Jon Renau Infrared Duo Styler: A Flat Iron That Styles and Sets in One Step

The Jon Renau Infrared Duo Styler is a flat iron made for alternative hair, including human hair wigs and toppers, heat-friendly synthetic fiber and your own biological hair. It pairs infrared heat with a built-in cooling fan, so you can heat style a section and set it right away instead of waiting for the fiber to cool.

Jon Renau says the infrared heat helps lock in moisture, seal the cuticle and minimize protein loss for smoother, shinier results with less frizz. Curved ceramic plate edges let you straighten, flip or curl with the same tool, and the newest version adds a temperature lock and a longer power cord for more control while you style.

7. To turn it off, press the fan button to stop the fan, then hold the power button twice (once to unlock the temperature and once to turn off the styler) and unplug.

Jon Renau Infrared Duo Styler FAQ

Can I use the Infrared Duo Styler on a synthetic wig?
Only on heat-friendly synthetic fiber, such as Jon Renau's heat-friendly wigs and toppers, at 285°F or lower. Do not use it on traditional synthetic fiber, which can melt or frizz with heat.

What temperature should I use on a heat-friendly wig?
Never go above 285°F with this styler on heat-friendly fiber. Jon Renau recommends styling heat-friendly synthetic at 270°F to 280°F. See our Jon Renau heat-friendly wig care guide for more.

What does the cooling fan do?
The fan cools each section as soon as you style it, which sets the curl or smooth finish in place. That means no more curl, clip and cool routine, less time under heat and faster results.

Can I curl with the Infrared Duo Styler?
Yes. The curved plate edges let you curl, flip or straighten with one tool.

Is the Infrared Duo Styler dual voltage?
Yes. Jon Renau says the Infrared Duo Styler is dual voltage, so it works globally. It comes with a U.S. plug, so use a plug adapter when traveling outside the U.S.
