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.

Best Sighthill Ever!

I have just received this as a Christmas present and have used it for the first time today. I have been straightening my unruly frizzy overheated over treated hair for 25 years and have used many different brands but this is without a doubt the best product I have used. I am normally going over and over the same section of hair to try and get it straight and end up with frazzled dull dry hair. Not anymore! This heats up super fast and glides through my hair like a dream with the result of smooth straight glossy hair in record time. It took less than 5 minutes as opposed to the normal 20 minutes! I can't praise this product enough and will certainly recommend it. No more bad hair days.


I just received my t3 they are brilliant glides through my hair like a dream not fly away hair in sight unlike ghd they don't dry my hair out shine has surpassed my expectations audio/visual interface makes things so much more simple, delivery was quick too Thank you very much for your excellent service, i am one happy lady

Massive fan!

This is like something out of the future. I love it and is so fast !


Very easy to use and glides through the hair wonderfully. Unlike previous straighteners, this one doesn't dry my hair out and leaves it feeling great. The audio/visual interface is a great time saver and gets the straighteners ready for the perfect straighten.
