Using hair straighteners in Denmark

Danish power outlet

Will my hair straighteners work in Denmark?

First check that your hair straighteners can work in Denmark:

  • If your hair straighteners can run using 230 volts or can support dual voltage (how to check) then you will only need to use a suitable power adapter listed on this page if the plug on your hair straighteners won't fit.

If not then:

  • Use a power converter [5] (or voltage transformer) - this enables you to use your existing hair straighteners and other applicances with a 230 volt Danish power outlet, however this is noticeably heavier, bulkier and more expensive than dedicated travel hair straighteners. A power converter changes the voltage but not the physical shape of the plug on your hair straighteners to fit in the types of power outlet used in Denmark, so check that your power converter [5] includes a suitable power adapter for Denmark otherwise you will need to purchase a seperate power adapter. Please be aware your own personal hair straighteners might not be suitable for travel and you could risk damage in transit.

Warning: If your hair straighteners won't handle 230 volts used in Denmark you run the risk of an electrical fire hazard, blowing a fuse or damage to your hair straighteners. Prior to using your hair straighteners in Denmark please read the instruction manual first to ensure safe operation.

Dual voltage hair straighteners

How can I tell if my hair straighteners are dual voltage?

Dual voltage hair straighteners

How can I tell if my hair straighteners are dual voltage?

An easy way how to tell if your hair straighteners will handle a dual voltage power outlet is to check for either a sticker or numbers printed on the handle or plug. This location might vary depending on the make and model of your hair straighteners and should also be written in the instruction manual or on the box. Some dual voltage hair straighteners can change automatically, however other straighteners will have a button or switch which allows you to toggle between different regions.

  • A specific number such as 110V indicates single voltage hair straighteners. If this number matches the 230 volts used in Denmark then you should be able to use your hair straighteners with a Danish power outlet.
  • A small voltage range with a dash such as 100-120V also indicates single voltage hair straighteners which can accomodate small voltage fluctuations. If the 230 volts used in a Danish power outlet falls within the range shown on your hair straighteners then you can use it in Denmark.
  • A larger voltage range separated with a dash or slash such as 100/240V indicates dual voltage hair straighteners capable of being used in Denmark or any other country.

Travelling to Denmark with hair straighteners

Can you carry on hair straighteners to Denmark?

Can you carry on hair straighteners to Denmark?

According to the TSA guidelines for hair straighteners [8] there are no restrictions when carrying mains powered hair straighteners in your hand luggage through airport security in the United States. The TSA recommends that you should verify that your airline who is taking you to Denmark will allow hair straighteners onboard and that they will fit in the overhead bin or underneath the seat of the aircraft.

Packing the hair straighteners in a dedicated heat resistant protective hot tools travel case [10] leaves them easily accessible by airport security, they can be packed away quickly avoiding a tangle of power cords in your carry on luggage (the TSA recommends wrapping cables tightly around hair straighteners). If you do intend to pack fragile or expensive hair straighteners in your hand held luggage then it is advisable to bring hard carry on luggage [11] as this offers the greatest protection against drops and knocks during transit.

Should I bring my domestic hair straighteners or travel hair straighteners to Denmark?

It is preferable to bring dual voltage travel hair straighteners instead of packing your existing domestic hair straighteners to Denmark as it is safer to assume that they will operate correctly with the 230 volt power outlets used with a Danish power outlet, provided that you use the correct plug adapter for Denmark. Please be aware that bringing your expensive domestic hair straighteners could put them at risk because of potential loss or damage in your check in luggage by an airport baggage handler in Denmark. The inconvenience and costs involved in repairing or replacing expensive specialised domestic hair straighteners in Denmark could outweigh the cost of purchasing cheap dual voltage travel hair straighteners [2] before setting off. If you intend to bring along your own personal hair straighteners in your luggage either slot them inside a boot or sneaker to protect from light damage, alternatively use a shockproof and heat resistant hot tools travel case [10] or heat travel mat for hair straighteners and curling irons [12] which also allows the hair straighteners to be transported immediately after use without risk of burning.

Power converters for Denmark

What is the difference between a plug adapter and a voltage converter for Denmark?

Voltage converter

What is the difference between a plug adapter and a voltage converter for Denmark?

A lightweight, small and cheap power adapter (or plug adapter) will change the shape of the plug on your hair straighteners to slot into a power outlet found in Denmark, whereas a heavier and more expensive power converter [5] will convert a 230 volt Danish power outlet to work with non-230 volt hair straighteners.

Will a power converter work with a normal hair straighteners in Denmark?

A suitable voltage transformer [5] (or power converter) allows hair straighteners using a different voltage to operate with the 230 volt power outlet used in Denmark. A power converter is more suitable for travellers who wish to bring along their own hair straighteners, however it can be a lot less expensive to purchase dedicated dual voltage travel hair straighteners [2] than it is to purchase a power converter. A power converter is also significantly bulkier and heavier than travel hair straighteners making a power converter less suitable when packing in luggage.

Hair straightener safety

Are hair straighteners dangerous?

The temperature of the ceramic plates used in hair straighteners can reach over 200 degrees with the potential to burn hair, skin, and even start a fire if not used correctly. According to figures from Leicestershire Fire and Rescue Service electrical beauty products have been responsible for an estimated 650,000 fires in the United Kingdom alone.

How can I minimise risk using hair straighteners?

How can I minimise risk using hair straighteners?

  • Skin protection: Wear heat resistant gloves [13] during styling to protect hands from heat.
  • Children's protection: With 10% of children's burns being caused by hair straighteners it is recommended to look for hair straighteners which include a heat resistant end cap [16] to keep the plates closed shut when not in use, making it easier to store out of reach of children.
  • Luggage protection: Placing hair straighteners directly into luggage without allowing them to cool down can risk damage to clothes and heating up combustible or flammable packed items. If your hair straighteners weren't supplied with a heat protective cap then wrap them in a heat mat [12] or use a hot tools travel case [10] to pack them into luggage whilst warm. A travel case will also keep expensive hair straighteners protected from damage during transit.
  • Hair protection: Applying a heat protectant spray [14] prior to using hair straighteners is essential to prevent burning, as well as using the correct technique for your hair type - read our guide on how to use hair straighteners for comprehensive information.
  • Fire protection: It can take up to 40 minutes for hair straighteners to cool down so resting your straighteners on a heat mat [12] could reduce the risk of setting fire to furniture. Forgetting to turn off hot domestic appliances can also cause fires. This risk can be reduced by using a model of straightener with a timer socket [15] which will turn itself off automatically after a certain length of time, you can also add this feature to any basic straighteners by using a timer socket in a power outlet.

How can I add a safety timer to my existing hair straighteners?

How can I add a safety timer to my existing hair straighteners?

1 in 12 owners of hair straighteners admit to forgetting to turn them off after use, unless your hair straighteners have a built in automatic timer then leaving them on could potentially start a fire. However you can add this functionality to any model even if it doesn't have an integrated timer:

  1. Add an automatic timer to any hair straighteners by plugging them into a timer socket [15] then plugging the timer into a power outlet.
  2. Turn on the timer and use the hair straighteners as normal.
  3. After you have finishing using the hair straighteners turn off the power at the outlet.
  4. However if you forget to turn the power outlet off then the timer will automatically switch off the straighteners after a pre-set length of time. Depending on the model of timer this could be 15, 30, 60 or 120 minutes - ideally pick the shortest length of time possible.
  5. For added peace of mind use a power outlet splitter [17] to share the outlet from the timer with both your hair straighteners and a lamp. When the timer is running both the straighteners and the lamp will be turned on, making the lamp a clear indicator that the straighteners are still being heated. When leaving a room it is second nature to ensure all lights are turned off, if the lamp is still on then this acts as a reminder to switch off the straighteners.

How to treat a hot iron burn

If you accidentally burn yourself run cold water under your burn and if it is severe it is advised to seek medical attention from a doctor or hospital.

How to use hair straighteners in Denmark using a type K power adapter

The WikiConnections page showing how to power your hair straighteners in Denmark with a Type K travel charger.

  1. Check that the hair straighteners are either dual voltage travel hair straighteners [2] or is compatible with a 230 volt power outlet but if it doesn't then don't attempt these instructions as you may create an electrical fire hazard, damage your hair straighteners or blow a fuse. Before using a travel hair straighteners which can toggle between different voltages make sure the switch is set to accept 230 volts for use in Denmark - consult the user guide for more information on how to do this.
  2. You will need to buy a Type K plug adapter [4] if the type of plug used on your hair straighteners isn't the same shape as the plug outlet which is used in Denmark. The Type K plug adapter will help convert different plugs on appliances from other countries into an electrical outlet used in Denmark by changing the shape of the plug, however the adapter doesn't change the frequency or voltage of your hair straighteners to work with a 230 volt supply.
  3. Start the process by plugging the Type K plug adapter into the Danish power outlet. You can identify the wall outlet by the three holes forming an upside-down triangle pattern and the bottom hole appearing in a semicircle shape.
  4. Plug in the hair straighteners into the Type K plug adapter.
  5. Switch on the Danish power outlet.
  6. Your hair straighteners can now be powered on.
