The Upgrade BIOINFRARED Professional Hair Straightener is an ideal styling tool for those with fine, color-treated, or fragile hair who need a salon-grade finish without excessive heat damage. By utilizing advanced Bio-Infrared technology to heat the hair from within while sealing cuticles, it preserves moisture and promotes long-lasting shine. While it offers professional-level performance and wide plates for efficient styling, users should be mindful that the high-performance heating elements reach temperatures up to 230 °C, requiring careful selection of heat settings to prevent overheating sensitive hair types.

Yes, the Bio-Infrared technology is designed to preserve moisture, making it much safer for treated hair than traditional flat irons, provided you use the lower temperature settings.
The extra-long, wide plates are primarily optimized for straightening, but the rounded edges can be used to create soft waves or flips if handled with care.
Thanks to the titanium heating elements, the device heats up very quickly, usually reaching full operating temperature in under a minute.
This coating produces negative ions that help close the hair cuticle, resulting in smoother, shinier hair while neutralizing static electricity.
Please check the label on your specific device, as voltage compatibility can vary by region; typically, professional tools are designed for standard household outlets.
Verify the power plug is fully seated in the outlet and check that the digital display is active. If the display is off, ensure the wall outlet is providing power.
Reduce the temperature setting via the digital control. For fine or damaged hair, start at the lowest setting (130 °C) and increase only if necessary.
The unit likely entered the automatic sleep mode due to one hour of inactivity. Press the power button to reactivate the heating process.
To begin, plug the straightener into a standard electrical outlet and use the digital interface to select your desired temperature. Allow the plates to heat fully before beginning styling; the device will reach its target temperature quickly due to the titanium build.
