Thermal brush or hot air brush? Decode the blowout video.

By the Viral on TikTok editors · October 7, 2026

They can look similar on your feed, but drying and styling are different jobs.

Start with the job

A thermal brush heats its styling surface; a hot air brush moves heated air. Wavytalk describes its thermal brushes as tools for styling already-dry hair. If your goal is drying damp hair, compare a drying tool instead.

Match the video to the exact product

Check whether the creator is using Blowout Boost or another brush in the range. Compare the model, barrel size, plug and instructions on the actual listing. A brand name alone does not identify the tool in the video.

Fit the tool into your morning

Think about whether you want a dry-hair refresh, a shape at the ends or a drying routine. Count how many tools you already use and whether the new brush replaces a step. Save a tutorial that matches your length and technique rather than expecting every hair type to look like the demo.

Buy for the routine you have

Confirm the care directions and return terms before ordering. Follow the manufacturer’s instructions and start with its recommended settings for your hair. The goal is a tool you understand and enjoy using, not a drawer of almost-identical brushes.
