Why everyone is obsessed with the Dyson Supersonic Hairdryer

I’ll be honest, my mum has one and I will take the opportunity to steal it for 10 minutes to dry my hair. I’d love to know the science behind how it can dry my thick head of hair in half the time that my Tresemme one can.

I’m sure you have all seen it on your TikTok feed, spotted it behind the scenes at various fashion weeks, or clocked it on your favourite influencers bathroom shelves. This hair tool is everywhere, and for good reason. 

The science behind the wonder

Have you ever wondered what makes it so special? And more importantly, is it worth the big price tag? Science may help us here, I actually looked it up. It blew my mind a bit at first so let’s skip to the key points. 

The Dyson Supersonic Hairdryer can dry your hair up to 50 times faster than others thanks to a motor that spins insanely fast, pushing out a super focused stream of air. Plus, it’s got smart heat control that checks the temperature 20 times every second, making sure it’s never too hot to damage your hair. The airflow tech spreads the air evenly and gently, which helps stop frizz and keep your hair healthy. Oh, and the motor’s actually in the handle, not the head, so the weight is balanced better, making it way easier to hold and use.

Sounds fancy, right? Even if I don’t fully get the tech, I’m definitely a fan of the results

It turns out the fashion world is just as obsessed. After sponsoring the likes of New York Fashion Week, the Dyson Supersonic Hairdryer has basically earned its place as the unofficial backstage MVP. Top stylists swear by it, celebs love it, and I’m starting to think it might be the real reason models manage to look that flawless after 6 outfit changes and zero sleep.

I’ve always been a bit fascinated by how it all works behind the scenes. How does everyone still have perfect hair after being yanked in and out of looks all day? Now it’s starting to click. Maybe the Dyson is the secret sauce. Honestly, I might need to get one just to see if it turns me into runway material (or at least saves me some arm ache).

So, whether you’re a full-on haircare pro or just someone who wants to dry their hair without it turning into a frizz bomb, the Dyson kind of speaks for itself. It’s smart, it’s speedy, and it actually makes styling feel like less of a chore. If you’ve ever stared at your old hairdryer mid-use and thought, “Surely there has to be something better,” - there is. And honestly? This might be it.

And if you’re the one who ends up winning ours… just know I’ll be a little jealous.
