Dyson Supersonic hair dryer review: worth it?

June 13, 2016

Dyson Supersonic hair dryer

There is one thing that sticks out in everyone’s mind when the Dyson Supersonic hair dryer is discussed: the price. So, let’s get this out of the way: the Dyson Supersonic hair dryer* is €399. That’s about €360 more expensive than the average hair dryer. It’s four weeks’ worth of groceries for a family of four. That’s 40 packets of cigarettes (which, actually, makes it seem really reasonable – as an ex-smoker, I think I’ll always think in terms of cigarette prices). That’s a pair of Manolo Blahnik shoes. It’s 133 cups of coffee or 40 of Jo Burger’s lunch specials (a burger plus fries or homemade lemonade).

But value, like so many other things, is so very subjective. To one person, the comparison that sticks out there will be the groceries. For another, it’ll be the Manolo Blahniks. How can we say if something is worth €400 when, to one person, €400 will be a pair of designer shoes – and to another, it’ll be the means by which they feed their family for a month?

So let’s say this: we each decide what to spend our money on, and no one person’s decision is more or less valid than another’s. If €400 is an insane figure to you, that makes total sense: don’t buy it. If, however, you think you could be enticed to spend €400 on a hair dryer designed by magicians in the hair dryer engineering equivalent of NASA, then, keep reading.

The Dyson Supersonic hair dryer is very, very good. And honestly, I was fully prepared to be sceptical, despite the fact that I was given the device as a press sample*. (In fact, that probably makes me more likely to diss it; if I’d bought it myself, I’d be so determined to convince myself – and everyone else – that it was worth what I’d spent. Having been given it, I’d feel freer to say if I thought it was a false economy.)

Granted, I don’t use my hair dryer for anything fancy; I diffuse my curly mop every second day, which is the hair drying equivalent of letting it dry naturally, but adds a little more volume. So how much of a difference could it really make to my life?

Dyson Supersonic hair dryer

Here’s me – no make-up, hair dried with the Dyson, having been rained on – STILL NOT FRIZZY!

Dyson, for years, has been the last word in vacuum cleaners (don’t use the dreaded H-word; that’s a brand name, and a Dyson is a Dyson) – so, for it to make this huge leap into drying hair seems nuts, right? But it’s all hot air – if you’ll excuse the pun – and Dyson prides itself on developing super-fast motors for incredibly efficient air-whirring. (That’s the scientific term.) There are a whole load of jargony facts I could spout about the Dyson Supersonic hair dryer (if I remembered them), but let’s talk about what people really care about.

For starters, the Dyson Supersonic hair dryer is really light – which, actually, takes some getting used to, when you’ve been accustomed to building up muscle strength in your hand just do blow-dry your hair. It’s about half the weight of my old dryer (a Babyliss number that’s been my faithful friend for about three years, even if, of late, it’s been burning my head a little too often for my liking), and designed ergonomically to be more comfortable in your hand. Is that true? Maybe. My arm doesn’t cramp, drying my hair with my Dyson, but I’m not totally convinced that’s because of expert design – it helps that I can dry my hair in about half the time.

Which brings me neatly on to the biggest draw, in my mind, of the Dyson: its time-saving capabilities. I remember, once, working out how much my time was worth – in an effort to figure out whether it was worth eBaying my clothes, rather than consigning them with Siopaella – and it’s something I would urge every self-employed person to do. If you know how much you can earn in an hour, it makes it very easy to say no to that lunch date you don’t really want to go on.

So, if the Dyson Supersonic hair dryer takes 10 minutes to dry my hair – where my old dryer took at least 30 minutes – that’s 20 minutes I’m saving, every second day. That’s around an hour and a half a week, more if you have longer hair or wash it every day.

It’s not just time-saving that interests me, though; for anyone with curly hair, trying to dry it without infusing it with frizz is a seriously challenging endeavour. (Check out my blog post on how I blow-dry my hair for my top tips and products.) I haven’t changed a single thing since I started using my Dyson Supersonic hair dryer – I’m using the same products, with the same method – and the frizz has all but disappeared. That sounds too good to be true, and I was as disbelieving as anyone else; it took me five goes before I really believed what I was seeing. Straight-haired people won’t understand this, but when you’ve curly hair, you start to think that frizz is just an inevitability. The day is won by the amount of frizz you manage to tame – but you know you’ll never get it all.

Well, I don’t know what kind of wizardry Dyson cooked up in this hair dryer, but somehow my tresses are bone dry and frizz-free in minutes. I can’t speak for the straightening nozzle because I haven’t used it; straight hair makes me look like my dad’s late auntie Eileen.

Another big buzz around the Dyson Supersonic hair dryer is the fact that it’s engineered to have very reliable heat control, which means it will deliver just the right amount of heat to dry and smooth hair without damaging it. Can I confirm this? Clearly not; I’ve only had it for a few weeks, so I’d need a few months of use to tell you whether my hair was more or less damaged with my last dryer. (My hunch is that they’re telling the truth; I haven’t burnt my head once since using my Dyson, and that used to be a daily occurrence.)

So, would I buy it? To be perfectly honest, not right now. I’m planning a holiday to the US to visit my sister in August, and I’m currently chasing about 20 invoices that are overdue so, very practically speaking, I couldn’t afford it. But I would definitely be saving up to buy one; I love spending money, especially if I can say things like, “well, I use this four times a week and it saves me over an hour, so that’s more than three days saved in a year…” (You can justify anything if you try hard enough.)

Will it change your life? Probably not – I’m not an insane Dyson evangelist. But if you have curly hair, spend ages drying it and struggle with frizz, it might just save your sanity.

    Hi Rosemary
    I was waiting for your review as I myself had the chance to try out the Dyson hairdryer. Dylan Bradshaw was offering free blow dries with the Dyson so I signed up as I was really interested in purchasing one if it was worth all the hype.

    My number one reason for thinking I might invest was the so called lightness of the Dyson. First things first, it didn’t feel much lighter to me than a regular hairdryer. I was expecting it to be noticably lighter. You have mentioned in your review that it’s so much lighter than your babyliss but did you actually look up the weights. The Dyson is 600g. A normal salon hairdryer averages 500g – lighter than the Dyson. I couldn’t believe it.

    The other main thing that piqued my interest was the fact that it was going to dry my hair in half the time of a normal hairdryer. Again not so. It took the stylist just the same length of time to dry my hair as it would have with their regular hairdryer.

    I really was disappointed as I was willing to spend my hard earned cash on something that to me would have made my life a lot easier –
    I have a lot of hair!

    I’m also just a little disappointed that you’ve gave it such a glowing review. It has been marketed as a super light product but it’s just false. Did you actually try lift your hairdryer and then pick up Dyson and can you honestly say it’s unbelievably lighter?

    Anyway just said I’d give you my opinion!

      Hi Jennifer!

      Okay, so firstly no, I didn’t double check the weight – my own dryer was not a salon dryer (just a cheap one from Boots) and I did a very unscientific, hold one in one hand and one in the other, both with diffuser attachments on… I’ve also binned the dryer (read: given it to my mother, I’m so generous) so can’t weigh it properly now which is really annoying because I’d be intrigued to see if I was just imagining it!

      On the drying front, it 100% dries my hair quicker than my last dryer. Like, there’s no question. Now, that being said, when I went to Dylan Bradshaw and had my hair dried there, they took the same amount of time as they would have with a regular dryer; I think hair stylists have a certain method and way of doing things, and so they’re not so much focusing on how long it takes to “dry” the hair, as doing a particular style, if that makes sense?

      I’m sorry if you feel I’ve misled you in any way; as always, it’s just my opinion (although honestly the drying time IS halved!) – and I’ve never denied the fact that I ALWAYS buy into a gimmick, so there may be a bit of that at play too!

    Hi rosemary,
    Interesting stuff about the dyson,……. Have semi wavy/ frizzy hair which has been blow dried nearly EVERY DAY ,for the last 40 yrs , so would be very tempted to give it a go , so Tks for the info……. This has nothing to do with the dyson , but do you really look like SHERIDAN SMITH OR WHAT ????is it my imagination??????

      I don’t think anyone’s ever said that before Francesca! I just Google Image searched her there, and I can see a vague resemblance – but only when she has no makeup on! Scarlet for me! Ha!

    I have just used my friends dyson hair dryer now I am a hairstylist & it’s certainly a lot lighter than our hair dryers in work . It’s definitely a lot quicker & certainly a lot smoother , I am so impressed with it can’t wait to purchase one .

    My daughter gets a lions mane around the front of her hair by the time it is dry! We can use products and it helps for a bit but by noon here comes the lions mane. Just a big puff of hair around her face. I am hoping this hair dryer might help with that!

  • Reply Karen July 24, 2016 at 1:47 pm


    I purchased my last week. I like it, I don’t love it. Takes the same amount of time to dry my hair and does make it very soft and smooth. In fact so soft and smooth I can’t do anything with it . I’m taking it back !

    So nice to see a review on this fancy gadget by another ‘curly girl’. The Dyson dryer was recently released in the USA and I snapped one up when I saw it on I live in a dry temperate climate (Northern California), so I mostly just air dry my hair. Every so often though, I want more formed curls. I find it really requires a dryer and diffuser to get that effect. This is a long process spent with my head hanging upside down, that leaves me flushed and perspiring. Anything to speed it up is worth the money, in my opinion. I’ve only used the Dyson a couple times so far. I am underwhelmed. After you snap on the diffuser (which is the only way I use a hair dryer), there is not an immediately noticeable difference from a regular dryer used with a diffuser. I was comparing it to the Xtava Black Orchid diffuser on a Deva Ion hair dryer. Frankly, for the astronomically high price, I expected more of WOW factor. I was debating whether to take it back for a refund, but after reading your comments I may try again a few times with more heat and see if there is any noticeable difference.

    I just moved to Singapore from the US. Getting a hair dryer was on my list of things to do. The Dyson has not been released in the US yet. However I have to confess I am drawn to the brand. I love their vacuum cleaners and fans. Dyson as a brand is kind of like Apple. There is something about the industrial design that draws you to it. Functionally I have found their products to be superior. It is the Mac vs PC question really isn’t it?

    For me, it is about form follows function. I am willing to pay more for a product that satisfies both. Dyson products are superbly designed and it makes me happy using them.

    Your are so overwhelmingly immerse in insane shopping capitalism that you do not realize how absolutely insane is to claim the goodness of a product that is 20 times more expensive than any other good brand of hairdryers…

    It is insanely inmoral to even talk about these shopping madness they way the world is right now.

    You people have too much money. It is a shame for the human race…

  • Reply Ian Meredith December 31, 2016 at 2:14 pm

    “Insanely immoral”? “You people”? Must be nice to be you sitting in judgement of others, although you failed to mention exactly what you are doing to improve the world! The people reading this review are gathering information about a product to determine whether it is a worthwhile investment. That’s about as responsible as you can get! Some of them, like myself, are professional stylists that use a hair dryer as a tool….much like a carpenter uses a nail gun, although a hammer gets the job done for at less than 20 times the price. But even if you are just an individual who dries only their own hair, it shouldn’t be anyone else’s business to pass judgement on how someone chooses to spend their hard-earned money! Yes, there are cheaper options and if you are satisfied with their performance, you should by all means use that…especially since you somehow correlate your choice with saving the world from all the insane, immoral Dyson users! No one is going to force one on you.

    I love your simplicity of having no make up and I also like those lovely curls without the frizz. Apart from shampoo, what is the best hair treatment to maintain those lovely curls.

    If your going to review anything then you really should test it thouraly ie on straight hair as well, lots of words but not actually much useful info to help anyone to know if the dyson dryer it worth the money, I think it’s great getting free items to review and genuinely good for you but come on my lovely haven’t you hear the phrase ‘if a jobs worth doing it’s worth doing well’, you’ve been bit of a slacker on this review. Well done for getting a free dyson dryer though . Xx

      Hi Nic,

      Any reviews I do – of any product – are going to be reviewed by me, on me. I have curly hair. There’s nothing I can do about that! There are loads of reviews out there on the Dyson Supersonic at this stage, by women with differing hair textures, so I’m sure people can find a wide range of reviews to give a fuller picture. 😀 Thanks for reading!
