Can You Take a Flat Iron or Hair Dryer on a Plane?
Hey bestie! Packing for a trip and wondering whether your flat iron can come along in your carry-on? Good news: for most corded hair tools, the answer is yes. But there are a few things worth knowing before you zip up your bag, from cordless tool rules to the difference between a plug adapter and a voltage converter. Here's your no-stress guide.
Quick answer: Yes. In the US, the TSA allows corded flat irons, curling irons and hair dryers in both carry-on and checked bags. Cordless tools powered by butane or lithium batteries have extra restrictions, so check the TSA website before you fly. If you're traveling abroad, a dual voltage tool only needs a simple plug adapter, never a voltage converter.
Can you bring a flat iron on a plane?
Yes. Corded flat irons (hair straighteners) are allowed in carry-on and checked bags under TSA rules. The same goes for corded curling irons, curling wands, hot air brushes and hair dryers. Let your tool cool completely before packing it, and keep it in a heat-resistant pouch or case so the plates are protected.
Rules can change, and your airline or a security officer always has the final say, so it's smart to look up your specific item on the TSA website (or your departure country's aviation security site) before every trip.
Corded vs. cordless hair tools: what's allowed?
| Tool | Carry-on bag | Checked bag | Good to know |
|---|---|---|---|
| Corded flat iron | Allowed | Allowed | Let it cool and pack it in a heat-resistant case. |
| Corded curling iron or wand | Allowed | Allowed | Same as a flat iron; protect the barrel. |
| Corded hair dryer or hot air brush | Allowed | Allowed | A folding travel dryer saves space. |
| Cordless butane styling tool | Restrictions apply | Restrictions apply | Rules cover the tool, its safety cover and refills. Check the TSA website before you fly. |
| Cordless battery-powered tool | Restrictions apply | Restrictions apply | Lithium battery rules often differ for carry-on and checked bags. Check the TSA website and your airline. |
Because cordless tool rules depend on the type and size of the battery or fuel cell, we always recommend checking the TSA website before you fly instead of relying on a general rule.
Can you bring a hair dryer in a carry-on?
Yes, corded hair dryers are allowed in carry-on and checked bags. The bigger question is usually space and voltage. A compact, folding travel dryer is much easier to pack than a full-size dryer, and if you're leaving the US, you'll want a dryer that's dual voltage.
Dual voltage vs. voltage converters: what you actually need abroad
Outlets in the US supply about 110–120 volts, while many other countries use about 220–240 volts. Here's how to handle the difference:
- Dual voltage tool: designed to run on both ranges, usually listed as 110V–240V. You only need a plug adapter so the prongs fit the local socket. Never use a voltage converter with a dual voltage tool. Some tools switch automatically and some have a manual switch, so check your manual.
- 110V-only tool: designed for US-standard outlets. Plugging it into a higher-voltage outlet can damage the tool or create a safety risk. Many small travel converters aren't rated for high-wattage heat tools, so the simplest plan is to leave 110V-only tools at home and pack dual voltage ones instead.
Plug adapter vs. converter in one sentence
An adapter changes the shape of the plug; a converter changes the electricity. Dual voltage tools need only the adapter.
How to pack hair tools for a flight
- Check the rules. Look up each tool on the TSA website and check your airline's policies, especially for cordless tools.
- Check the voltage. Read the label or product page for "110V–240V" before traveling internationally.
- Cool completely. Never pack a warm tool.
- Wrap cords loosely. Tight wrapping can strain the cord where it meets the tool.
- Use a case. A heat-resistant pouch or travel bag protects plates and barrels.
- Pack liquids smartly. Heat protectant and serums in your carry-on need to follow liquids rules, so choose travel sizes or pack full sizes in checked bags.
- Bring the right plug adapter. Look up your destination's plug type before you go.

Cordless butane and battery-powered tools have restrictions that depend on the fuel cell or battery. Check the TSA website and your airline before you fly.
Do I need a voltage converter for my hair dryer?
Not if it's dual voltage. A dual voltage tool only needs a plug adapter, never a converter. If your dryer is 110V only, it isn't designed for 220–240V outlets, so pack a dual voltage travel dryer instead.
Can I bring heat protectant on a plane?
Yes, but liquids in your carry-on must follow liquids rules. Use a travel size or pack a full-size bottle in your checked bag.
Do hotels have hair dryers?
Many do, but power and quality vary. If you have thick or curly hair or wash your hair while traveling, a compact travel dryer is worth the space.
