About T3 SinglePass and T3 Smooth ID
T3 is a U.S.-based brand blending advanced technology with beauty innovation. Known for creating high-performance tools, T3 aims to revolutionize hair styling with faster, smarter, and safer solutions.
Among their popular flat irons are the T3 SinglePass and T3 Smooth ID. While both are versatile tools designed to straighten, curl, or wave hair—and suitable for all hair types—they each bring unique features to the table.
T3 SinglePass
The T3 SinglePass is a sleek and compact ceramic flat iron engineered to style hair in just one glide. Thanks to its beveled ceramic plates and Digital T3 SinglePass® Technology, it distributes heat evenly to reduce damage and deliver shiny, frizz-free results. It’s ideal for those looking for quick, daily styling.
T3 Smooth ID
The T3 Smooth ID takes smart styling to another level. Featuring T3 HeatID® Technology, this advanced flat iron personalizes heat based on your hair’s texture, length, and color treatment. It also includes CeraGloss plates for smoother finishes and a built-in ion generator to minimize frizz.
Though similar in purpose, the Smooth ID is more tailored for those seeking precise control and minimal heat damage.

Plus, its ion generator helps lock in style and reduce frizz.
In short:
