What is a Dual-Voltage Flat Iron?

We all know that a curling iron is what people with straight hair use to give it a curly look, while a flat iron or straightener is used by people blessed with curly hair, who wish to achieve a specific look with straight hair. But how are dual-voltage straighteners different from a regular flat iron?

A dual-voltage flat iron is more suitable for people who are traveling on and off as it comes with two different voltage options, making it more suitable for a variety of adapters. Those two voltage options are 110V-120V and 220V-240V.

Perks of Getting a Dual-Voltage Flat Iron

If you do decide to go with dual-voltage flat iron, then you must know there are multiple perks attached to these devices. Below are some of the perks of these flat irons:


These flat irons are pretty much compatible with each and every outlet, as they are dual voltage, so you don’t have to carry an extra adapter with you wherever you go.

Transformers or Converters

If you live in America and need to travel to Canada, instead of packing a transformer or converter for your trip, you can just carry your flat iron and the rest is taken care of. This even gives you more space in your suitcase, as it is less one thing to carry.

Not Missing Out

Just because it is a dual-voltage flat iron does not mean you have to compromise on its quality and features. It works in the same manner as any normal flat iron or straightener, so if you have any hesitation because you fear you might have to compromise on quality or features, don’t worry, you won’t be missing out. 

How to Choose a Dual-Voltage Flat Iron

Choosing a dual-voltage flat iron is no different than choosing a normal flat iron, straightener, or even a curling iron. All you have to do is consider a couple of factors to make sure you’re getting the best product in the market. To make your search is easy and to ensure that you choose the best unit, we are enlisting some of the main features you should look for in your flat iron.


Make sure that the flat iron you’re investing in is not made up of plastic, which will melt off easily. Obviously, you are going to use it more than once, so don't compromise on its material.


Always purchase a product with a warranty of at least a couple years of warranty. Otherwise, if it stops working, you have to pay to get it fixed or purchase a replacement.


Pay attention to the size of your dual-voltage iron. If you have voluminous hair, then a flat iron with more than a four-inch plate would be better for your hair. Otherwise, if you have plain, smooth hair, a two to three-inch plate would work easily on your hair. You must choose a unit with your hair texture and volume in mind.
