Dyson Supersonic hair dryer review: worth it?

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?

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.
