What to do if the Xiaomi Cordless Hair Straightener Brush does not work after turning it on?

If your Xiaomi Cordless Hair Straightener Brush isn't working after turning it on, follow these steps to troubleshoot:
1. Listen for a sizzling or hissing sound, which indicates that the negative ion function is working. If you don't hear it, there will be an issue with the device;
2. Verify if the temperature level indicators are flashing. By default, the device starts at level 2 when powered on. Flashing indicators mean the device is in the heating process;
3. Check the appearance of the device for any signs of drops, impacts, or other physical damage that will have affected its functionality;
4. If none of the above issues apply and the device still doesn’t work, please reach out to the after-sales service for further assistance.
