Best Dual Voltage Hair Straighteners


What’s the Advantage of a Dual Voltage Hair Straightener

Versatility is very important with any appliance and voltage is a big factor, especially if you’re going to use it for traveling. Different areas may require or limit you to use a certain voltage. Normally, hair straighteners come at 120V and you would have to use a transformer or an adapter for you to be able to use it on a 220V outlet.

This is not so much of an issue if you’re just going to use it in one place and the adapter that you need can just stay in place. But for those who need to bring the hair straightener with them, it will be a lot more convenient if the unit can be used with different voltages.

There are hair straighteners that can be used with different voltages, mostly from 100 – 240V. They may be a little more expensive but it could really benefit you in the long run.

In this guide, we will take a look at factors that make a good quality dual voltage hair straightener, and also compare different brands and models for you to know which best to choose. It would still depend on your overall needs and preferences.

How to Choose the Best Dual Voltage Hair Straighteners

So how do you know which dual voltage hair straightener is right for you? Here are some of the factors that you must consider. This also includes some necessary features that you want to make the most out of your money since dual voltage units cost more than others.

  • Automatic Voltage Adjustment

    Some advanced hair straighteners feature automatic adjustment on the voltage. This is a great feature in terms of convenience since you can do away with bringing the necessary adapters or having to be mindful of the voltage of whatever outlet you are going to use it with.

    Not all straighteners offer this feature and you must also watch out for the accuracy of the adjustment if ever.

  • Temperature Control

    It would be very helpful if the hair straightener features an adjustable temperature control setting. This is actually considered a must have, especially by professionals. If you’re going to get a dual voltage hair straightener, it might as well have a temperature adjustment feature.

    This is important in achieving a certain heat to suit your hair type and the styling that you want to do. Thick curly hair requires more heat for the hair to yield and straighten, while it is more advisable to use less heat on thinner hair.

  • Automatic Temperature Adjustment

    In?relation to temperature control, some hair straighteners even offer automatic heat adjustment. Most Ghd products are designed with the automatic temperature setting. The plates will heat up and cool down depending on the texture of the hair that they come in contact with.

    There is a disadvantage in this, though. Sometimes, those with unruly hair would need to set the heat manually because it may require more heat than what the chip in the hair straightener can determine.

  • Travel Pouch

    Since it is more likely that you will use a dual voltage hair straightener for traveling, it will be a great advantage if it also comes with a travel pouch or bag. Most slim models offer this feature. The BaBylissPRO Nano Titanium Mini comes with a travel pouch and it is also dual voltage.

  • Swivel Cord

    It would only be fitting that the hair straightener also comes with a swivel cord. If you travel a lot and would use the unit on different outlets, you would want the hair straightener itself to be easy to use.

    A swivel cord can prevent the hair straightener from being given tangled up as you style your hair, especially when reaching on the back portions of your head.

  • Automatic Power Off

    In relation to voltage, it is also important to protect your hair straightener by making sure that it does not overheat. Having an auto-off feature would prevent this from happening. Most units would turn off after about thirty minutes to an hour.


The price is always one of the most important things to consider in buying any type of hair straightener. With a dual voltage model, you must expect that it will be a little more pricey than the ordinary ones but you can be practical by making sure that you take note of the other considerations mentioned above.
