You already know Dyson changed the game for at-home blowouts everywhere when it launched the Supersonic dryer—and its new flyaway smoother attachment is now taking the brand's cutting-edge technology to the next level. This magnetic two-in-one attachment builds off the technology from its existing flyaway smoother, offering dual functionality to tame flyaways and smooth baby hairs in one go. Ideal for a sleek finish, the Dyson flyaway smoother is compatible with all versions of the Supersonic—including the original—and is currently sold separately for $60.
So how does this new attachment work? Well, it all has to do with the Coanda effect, in which rapid airflow clings to a surface. As the hot air wraps around the specially designed barrel, it carries the strands of hair with it to smooth out flyaways without any need for a clip, making it safer to use on dry and damaged hair. There are two surfaces here: One flat (for flyaways, as a finisher) and one bristled, which resembles a blow-drying brush to smooth damp or dry hair. To switch between the two, all you have to do is rotate the end cap of the attachment and listen for a click sound. You don't need to use an extra barrel brush with either side; simply lock in place the mode you want, turn the hair dryer on, then angle so that you can start from the roots and work your way down.
The brand says the bristled (or smoothing) mode works best on “straight or slightly wavy hair”—wet or dry—while the flat part (or flyaway mode) has to be used on dry hair and works best on naturally straight or wavy hair, or “straightened hair of any type.”
If you're still wondering how this new attachment differs from the original, remember this one does two jobs in one—drying hair but also creating a smooth finish—whereas the OG is meant only to complete your styling session by flattening out pesky flyaways.
A seamless blowout is always top of mind at the Glamour offices, which is why we had to put the Dyson Flyaway Smoother attachment to the test ourselves to see whether it's worth purchasing. Spoiler: It totally is.

I've been blow-drying my hair for as long as I can remember, but the Dyson Supersonic is the first tool that made me not hate the process. I have naturally thick, curly hair that falls somewhere between a 4A and 4B curl pattern, and blowing out my hair would easily take me over an hour. With the Supersonic, it takes me 30 minutes, tops. However, I would still find myself having to flatiron my roots at the end of each styling section, along with using the original flyaway attachment to smooth out the hairs near my hairline.
I was pleasantly surprised to see that this new attachment allowed me to ditch my flatiron after a blowout because it can access the roots so easily. While my roots were a little damp, I went through with smoothing mode to really get in there and make sure the curls flattened out—and boy, were they flat. I bleached my hair to achieve my latest honey blonde color back in May, and naturally, I've experienced some breaking near where I part my hair, so I have more flyaways than usual. Once I clicked the attachment into flyaway mode, I passed it along those hairs and they laid down almost immediately. To keep the style in place I used the Tigi Wax Stick to make sure they wouldn't budge throughout the day, and luckily, they stayed in place. As if I couldn't love my Supersonic enough, this new attachment just made me appreciate it so much more.

Is it too dramatic to say the Dyson Supersonic has forever changed the relationship I have with my hair? Thick and wavy with baby hairs in the front, I've come to accept frizz and flyaways as part of the equation when I give myself a blowout. Styling products help, but only so much—when the humidity is anything above 60%, my hair likes to inflate into a gravity-defying mane (not cute). So when I learned Dyson was releasing a new smoothing attachment for its most popular hair tool, I was viscerally compelled to try it. Cut to Thursday morning: I went on a run, showered, blow-dried my damp hair with the nozzle attachment with the heat and speed settings on three. (I applied my Sisley heat protectant cream on the midlengths and ends while my hair was still damp.)
After 15 minutes of blow-drying, I swapped the nozzle concentrator for the new attachment on “smooth” mode with the bristles. I start from the roots and went down to about halfway; because I was working close to the scalp, I decreased the heat and speed to the second heat setting (the highest felt too hot and powerful, even for my hair's thickness).
I was honestly amazed by how smooth it made my hair look with just a single pass. I then switched over to the flat part of the attachment for a final go. My hair looked so sleek and shiny I decided to skip the Rōz hair oil I normally use—and immediately slacked my coworker about how all of this just took me 20 minutes (incredible!) and looked so pro. I usually don't have time to mess around with attachments, but this one is so worth it.
