I’ve been loyal to my wonderful professional model hair dryer for six years now. And while my Feather Jet is still going strong, I can’t keep my paws off the hair styling innovation from Dyson that’s changing the status quo of the humble hair dryer around the globe.

If you haven’t heard me complain enough about it before, my ultra-fine, baby like hair presents a lot of difficulties for me in the hair department. One of those being the process of heat styling. My fine hair strands are super thin in diameter, meaning it’s much less robust and more prone to damage. And because I have so little of it, every strand is absolutely precious to me. Consequently, I would only use heat stylers on very rare occasions or when I absolutely need to, and that includes my hair dryer.

Dyson Supersonic

Ever since the Dyson Supersonic hair dryer was released I read up on the making of the device and decided I needed to get my hands on it. Alas, it was a bit of a shock when I saw the price and didn’t think I’d ever be able to own one and I’m sure I’m not alone here. The price is a huge obstacle for so many consumers, and I’m sure the everyday person’s priority isn’t to spend upwards of $500 on a hair dryer when they could be buying groceries for the family, or putting money away for a holiday, or getting that whiny car a major service. Dyson really narrowed down their pool of potential buyers by pricing it so high. So how can a hair dryer possibly be so expensive? What makes this hair dryer so special that you should be convinced to spend $500 on one? Well, in my opinion nothing should make this hair dryer that expensive unless it blows out flakes of gold, so in other words the price is very, very exorbitant. Which is annoying because I seriously love this device but as I get older I’m starting to value the quality of products rather than quantity within a given timeframe. But personal opinions aside, I thought I’d use this post to help others understand why this hair dryer is so different to the others on the market, and if in the end it does convince you to go out and splurge on a Dyson Supersonic, than I hope you enjoy your new purchase as much as I did.


The Dyson Supersonic comes housed within a large white box. Upon opening, you are greeted with a note that reads,

Hello. And welcome to your new hair dyer.

The kit comes with three attachments, all with a magnetic snap lock which makes it gloriously easy to customise your device depending on the desired effect. There is a smoothing nozzle, a styling concentrator (both a with thin nose), and a diffuser to stimulate natural drying and keep the natural body of your hair intact. It also comes with a non-slip mat, and a storage hanger cord should you wish to hang it up anywhere (or you can purchase the presentation stand for $99 – yay extra money). You might even be lucky enough to nab yourself one of the sets with a bonus storage case.

The thing that makes this hair dryer most impressive is the time, research and development that went into the execution of this device. Apparently, Dyson has spent $71 million developing the Supersonic. And all research, development and testing was completed in fit-for-purpose built laboratories with their own team of engineers in England, starting off with learning the science of hair. For the efficacy of the product for both personal and professional use, Dyson also employed trichologists, scientists and some of the top hair stylists in the world, including those who have worked on big-name celebrities. According to Dyson, 1600 kilometres of real human hair of various types was used for the testing of the prototypes. And it wasn’t just a few prototypes, try 600 different versions! As a researcher myself, the depth to which they researched, designed, and tested is something I both marvelled in and was shocked by.

The Dyson Supersonic is powered by a V9 digital motor that spins up to 110,000rpm, with 13 impeller blades, and a total diameter of 27mm. A rubber mount helps to reduce the transfer of noise by preventing the motor from vibrating against the inside of the handle. Now, they say it spins at an almost inaudible frequency, but I don’t think that’s entirely true. You can still hear the dryer working. I wouldn’t say it’s as loud as my Feather Jet, but you can definitely still hear the motor in this dryer. The thing I love most about this dryer is the fact that the motor so bloody light (700g), and is unconventionally positioned in the handle which shifts the weight distribution to the handle. For me, this means a more comfortable styling process which doesn’t tire my arms, and it allows for better control in my opinion. The placement of the motor is thanks to the small size which contrasts against the conventional hair dryers on the market with bulky motors necessitating placement in the head of the dryer. Of course, these do have a notorious risk of sucking in hair and trapping it in the dryer, especially for long-haired individuals, and I’m sure I’m not the only one who has suffered through this a few times. But the design of the Dyson pretty much eliminates this risk.

Dyson has also adopted their ‘air-multiplier’ technology to this hair dryer, which essentially means it sucks in air three times as much in order to produce high-velocity air, travelling up to roughly 170km/hr. The Dyson Supersonic is the only hair dryer to date that has this technology.

Dyson also has a similar technology to some modern hair styling products which aim to prevent extreme heat damage. The Supersonic has a glass bead thermal sensor that measures the exit flow air temperature 20 times per second, before transmitting this data to the microprocessor which can intelligently adjust and control the heating element to protect your natural shine and maintain a drying temp that won’t cause excessive heat damage. It also features ionic technology, but that’s never really something I’ve gotten too excited about in the past.

Speaking of air temperature, five years of research has shown Dyson that the optimal temperature for both drying hair and preventing heat damage sits below 150°C. Dyson give the user the option to choose their own temperature with four different heat settings: 100°C for fast drying and styling, 80°C for regular drying, 60°C for gentle drying, and a cool shot temp of 28°C which can help set hair. Along with this, three different air velocity options are also available to the user for fast drying, regular drying or gentle styling. Both are indicated with stylish LED lights.

Ultimately, I really love my Dyson Supersonic dryer, I really bloody do. I love the futuristic and unique design, I love how small and light it is, making it more practical for storage and travelling than your conventional dryer. It’s more comfortable to use with better control thanks to the manufacture and placement of the motor. Although not silent, it is definitely more quiet than my professional dryer. The lower temperatures dry my fine hair just perfectly without making it feel as dehydrated as my previous model (this might be different for those with thicker hair). And, the magnetic snap lock attachment are a breeze to use and change for your desired outcome. Finally, the effort that’s put into this device is unsurpassed by competitors. But, this sort of focus on state-of-the-art design and engineering didn’t come cheap to Dyson, and consequently doesn’t come cheap for the consumer either.  Do I think it’s worth splurging $500 odd dollars on it? Honestly, when it comes down to looking at it from a realistic and practical point of view for the general public, I do not condone the monetary value of the device. I think it is overpriced for the outcome, albeit an improvement on my previous dryer. In the end, I’m torn. I really do love using it and don’t want to go back to using a conventional dryer, but if I faced getting a replacement in the future I wouldn’t choose to repurchase the Supersonic purely based on its price which isn’t feasible for many people.

Have you used the Dyson Supersonic for yourself? What were your honest thoughts on it? Or, if you’re someone who knows about it, have you considered splurging on it? Really, all I hoped for with this post was to inform you on what is actually so different about it aside from the visual appearance, not to persuade you to buy or not to buy.

  1. I really enjoy my Dyson hair dryer! It works really well for my thick hair, however I am still not sold on the price point. I think my GHD hair dryer (which is about half the price) works just as well. It’s an interesting concept…

    1. Yep neither am I, as I said in my post as well. The reason I love it more than the usual dryer is the size and weight of it. It’s much easier and comfortable to use over the standard dryer. Just don’t think that’s worth spending the big dollars though. Something has to cover the $71 million put into the creation of this device though LOL. Interestingly, the price has dropped by about $100 since it first came out. It was originally $599 if I remember correctly, although I could be wrong!

  2. This review is amazing! I don’t own nor have tried the Dyson hairdryer, but my thoughts on it align with you. Ultimately that price is ridiculous! At the moment I’m using a Parlux and love it. I’m sure I’d love the Dyson more if I tried it, but the Parlux is still pretty good.

    1. The Parlux name is pretty big in the hair dryer world, but I haven’t tried one myself. And they are obviously more affordable than the Dyson, which would make it a good brand to try if you can’t go that step further and splurge a huge amount of cash on a Dyson.

  3. This hair dryer does sound amazing and I will need to buy a new hair dryer in the not so distant future but I can’t really justify this price just for a hair dryer!

    1. I agree, nor can a lot of people. I get that the effort and money that went into this device constitutes a heavier price tag, but that amount just prices so many people out of their consumer base!

    1. Haha I know what you mean. If you’re not someone who uses a hair dryer frequently (like me for example – I use it after every wash), then it’s really not that practical to spend this amount of money on one.

  4. I need this now! I’m actually in need of a new hair dryer so this one would be perfect for me.

    1. Thanks so much Rochelle, comments like that warm my heart! I think that whenever people see or hear of the Dyson dryer that all they think about is how expensive it is, so I wanted to try and communicate the reasons WHY it is the price it is and I’m glad you feel I did that justice!

  5. Thanks for the in-depth look Fel! I’m so torn on this. Part of me thinks it would be worth it for me as I use a hairdryer every single day and my hair is fine and damaged (especially since I went blonde). More than that though, I wonder if the better ergonomic design would be easier on my hands on RA flare days. Buuuuuuut I just can’t do it. I just cannot cough up that much haha. Maybe when I’m a millionaire.

    1. Oooohhh yes I actually did think of you while writing the post! Feel free to borrow it and see if it is something you may want to save up for. But yeah, as with the others I do agree that the price just makes it too hard for people to own one, unless they have a big disposable income!
