Do Hair Straighteners Automatically Turn Off? (Answered)

If you’ve recently started using hair straighteners regularly, you may be wondering, ‘do straighteners turn themselves off’? It’s easy to forget to turn the straightener off when you’ve finished with it so this is an important question.

Do Hair Straighteners Automatically Turn Off

Luckily, almost all newer versions of hair straighteners have an automatic shut-off feature built-in which is a great safety feature.

You will find that the more expensive, professional-grade hair straighteners come with automatic shut-off systems while unfortunately, the cheaper versions, usually found at drugstores, come without an automatic shut-off.

So, if forgetting to turn the straightener off is a problem for you, it may be smart to invest in a pricier model that comes with an auto shut-off feature. 

Why Automatic Shut-off is an Important Feature

Having an automatic shut-off feature on your hair straightener may not seem all that important, but it is.

The most important reason why you would want an automatic shut-off feature is it is the best way to prevent a house fire when it comes to hair straighteners.

Forgetting to turn these devices off can lead to them overheating and catching fire, putting you, your family, and your home at risk. 

Another reason it’s good to have an auto shut-off feature is that it can help you not to worry about whether or not you shut your straightener off.

People who forget to turn these devices off are already out of the house by the time they remember, and they either have to go back to check or they continue to worry throughout the day.

Having them automatically shut off can alleviate stress and worry, keep your furniture safe, and reduce the risk of a house fire starting.

Other Safety Precautions 

If your hair straightener does not have an automatic shut-off, then you should take extra caution to remember to unplug and turn off your styling tool when you’ve finished using it.

You can also purchase a heat-resistant mat or stand to place your straightener on. This will also help protect your furniture and anything that may be placed around the straightener.  

How to Tell if Your Straightener Has an Auto Shut-off

Do Hair Straighteners Automatically Turn Off

If you already own a straightener and you still have its packaging or user manual, you can find this information there.

If you do not have the packaging or user manual but know the make and model of your straightener, you can find this information by doing a quick Google search.

However, if you do not have the packaging or user manual, and you do not know the exact model of straightener you have, then your only option is to test it for yourself by leaving it on for an hour and see if it is automatically shut off.

If you are purchasing a new straightener, then you can find this information listed on the packaging or on the online store’s product information.

Frequently Asked Questions

What Happens If I Accidentally Leave a Straightener On?

Aside from the obvious fire risk, leaving a straightener on and unattended can cause burn marks on the wood and anything around it, causing significant damage to your property and items. There is also the chance of damage occurring to the straightener itself, making the need for a replacement happen sooner than need be.

How Long Does it Take for a Straightener to Automatically Shut Off? 

It varies. However, most hair straighteners that have an automatic shut-off system will shut off within an hour of being left unattended but some come with a system that automatically shuts off after 15 minutes of non-use. 

How Does the Automatic Shut-off Work?

Straighteners that come programmed to automatically turn off when not in use have built-in motion sensors located in the plates. When these sensors no longer detect any movement or use, the motion sensors will cause the automatic shut-off feature to kick on and the straightener will put itself to sleep or turn itself off.
