Dyson Supersonic Hairdryer Review: Worth the Investment 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. Then, 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, and it looked like never before! But of course, I convinced myself this was just because of the summer sun, so I held off.

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.

Let’s dive in and find out more about the technology, how to use it, and ultimately - if this hairdryer is for you:

How Does the Dyson Supersonic Work and What Makes It Special?

Let’s talk tech for a minute. Why did Dyson decide to create a hairdryer in the first place? Well, it all goes back to the company’s mission: to solve everyday problems using innovative technology. The founder, Sir James Dyson, famously created a vacuum that didn’t lose suction, and that same mindset went into their hair tech. Dyson realized that existing hairdryers were often too damaging—blasting hot air without much control and wanted to create a dryer that would actually protect hair, not just dry it.

The result? The intelligent heat control. The Dyson is constantly measuring the air temperature 40 times per second. This ensures that the heat never gets too high, protecting your hair from heat damage. Additionally, the motor is placed in the handle, which makes it lighter, easier to hold, and more efficient. It is powerful enough to dry your hair quicker without overheating, even if you have thick or long hair. Plus, the Dyson has multiple heat and airflow settings to fit your needs.

What Makes the Dyson Supersonic Different from Other Hairdryers?

So, what really sets the Dyson Supersonic apart from other hairdryers? For starters, the Intelligent heat control is a standout feature, and honestly, it’s not something you’ll find in any other hairdryer. Unlike traditional dryers that just pump out hot air, the Dyson constantly measures the temperature 40 times per second, adjusting to ensure it never gets too hot. This is a game-changer compared to other hairdryers that can easily overheat, leaving you with dry, damaged hair.

Then, there’s the motor in the handle, which makes the dryer lighter and easier to hold. With most blow-dryers, the motor sits in the head, making the dryer bulky and hard to handle for long periods. Dyson flipped that by putting the motor in the handle, making the dryer lighter, more balanced, and easier to hold. This design not only reduces strain on your arm but also makes the motor more powerful. So, whether you have thick or long hair, the Dyson dries it faster and more efficiently than most conventional dryers.

Then, there are the multiple heat and airflow settings, which give you more control than most blowdryers. Whether you're after smooth, straight hair or big, bouncy curls, you can choose the perfect setting. Lastly, the attachments, like the smoothing nozzle and diffuser, are designed for specific hair types and styling needs, something most other dryers just don’t offer.

First Impressions: Unboxing the Dyson Supersonic

When I finally clicked that purchase button, I couldn’t contain my excitement—this was happening! After some thought, I decided to splurge on the Dyson Supersonic™ Hair Dryer in 23.75 karat gold, a stunning option that features real gold leaf applied by hand using traditional gilding techniques. It was one of the colors on sale at the time, so while it sounds super fancy, the price was pretty similar to the original one. I was also excited to know that I’d be receiving a free presentation case with my order. When it finally arrived, I couldn’t wait to dive in and test it out.

I’ll be honest, though—it was a bit overwhelming at first. Seeing all those different attachments left me a little puzzled. I’m not someone who typically uses a lot of hair tools, so I wasn’t entirely sure which attachment to go for. But after watching a few Dyson videos online, I got the hang of it. Now, I mostly use two out of the five attachments, and sometimes I add a third one into the mix, but since I have thin, straight hair, the curly attachments aren’t really necessary for me. As for the presentation case—while it’s beautiful, it’s also quite big. Honestly, I don’t use it much; I just keep my Dyson in a cabinet in the bathroom, and it’s perfectly fine there.

Now for the part you’ve come here for:

How It Actually Performed on My Hair

I’ll be honest: I was a little skeptical when I first started seeing the Dyson Supersonic everywhere, especially with all the influencers hyping it up. I always think, "Do they really love it, or is there some ulterior motive?" But after testing it out during my vacation, I got a little taste of what it could do. The drying time was noticeably shorter, but I wasn’t totally sure if it was just the summer temperatures at play, so I didn’t want to get too excited. Would it live up to my expectations when I was back home in cooler weather?

Turns out, it totally did. Now that I have the Dyson at home, I can confidently say it delivers on its promise. Drying time has significantly decreased, even in the winter months. And as for the compliments—let me tell you, I’ve never gotten this many. My hair is pretty straight and thin, nothing special, but after using the regular styling concentrator followed by the flyaway attachment, I’ve been getting compliment after compliment. My hair looks smoother and shinier, almost like I’ve used a straightener, but without any of the damage.

I also noticed a big difference in how my hair feels. My scalp’s been a lot less itchy, and my hair feels denser, too. That said, I also switched to a Mason Pearson brush around the same time, so I think it's a combination of both the brush and the Dyson doing their magic. But I can say for sure that I definitely see and feel the difference!

My Final Verdict: Investment or Overrated Trend?

Overall, I'm really happy with my purchase of the Dyson Supersonic. As I mentioned earlier, I’m not someone who spends a lot of time on my hair, but when it comes to my scalp health, the density of my hair, and especially the drastic reduction in drying time, I think it’s worth the investment. Yes, it’s on the pricier side, but honestly, I dread blow-drying my hair, so cutting that time in half really makes a difference for me.

The one thing I am a little disappointed with is the cold air feature. I’m used to blow-drying with a cold setting to finish off my hair, especially close to my scalp, but with the Dyson, it’s more of a quick “shot of cold air” rather than a steady cold setting. The cold shot button doesn’t blow ice-cold air like some other hairdryers. Instead, it switches off the heat and keeps the airflow going, creating a burst of cool air (at room temperature) that helps set the style and reduce frizz. It’s not the cold I expected, but it does offer a gentle, cool finish to lock in the style. It’s not a deal-breaker, but I do miss that consistent cold blast I’m used to.

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

Taking care of your Dyson Supersonic is pretty simple and will help keep it in top shape. First, remember to clean the filter regularly. The filter helps the dryer run smoothly, and a clogged one can affect performance. Dyson recommends cleaning it about once a month or more if you use your dryer frequently. To do this, just remove the filter cover (it’s on the bottom) and brush off any dust or debris. Also, try not to pull on the cord too roughly—storing it neatly and avoiding tangles will keep it from getting damaged. Finally, give the motor a break every now and then! While the Dyson is powerful, it’s always a good idea to let it rest after a few rounds of drying to prevent overheating. With a little care, your Dyson Supersonic will continue to deliver flawless results for years to come.

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!
