Without a doubt, the best hair straightener I’ve ever tried. I have tried so many different hair straighteners since I started my blog, but the T3 SinglePass X Hair Straighteners have really blown me away…

It is the speediest, most powerful, award-winning technology from T3 to date. Step into the fast lane.

T3 Tourmaline® SinglePass™ Technology

Digital technology so advanced, it takes the conventional styling iron into the realm of artificial intelligence.

  • A microchip brain in the iron constantly measures and adjusts the temperature of the plates for accurate, consistent heating while styling.
  • Other irons test the plate temperatures in intervals causing heat fluctuation, which can lead to damage due to over-styling.
  • T3 SinglePass irons smooth and style hair in one quick pass, working fast to deliver long-lasting, professional results with a healthy, shiny finish.

This straightening iron was created with demanding hair in mind, and it passed all of our tests.
