Having the correct voltage is essential when using hair tools abroad. Discover why a dual voltage flat iron is the best travel hair straightener for international travel, plus our top recommendations!

Why You Need a Dual Voltage Flat Iron for Travel

A sleek, polished hairstyle instantly elevates any travel outfit, but full-size straighteners are bulky, heavy, and risky to use overseas. A dual voltage flat iron is designed to work safely with international electrical systems, making it a must-have for global travel.

Unlike regular hair straighteners, dual voltage flat irons can switch between 110–120V and 220–240V, allowing you to style your hair anywhere, from hotels and Airbnbs to cruise cabins, without damaging your tool or your hair.

Key Benefits of a Dual Voltage Flat Iron

Works worldwide with international voltage compatibility
Compact and lightweight for carry-on packing
Straightens, waves, or curls hair
Saves time, space, and packing stress

I never leave home without my T3 dual-voltage straightener, I love how it makes my hair look travel-ready!

How to Choose the Right Travel Flat Iron

The right travel flat iron should suit your hair type, travel style, and luggage space. Focus on these key features when choosing one for your trips:

Dual Voltage: Essential for international travel. Look for flat irons that work on both 110–120V and 220–240V, and remember to use a travel adapter for the plug type.

Plate Size & Material: Ceramic or tourmaline plates reduce frizz, while titanium heats quickly for coarse hair.
- Small plates (≤1″) are best for short hair and curls
- Medium plates (1–1.5″) work for most hair types
- Wide plates (2″+) suit thick or long hair

Heat Settings: Adjustable temperatures help protect your hair:
- Low for fine or damaged hair
- Medium for normal hair
- High for thick or curly hair

Size & Portability: Compact, lightweight designs are ideal for carry-on packing. For minimal bulk, choose a flat iron under 8 inches long.

Styling Versatility: Many travel flat irons can straighten, curl, or wave hair. Rounded edges or 2-in-1 designs reduce the need to pack extra tools.

Safety & Budget: Auto shut-off and heat-resistant cases are travel must-haves. Options range from premium brands to budget-friendly models that still perform well.

Quick Takeaway: The best travel flat iron combines dual voltage, the right plate size, adjustable heat, portability, and styling flexibility to keep your hair looking polished wherever you go.

Travel Straightener vs Travel Flat Iron

The terms “hair straightener,” “straightener,” and “flat iron” all mean the same thing , they are just words used by different countries. For example, in the US, we may use flat iron or hair straightener, but in the UK, they only use hair straightener. The terms all refer to a hair tool that is used to flatten or straighten hair with heat.

What Does Dual Voltage Mean?

Some electronics are designed to work in multiple countries and are labeled as dual voltage. For hair tools like flat irons, this means they can safely operate on both 110–120V (used in the US and Canada) and 220–240V (used in Europe, Asia, and many other regions).

Dual-voltage flat irons are ideal for travel because they can be used at home and abroad without risking damage to the tool, or your hair. Many travel straighteners automatically adjust to the correct voltage, while others require you to switch the voltage manually using a small toggle or selector on the device.

If a flat iron is not dual voltage, it’s best to leave it at home, as plugging it into a higher-voltage outlet can cause overheating or permanent damage. Unlike phones and laptops, which usually auto-adjust voltage, hair tools require special attention.

All of the dual-voltage flat irons featured in this guide are designed for international use, making them safe and reliable travel companions when paired with the correct plug adapter.

Read our guide that explains how voltage converters and travel adapters work!

Why Do I Need a Dual Voltage Flat Iron for International Travel?

Voltage refers to electricity; different countries have different types of electricity. This means that your electronics are the same voltage as the country in which you bought them, so if you take them to another country, they may not work.

For example, in the US, we use 110-120V; whereas in Europe, they use 220-240V. If we plug our electronics into each other’s outlets, they can blow a fuse and stop working. In some cases, they can even fry your hair.

Visit this website for a full list of voltage by country.

NEWVANGA International Universal All in One Travel Adapter

Your travel straightener needs to have two things in order to work in other countries:

Hair tools such as blow dryers, wands, curling irons, and your travel flat iron use a large amount of electricity, so it’s particularly important that they are used with the correct voltage.

Some travel flat iron options are designed so they can be used in different countries. This means they’ll be labeled as a “dual voltage flat iron.”

Travel adapter for travel straightener tools and other electronics:

Even if your hair tools are dual voltage, you still will need a travel adapter. A travel adapter enables you to plug your electronics, such as a travel flat iron, into international outlets. Not all countries use the same type of plug, so I recommend you buy an international adapter like this. Read more about the best travel adapter here.

Best Travel Straightener to Use in the USA

If you’re from the US and traveling within the US, then you don’t need to have a dual voltage flat iron or travel straightener. However, you might want to save space by choosing a travel flat iron instead or one of the smaller options featured in the article.

If you’re traveling to the US from outside of the US, then you should use a dual voltage flat iron and make sure to switch to the 110V/120V before using it.

How to Choose a Travel Straightener for Europe

If you’re from the US and traveling to Europe, Asia, Africa, or the South Pacific, including Australia and New Zealand, then a dual voltage flat iron is absolutely essential. If the one you use at home has the dual voltage feature, then you can also use it on your travels, too.

Remember to switch your travel flat iron to 220V/240V when you arrive to your destination!
