Dyson Supersonic Hair Dryer Review – Intelligent Heat Control Haircare?

Dyson Supersonic Haircare Styler Review

Dyson – the premium-quality vacuum and fan manufacturer – just released its first hair dryer called the Dyson Supersonic. Is it worth the $400+ price tag? Let’s take a closer look in our Dyson Supersonic review.

What is the Dyson Supersonic?

Dyson just unveiled the Dyson Supersonic, its first ever hair dryer. The dryer is pricey, lightweight, and promises to be the best hair dryer ever made.

Using advanced technologies, the Dyson Supersonic promises to prevent heat damage in users’ hair. The hair dryer combines technologies from other Dyson devices – like the air multiplier tech seen in bladeless fans and the industrial stylings and motors seen in the company’s handheld vacuum cleaners.

The Dyson Supersonic was just previewed to audiences in the UK, where it’s available at a price of £299 (about $440 USD). So it’s probably the most expensive hair dryer you’ll ever purchase.

The dryer has not yet been launched but is preparing for release worldwide later this year.

Is the Dyson Supersonic worth the high price? Let’s take a closer look.

Dyson Supersonic Features

Early rumors about the Dyson Supersonic claimed that the hair dryer would be totally silent. That’s not true: the Dyson Supersonic definitely makes noise, but it’s considerably quieter than any other hair dryer on the market.

Quiet Design Technology

Making a noiseless hair dryer is physically impossible. Dyson explains that you cannot blow air through channels at high speed without making noise.

However, Dyson’s engineers tried to minimize noise as much as possible by tuning the acoustics of the digital motor inside the Supersonic while also increasing the number of blades on the rotor from 11 to 13, helping to modulate one of the vibrating tones to a frequency inaudible to human ears.

What does all of that mean for you? It means you can easily have a normal, human conversation while using the Dyson Supersonic on your own hair (at least, when the device is on the low setting). There are three airflow settings in total, and the loudest airflow setting will require you to raise your voice a little in order to be heard (although it’s still significantly quieter than pretty much any other hair dryer).

To get an idea of how quiet the hair dryer is, watch the video at the top of this Guardian article.

The secret to the noiseless technology in the Dyson Supersonic is a V9 motor that pulls in 13 liters of air every second. Dyson’s proprietary air multiplier technology then increases that to 40 liters of output. So it sounds like you’re sucking in 13 liters of air, but it feels like you’re outputting 40 liters of air.

The airflow is fast and focused. Dyson claims to have optimized the device to create a jet that’s focused enough to dry the hair quickly and safely without damage while still allowing accurate styling.

There are four precise heat settings and three different airspeed settings.


The Dyson Supersonic is probably the most unique-looking hair dryer you’ll ever see.

When you don’t have any attachments on the dryer, it looks kind of like a rubber mallet. It doesn’t have the same long tube as other hair dryers. When you spin the device in your hands and look through it straight-on, you’ll be able to see clean through (kind of like those Dyson bladeless fans).

The hair dryer’s attachments all attach to the device magnetically. With an attachment, the dryer looks more like a conventional hair dryer in terms of shape and size.

The hair dryer is also praised for its balance. The motor is located within the handle of the hair dryer, which makes it easier to control the dryer when hitting hard-to-reach areas of your head. If you’ve ever found conventional hair dryers to be clumsy and awkward, then the Dyson Supersonic should be a nice change.

Temperature Control

Dyson invested a whopping £50 million into the technology behind the Supersonic. Along the way, the dryer was tested on more than 1,000 miles of real human hair from nationalities all over the world.

Clearly, the company invested a lot of that time and money into making sure the dryer did not damage hair. Thus, temperature control is one of the key features in the Supersonic. The Supersonic regulates air temperature 20 times per second, helping to avoid heat damage to your hair.

To measure heat, the Supersonic uses a glass heat thermistor. That thermistor prevents the temperature of the dryer from ever going over 150 degrees Celsius.

Dyson Supersonic Tech Specs

  • 2.7m salon-length cable
  • 1600 watts of power
  • 618g weight
  • 41 liter per second airflow
  • Negative ions to help reduce static
  • 245x78x97mm (Height x Width x Depth)

Dyson Supersonic Pricing

The Dyson Supersonic is priced at £299 (around $440 USD).

That price is enough to turn most people away from the Dyson Supersonic. Considering decent-quality hair dryers can be found for £30 or less, many people will have a hard time justifying this high price tag.

As a testament to the high price tag, your Dyson Supersonic arrives in a hard silver case. Yes, if you’re on a tight budget, then this isn’t the hair dryer for you.

All Dyson purchases come with a 2 year warranty on parts and labor as well as a 30 day money back guarantee.

Should The Dyson Supersonic Be Your Next Hair Dryer?

The Dyson Supersonic is one of the most expensive hair dryers on the market. There’s a reason for that high price tag: Dyson invested $72 million into the dryer’s development over the past four years. There are few hair dryers like the Supersonic in terms of noiseless technology, beautiful design, and temperature control.

The high price ensures that this hair dryer won’t be for everybody. And some people don’t have complex hair needs that require a pricey hair dryer. But for those who are fussy about their hair and want to avoid heat damage, the Dyson Supersonic may be the right option for you.

The Dyson Supersonic release date has not been made public yet but is preparing to launch later this year.
