Most hair straighteners on the market do have an automatic shutoff feature as a safety measure. This feature is designed to automatically turn off the straightener after a certain period of inactivity, typically ranging from 30 minutes to an hour. The purpose of this feature is to prevent overheating, potential accidents, and energy waste in case the user forgets to turn off the straightener after use.
However, it's worth noting that not all hair straighteners have this feature, so it's always advisable to check the product specifications or manufacturer's guidelines before using any hair styling tool.
