Can You Bring a Hair Dryer on a Plane?

Yes — corded hair dryers are allowed in carry-on luggage and in checked luggage. No major aviation security authority restricts hair dryers. They pass through X-ray screening without issue and are not subject to any size, wattage, or capacity limits at the checkpoint.

The more relevant questions for most travelers are about voltage compatibility and whether it is worth the weight.

Security Rules

Hair dryers are permitted by:

• TSA (United States) — allowed in carry-on and checked bags
• UK CAA — allowed
• EU aviation security — allowed
• Australian security — allowed

There is nothing about a hair dryer that triggers the rules covering liquids, sharp objects, or battery-powered electronics. They are straightforward appliances with no special handling requirements.

Voltage: The Practical Problem

This is where most international travelers run into trouble. Hair dryers are high-wattage appliances (typically 1200–2000W), and voltage matters enormously.

Voltage label on dryer	Where it works
120V only	United States, Canada, Mexico, some Caribbean islands
220-240V only	Europe, UK, Australia, most of Asia, Africa, Middle East
100-240V (dual voltage)	Worldwide — works on any outlet with the correct plug adapter

Using a 120V dryer on a 240V outlet without a converter will damage or destroy it. The motor will overheat instantly. Some dryers have a thermal cutoff that trips before burning out, but many will simply fail.

How to Check Your Hair Dryer's Voltage

Look at the label on the handle or near the plug. It will say something like:

• 120V ~ 60Hz — single voltage, North America only
• 220-240V ~ 50Hz — single voltage, Europe/Asia only
• 100-240V ~ 50/60Hz — dual voltage, works worldwide

If it says 100-240V, you need only a plug adapter (to fit the local socket shape), not a voltage converter. If it says a single voltage, you need a converter — which is bulky and defeats the purpose of a compact travel dryer.

Best Approach: Buy a Dual-Voltage Travel Dryer

Compact travel hair dryers designed for international use are dual-voltage by design. Popular options include the Conair 1600W Travel Hair Dryer and the BaByliss Nano, both of which fold compactly (around 300-400g) and work on any outlet with an adapter. These take up roughly half the bag space of a full-size dryer.

Cordless and Battery-Powered Hair Dryers

Battery-powered and cordless hair dryers exist but remain a niche product. Most use lithium-ion battery packs.

Rules for battery-powered hair dryers:

• The device itself can go in carry-on or checked luggage
• The lithium-ion battery must travel in carry-on (checked-luggage lithium battery rules apply — below 100 Wh is permitted in carry-on; over 100 Wh requires airline approval)
• Most cordless hair dryer batteries are small (under 100 Wh) and well within standard limits

Check the battery's watt-hour rating printed on the cell or in the product manual before packing.

Butane Hair Dryers: Banned

Butane-powered hair dryers — which heat air by burning butane gas rather than using electricity — are banned from both carry-on and checked luggage. The butane canister is classified as a flammable gas, which is prohibited in aircraft by ICAO rules.

This ban covers:

• The complete butane hair dryer unit
• Spare butane canisters sold separately
• Any other butane-powered heating appliance

If you own a butane dryer, leave it at home. There is no way to take it on a commercial flight.

Checked Luggage

There is no restriction on corded hair dryers in checked luggage either. If you are travelling with a full-size 2000W salon dryer, it can go in your checked bag. The only consideration is weight — full-size dryers can be 600g–1kg, which eats into your luggage allowance.

Is It Worth Packing?

Before adding a hair dryer to your bag, consider:

• Hotel amenity — most mid-range and above hotels include a hair dryer. Check the property's amenities on the booking page. If it's listed, you do not need to pack one
• Weight — even a compact travel dryer is 300-400g. On weight-restricted hand luggage fares, this matters
• Voltage adapter — a dual-voltage dryer needs only a plug adapter (lightweight, cheap). A converter for a single-voltage dryer is heavy and expensive
• Destination stores — if you are staying for several weeks, a cheap local dryer bought at a supermarket or pharmacy on arrival is often the most practical solution

For most travelers on trips of a week or less, checking the hotel amenities and leaving the dryer at home is the simplest path.
