. Example: 5,400 mAh × 9V ÷ 1000 = 48.6 Wh (well under the limit).
Pack the device switched off, with a heat-shield cover over the plates, and protected from accidental activation. Have it charged enough to power on if requested at security.
Are butane hair straighteners allowed?
Depends on the country. Quick rundown:
- US, UK, Australia: Allowed (carry-on only in the US, both in UK; checked-only with approval in Australia)
- EU, Canada, New Zealand: One per passenger, both carry-on and checked allowed
- China, India: Banned entirely
In every country that allows them, spare butane cartridges are banned. Buy refills at your destination if needed. The straightener itself must have a heat-shield cover and be packed to prevent accidental activation.
Always confirm with your airline before flying. Butane rules are the most country-specific of any styling tool category.
Do I have to take the hair straightener out at security?
Wired hair straighteners can stay in your bag (no battery, no heat element when unplugged). Cordless lithium-battery models should come out and go in a separate bin like a laptop. TSA PreCheck members can leave everything in.
Should I pack a flat iron in carry-on or checked?
Carry-on. Wired models work in either, but checked baggage takes a beating and electronics can break. Cordless and butane models are required to go in carry-on per TSA rules.
How should I pack my hair straightener?
Use a heatproof pouch or silicone sleeve over the plates. This protects the heating element and prevents accidental activation if the power button gets pressed in transit. Wrap the cord around the body. Place the whole thing in the middle of your bag, surrounded by clothes.
Will my flat iron work internationally?
Only if it’s dual voltage. Standard US flat irons run on 110V. Plug one into a 220-240V European or Asian outlet and it will burn out in seconds, even with a plug adapter. Look for “100-240V” on the label. If it says “120V only,” leave it home and use the hotel’s or buy a dual-voltage travel iron.
Can I use my hair straightener during the flight?
No. Heat-generating devices are banned in flight on every commercial airline. Even if your seat had an outlet, cabin crew won’t allow it. Style your hair before boarding.
Are other hair styling tools allowed?
Yes, with the same general rules:
- Wired hot combs, hot rollers, electric hot air brushes: Both carry-on and checked, no restrictions.
- Cordless battery-powered styling tools: Carry-on only. Same lithium battery rules apply.
- Butane styling tools: Same butane rules as straighteners.
- Combs, brushes, bobby pins: Allowed if plastic and without sharp edges.
- Hairspray, hair gel, dry shampoo, shampoo: Carry-on must follow the 3-1-1 liquids rule (3.4 oz containers, quart bag). Checked allows up to 18 oz containers for hairspray and dry shampoo.
- Hair clippers: Allowed in both, agent’s discretion at the checkpoint.
