3 Best Thermal Brush, Tested and Reviewed by WIRED (2025)

The Sutra infrared thermal style brush has a design similar to our superior choice, the WavyTalk, but instead of having two buttons, there is only one power button that you can maintain to light and deactivate, or type to switch between the five heat parameters. The button is easy to press while you use it, but it will not change the heat settings immediately, so it’s not the worst thing if you accidentally find yourself by accidentally pressing. It reaches the highest level of heat of the thermal brushes that I tested, which makes it a good choice for unruly hair that needs higher heat for the corral.

He does a good job smoothing my frizzy and curly hair after driving it, or reviving my DIY rash the next day after using a drying brush. I would prefer better controls, but it worked well for me for months. I have the option of 43 millimeters (which is about 1.7 inches), which was a beautiful oval size for a classic eruption look, but Sutra also has a smaller, rounded 32 mm brush ($ 110) If it’s no longer your style.
