REVIEW Dyson Supersonic™ Hair Dryer UPDATE

Dyson Supersonic™ Hair Dryer

A fool and her money… Do I use that opening a lot? This review is based on my personal experience and honestly, I feel relieved it’s all over and I promise never to be so silly again.


The hairdryer designed to dry your hair fast, but with minimal damage, launched a couple of years ago. I dismissed it immediately because of the £300 price tag. But the convincer was someone with Instagram perfect hair who personally recommended it to me. Of course, I found out later she wears very expensive, custom-made, real hair extensions.

It took a lot of planning to buy this hairdryer, even I know that no hairdryer is worth £300. You’re paying for the Dyson brand name, the research, the huge marketing campaign and the innovative technology, we get it!

But I really did need to justify (to myself at least), such a big spend. I put an odd £20.00 away now and then and £150.00 soon built up. The other £150.00 was my Valentine’s present. I told a little white lie and implied that the dryer was reduced to £150.00 as a ‘one day only’ Valentine promotion. I then spent the rest of the day fretting that Mark would tell his friends and they’d say, here’s £300, get me two!

I thought the cost would pay for itself if, in the long-term, it helped protect my fine, highlighted hair from heat damage. As I always say, older hair is knackered hair, it’s been through 40 plus years of dyeing, heat styling and product overload, it deserves the best of care.


The dryer is beautifully packaged, it’s a good-looking piece of kit. There’s a little rubber mat to lay the dryer on to protect it, a useless hanging thingy and 3 magnetic attachments, although I only used the smaller, smoothing attachment. The fact that it just snaps on and you can easily rotate the nozzle in any direction is really useful.

I didn’t think it was particularly light, but the compact size means it’s really comfortable to hold and easy to use. The controls are simple and you can switch heat and power settings with a flick of the thumb. It is thoughtfully designed and really does reduce hair drying time which of course is what we all want.


It made my hair flat and fly away. I tried every combination of speed/power/hair styling products – same thing. I thought it’s definitely me not the dryer BECAUSE IT COST £300! So, I looked up the official hair drying videos.

I read somewhere that if you’re unhappy about the dryer and want to return it, Dyson sends someone out to teach you how to blow dry your hair. That’s crazy, but I think what actually happens is they invite you to a salon to demonstrate the correct drying technique.

I’ve watched a few of these official videos and the result is always the same – hair is lovely and smooth, but it lacks body.


I have to admit, the condition of my hair DID improve over the 5 weeks I used the dryer (2 x a week) and my hair would always look smooth and shiny the NEXT day. I know this was my goal, but I wanted my hair to look good the DAY I washed it.

My hair never looked right, not one single time, it was always was too floppy and slippy, I felt it just wasn’t worth the £300 price tag. I’ve had fairly expensive hair dryers in the past, but they were usually too heavy so I always went back to the BaByliss Nano Travel Dryer (£15.00). It’s light – half the weight of the Dyson, less powerful at 1200W and has only 2 heat and 2-speed settings, but it gets the job done. I felt like me again.

I knew I messed up and decided to return the Dyson.


I bought the Dyson online from John Lewis and thought, this should be straightforward enough to return. It doesn’t work as expected, so not fit for purpose (for my hair).

Instead of the Returns Desk (hassle-free, helpful and polite), I had to go to the Electrical Department – warning flag duly raised, I’ve returned products there before, I knew I’d have to plead my case.

To cut a long rambling story short, I had a bit of verbal tussle with the very rude sales assistant.

I hadn’t realised I was four days past the 35 days cut off point for a refund and that they’re not legally obliged to give me my money back just because I didn’t like the product – her words.

My argument was that the dryer wasn’t working for me, so surely I’m entitled to a refund from John Lewis or Dyson. I mean, what about all that customer satisfaction/the customer always right jazz?

I said I’d go straight to Dyson and she said they wouldn’t refund my money either. I was panicky (£300!) and admittedly, a tad rude back.  She then disappeared and came back with, “I’ve spoken to my manager and in this case, we’ll make an exception and offer you a full refund.” Oh, how those words must’ve hurt her.

Obviously, she couldn’t leave my small victory there, when the refund was finally completed, she spat, “Of course, John Lewis will now have to sell the dryer at a reduced price.”

I replied, “Well, someone will get a bargain because it’s hardly been used.”

So, if you’re in the market for a perfect Dyson hair dryer for less than retail price, get thee to John Lewis in Brent Cross – just don’t tell rude Sarah I sent you!

Dyson Supersonic™ Hair Dryer Original (if you can still get it) £299.99

Boots * £329.00 but with 5 attachments STILL out of stock though!

UPDATE 20/01/22

I admit it, I was too hasty returning the Supersonic. I bought the Dyson Volume + Shape Airwrap Review here

    In reading this I am VERY disappointed in the attitude from the rep… To be honest, they don’t have to sell it at as reduced price, they could sent it back to dyson as faulty, they could put it back on the shelf ( depending on condition), they could send it back to distribution. There are a hundred options, it’s really not your problem as a customer. I’m disappointed it didn’t work for you as well as I had my eye on this one!

    Shame on that rep seriously, if I heard one of my people treat a customer like that there would be a very unpleasant conversation coming their way. It doesn’t affect their paycheque so what does she care.

      Hi There, I think she was just trying to make me feel bad because I received a full refund.

      John Lewis have a good reputation for customer service, but I’ve always had to fight my corner when it comes to returning faulty electrical equipment. I returned two pair of ‘Happy’ ear phones – got a grilling and then my mac went in for repair and they dared to say the screen was scratched – obviously to cover themselves if they damaged it. We made them examine it in bright light and they admitted defeat.

      My hackles were up when I realised she had a bad attitude and I suppose, legally, they didn’t have to give a refund, but as you say, they shouldn’t have treated me like that.

      Thanks for commenting, much appreciated.

    Ah thank you for reviewing this
    .. I literally was a month (till birthday) away from buying it because it has been on my wishlist. I have only heard good things about it, mainly how light and quiet it is. My GHD dryer somehow stopped working, also bought from JL and they didn’t refund!

      Hi There,

      Thanks for commenting.

      If I’d seen the results of the ‘official’ Dyson tutorials, I wouldn’t have touched it. You can see yourself that hair is flat and flyaway after using the dryer.

      I would happily fork out £150 for it, because my hair was absolutely perfect the SECOND day, but £300 is pushing it.

      What you could do – if your embarrassment factor is zero, is go and try it out in John Lewis with damp hair.

      I know a lot of blogger and vloggers were sent the Dyson when it launched a couple of years ago – I bet they couldn’t believe their luck, but I’ve yet to find one who didn’t like it…

      I forgot to mention in the blog that ‘Rude Sarah’ said my Dyson was the only one ever to be returned!

    Great review Ann-Marie. My hairdresser uses the Dyson on me when i get my hair done and i had noticed my hair also became whispey and lacking in volume.
    I also use the light weight Babylis hairdryer for travelling and i love it.
    I had been tempted to buy the Dyson until i saw that my hair was lacking in volume. I can’t use GHD straighteners for the same reason. Again my Babylis straighteners are fantastic.
    I have been recommended the GHD hairdryer though and at £100 it seems like a better investment. I handled it in JL the other day and they are only slightly heavier than the Dyson and the Wella one i currently use.
    Thankfully, you got a full refund. It is an incredible amount to invest for just a hairdryer after all.

    P.S i got an anti-static Professional hairdryer online for a knock down £54 over 3 years ago. Used 4-5 times a week and its only starting to get hot now. Brilliant!
