Dyson Supersonic Hair Dryer Review: Worth It or an Overrated Trend?

“Invest in your hair, it’s the crown you never take off”

When it comes to my hair, let’s just say I’m a bit lazy. I’ve always kept it simple… blow dry and go. So, when the Dyson Supersonic Hairdryer kept popping up all over social media, with every influencer and their mother swearing by it, I couldn’t help but wonder: Do I really need to drop that much money on a hair tool?

I mean, influencing myself out of needing the Dyson Airwrap was easy. If I thought about it a bit, I’d probably use it for a couple of days and then get over it. However, the thought of owning a Supersonic Hairdryer kept lingering…

The only Dyson product I was familiar with before TikTok took over was the vacuum cleaner, which I absolutely love, but that’s a story for another time. Over the summer, I stayed at a few hotels, most of which had a Dyson blow dryer in the room. I was so excited to try it. My hair dried in seconds. But this could also be because of the summer sun… right?

Then my hairdresser pointed out that my hair’s pretty dry (thanks, my 10-year-old trusted blow-dryer) and suggested I might be damaging it with heat styling. That’s when I started thinking maybe this fancy hair tool was worth a try. So, I finally decided to take the plunge.

Now, after using it for a couple of months, I’ve reached a verdict. Was the investment really worth it, or is the Dyson Supersonic Hairdryer just another overpriced gadget?

Well, here’s what I’ve found out…

Quick verdict: Is the Dyson Supersonic Hair Dryer Worth the Investment?

Short answer: yes, but it depends on how often you use it and what you expect from a hair dryer.

I’ve been using the Dyson Supersonic for a couple of years now, and it’s one of the few beauty tools that genuinely made a difference in my routine. It dries hair noticeably faster and is easy to use. Over time, I also noticed less frizz and smoother results overall.

That said, it’s still a big investment. If you only use a hair dryer occasionally, you might not get the full value out of it. But if you use it regularly, the difference is noticeable.

What it does well:

• Dries hair noticeably faster

• Comfortable to hold

• Helps reduce frizz and leaves hair smoother over time

What to keep in mind:

• Expensive

• It’s not a magic one-time tool.. you need to use it consistently to really notice the difference

• It’s not really lightweight

For a closer look, let’s get into the details:

How Does the Dyson Supersonic Work and What Makes It Different from other Hair Dryers?

If you've ever wondered why the Dyson Supersonic costs so much more than a regular hairdryer, a lot of it comes down to the technology inside. And while I'm not usually someone who gets particularly excited about the technical specifications of a hairdryer, there are a few things worth knowing.

First, there's the intelligent heat control. The Dyson measures the air temperature 40 times per second and adjusts the heat to prevent it from getting too hot. If you've ever used a hairdryer that feels like it's practically burning your scalp, you'll understand why this is useful. The idea is to dry your hair quickly without exposing it to excessive heat, which can cause damage over time.

Another interesting detail is the motor, which Dyson placed inside the handle rather than the head of the dryer. This changes how the weight is distributed, making it feel more balanced in your hand. It's a relatively small design detail, but one that can make a difference when you're standing in front of the mirror drying your hair, especially if you have long or thick hair.

The Supersonic also has several heat and airflow settings, so you can adjust both depending on how you like to dry or style your hair. And then there are the attachments, including the smoothing nozzle and diffuser, which are designed for different hair types and styling needs.

Of course, none of this automatically means it's worth the price. What matters is whether these features actually make a difference when you're using it, which is what we’re about to find out..

First Impressions: Unboxing the Dyson Supersonic

After going back and forth for a while, I finally decided to treat myself to the Dyson Supersonic Hair Dryer. I ended up getting the 23.75-karat gold version, which features real gold leaf applied by hand using traditional gilding techniques. Now, that sounds rather extravagant, but it actually happened to be on sale at the time, so I paid roughly the same as I would have for the regular model. It even came with a complimentary presentation case, which was another nice bonus.

I was genuinely excited when it arrived, although I'll admit that all those different attachments were a little overwhelming at first. I'm not someone who typically uses a lot of hair styling tools, so I wasn't entirely sure where to start. After watching a few Dyson videos, though, I quickly figured out which attachments worked best for my hair.

These days, I mostly use two of the five attachments, occasionally three. Since my hair is fine and straight, I don't really have much use for the ones designed for curly hair, but I can see how they'd be useful for someone with a different hair type.

As for the presentation case, it does look really nice, and I know plenty of people use theirs to store their Dyson. The only problem is that it's quite tall and doesn't fit inside my bathroom cabinets. So I ended up putting it on the top shelf of a closet, and I don't think I've looked at it since. Meanwhile, the hair dryer itself just lives in my bathroom cabinet. I can appreciate the case, but it's not something I personally get much use out of.

Now for the part you’ve come here for:

How It Actually Performed on My Hair

I'll be honest, I was pretty skeptical when I first started seeing the Dyson Supersonic everywhere, especially with so many influencers recommending it. I always find myself wondering whether they genuinely love something or whether there's another reason they're talking about it.

But here's the thing: I absolutely hate blow-drying my hair. It's probably my least favorite part of washing it, and I've genuinely postponed washing my hair simply because I couldn't be bothered with the drying afterward. So when I heard that the Dyson was supposed to dry hair significantly faster, that was the one thing that really caught my attention.

During a road trip across Europe, I happened to stay at several hotels that had Dyson hair dryers in their bathrooms, which gave me the perfect opportunity to try one without actually buying it. And I have to admit, I was impressed. My hair seemed to dry noticeably faster than usual, although I wasn't entirely convinced. We were traveling in the middle of summer, and I couldn't help wondering whether the warm weather was doing half the work.

Still, those hotel experiences were ultimately what convinced me to buy one. And having now used the Dyson at home, including throughout the colder winter months, I can confidently say that it really does dry my hair faster. For someone who dislikes blow-drying as much as I do, that alone makes a huge difference.

What I hadn't expected, though, was how much better my hair would look afterward. My hair is naturally fine and straight, but when I use the regular styling concentrator followed by the flyaway attachment, it looks noticeably smoother and shinier, almost as though I've used a straightener. I've even received quite a few compliments on it, which certainly wasn't something I expected from changing my hair dryer.

I've also noticed that my scalp feels less itchy and my hair seems a little fuller. Although, to be fair, I started using a Mason Pearson hairbrush around the same time, so I can't say for certain how much of that is down to the Dyson. Either way, I'm really happy with how my hair looks and feels now.

My Final Verdict: Investment or Overrated Trend?

So, is the Dyson Supersonic Hair Dryer actually worth the money? For me, absolutely. I've had mine for almost three years now, and I'm still just as happy with it as when I first bought it. It dries my hair in roughly half the time, leaves it looking smoother and shinier, and has become a regular part of my hair care routine.

I did have one complaint for quite a while, though. I thought the Dyson didn't have a proper cold setting. I've always liked finishing with cold air, especially around my scalp, but I thought the only way to do that was by holding down the cold shot button. Not exactly convenient.

Well, it turns out I was wrong. I eventually discovered that if you keep lowering the temperature, you can actually turn the heat off completely and use the Dyson with a continuous cool airflow. So the setting I'd been missing was there all along. I just hadn't figured out how to use it.

With that little mystery solved, I really don't have much to complain about. Of course, it's still a lot of money to spend on a hair dryer, and I wouldn't suggest that everyone needs one. But after all this time, I can say that I don't regret spending the money on mine. And if you can find it on sale, even better.

Made the Purchase? Here’s How to Take Care of Your Dyson Supersonic Hairdryer

Considering how much the Dyson Supersonic costs, you'll probably want to keep it in good condition for as long as possible. Luckily, there's not much maintenance involved.

The most important thing is to keep the filter clean. Dyson recommends checking and cleaning it approximately once a month, but I actually check mine every time I use it. It's become a bit of a habit, and it only takes a few seconds.

The filter is located at the bottom of the handle, and you can simply twist and slide the cover down to check whether there's any dust buildup. If there is, I use a soft, dry toothbrush to gently brush it away. Just make sure the hair dryer is unplugged before cleaning it.

I'd also recommend being careful with the cord. Avoid wrapping it too tightly around the hair dryer or pulling on it when unplugging it. I usually just keep mine in my bathroom cabinet, so there's no complicated storage routine involved.

Overall, it’s a worthwhile investment for anyone looking to elevate their hair care routine, and I’m excited to see how it continues to work its magic on my hair. If you have any questions or need more info about the Dyson Supersonic, feel free to reach out — I’m always happy to help!
