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

The source infrared thermal styling brush has a design similar to our top pick, the weaver, but instead of having two buttons there is a single power button that you can hold on and turn off, or tap to toggle in five heat settings. It is easy to tap the button when you are using it, but it will not change the settings of heat right now, so if you see yourself pressing it accidentally it is not the worst thing. It reaches the highest heat level of the thermal brushes I have examined, it makes it a good choice for neutral hair that requires high heat to coral.

After I dry my jerk, curly hair it works a good to smooth it or I recover my DIY blout the day the next day I used a blow-shukno brush. I would like better control, but it has done well for me for months. I have a 43-millimeter option (which is about 1.7 inches), which had a great ovary size for the classic blout look, but the formula also contains a small, round 32 mm brush ($ 110) If it is more of your style.
