Dyson Airsmooth Heat Brush, Tested & Reviewed in 2026


Granted, I didn’t clip up different layers to work through them one by one; I just tackled my entire head, section by section, swooping the brush up through the underlayers. But I’d argue that taking that approach makes my smooth, shiny and totally tangle-free results in that time even more impressive. 

Using and maneuvering the brush is simple. In addition to an on/off switch, there are only two buttons on the handle: one for heat, one for airflow, both of which can be toggled through to three settings (low, medium, high). You can also shut the heat off completely to allow for cool air to come through.

Now, as much as I love my air-dried waves, I don’t love the cloud of frizz that comes with them. Those wispy bits even appear after those rare times I do reach for a blowdryer. But with a little anti-frizz/heat protectant spray and my Dyson Airsmooth, I’ve finally been able to achieve a sleek finish. Notably, without having to sacrifice body and volume. Just as the brand promises, the teardrop barrel makes reaching my roots effortless—and not once do I feel even a tinge of singe on my scalp, even when the heat and airflow settings are both cranked up to high. 

On dry hair, the brush does struggle a bit to detangle my ends, but it still works wonders to smooth my style and reduce the frizz around my crown. For a quick refresh, it’s perfect. I also notice that my strands stay sleek for days after I style using the Airsmooth, with far fewer knots to brush out in the mornings.

My only complaint about using the Airsmooth is that I wish the handle were a bit slimmer. While I’m surprised by how little my arm fatigues while using it, my hand does get uncomfortable after a few minutes since it doesn’t fully wrap around the handle (then again, I might just have to work on my grip strength, something I’m sure will improve the more I used this bad boy).
