What Are Auto Shut-off Hair Straighteners & How Do They Work?

Auto shut-off hair straighteners are no different from standard straighteners. However, they have an additional feature that turns off the device when left unattended for a specific time.

Such hair straighteners have heat and motion sensors in their plates. When the hair straightener is not in use, the sensors are triggered, and the device shuts off. The automatic sleep time varies from device to device. While some flat irons let you set the time limit, some have a fixed timing that you cannot alter.

You can easily find hair straighteners that shut down in just 15 minutes of inactivity. And after shutting off, they start cooling down. So, your house remains safe!

Why Use Auto Shut-Off Hair Straighteners? What Are The Benefits?

Though hair straighteners are tiny hair styling tools, they can reach impressively high temperatures. Besides, on average, flat irons take around 45 minutes to cool down completely.

And when you forget to unplug your straightener after using it, it can lead to an electrical short circuit and eventually burn down your entire house.

On top of that, by bringing home a hair straightener that turn off automatically, you can keep yourself worry-free even when you forget to turn it off. Simply saying, if you are always in a rush, such flat irons will give you peace of mind.

Although automatic shutoff is such an essential feature, unfortunately, not all flat irons offer this functionality. Most of the brands offer this feature in only a few models.

However, those models that come with automatic sleep functionality have it mentioned under their features list. So, before purchasing your next flat iron, scroll your eyes past its features list. And make sure you get one that shuts off automatically.
