Dyson's first beauty product is a hair dryer

Dyson teased the event by sending out tiny, sharp motor parts to journalists (including this one), but now we get to see the rest of the thing. Unsurprisingly, the company's first foray into beauty is, perhaps predictably, it's a hairdryer. The Supersonic has all the design hallmarks of a Dyson: it's all circular and smooth, metallic with a splash of loud color. Compared to everything that's come before it, however, it's so... small.

Four years in development, the company spent $71 million (and took four years) to make its hair dryer, with the sort of specifications and research backstory of a car. The press release explains the 600 prototypes , over 100 patents pending, and a cast of 103 engineers that worked on it. It helps to explain the price ($400), but even salon-level hair dryers hover around the $300 mark. Founder James Dyson reckons existing dryers can be "heavy, inefficient, and make a racket."

"By looking at them further, we realized that they can also cause extreme heat damage to hair." He believes the Supersonic solves those issues. Three magnetically-connecting attachments can adjust the output for different hair styles, and include a diffuser and... can you tell I'm out of my depth? Those accessories have a "double skin", so that while the inner part gets hot, the outer stays cool.

However, the engineering jewel inside is a new V9 digital motor, which is Dyson's smallest, lightest motor yet. The company even drafted in a team of aero-acoustic engineers (new career goal) to tinker with the noise the Supersonic makes. The team increased the motors' blades from 11 to 13, which meant that one of the tones made by the motor was shifted beyond audible for humans. Sir James Dyson also noted at the press launch in Tokyo that it rotates fast enough (110,000 rotations per minute) to classify itself as ultrasonic -- if not quite super.

The entire dryer has also been weight balanced for easier handling -- something that isn't usually the case for hair dryers. You'll get to handle one for yourself later this year: the Supersonic will launch in the US exclusively at Sephora this September.
