Dyson is launching a new hair tool for the Supersonic hair dryer, designed to achieve a salon standard smooth finish without using extreme heat.

The new Dyson Supersonic Flyaway attachment harnesses the Coanda effect – first engineered for the Dyson Airwrap styler – to attract and lift longer hairs to the front and push flyaways through the tress to increase strand alignment and enhance natural shine.

To smooth flyaways, professional stylists use a skilled ‘brush and blow dryer’ technique but until now, there was no simpler alternative for everyday stylists, who would turn to high heat solutions such as straighteners to smooth the hair.

To develop the Flyaway attachment, Dyson engineers gathered more than 1.14 billion individual pieces of professional styling data captured from over 10,000 hours of professional stylist trials, observing more than 420 stylists across 80 salons around the world.

Engineers tested a range of angles before reaching the optimum semi-circular curve that gives the Flyaway attachment its distinct shape. Early prototypes feature a closed circular loop, but the bottom of the circle was found to be superfluous.

The new Dyson Supersonic Flyaway attachment is compatible with existing models of the Dyson Supersonic hair dryer. It will be available individually for $99 and in the box of new hair dryers purchased from 5 August for RRP $599.

The new Flyaway attachment will be available when purchasing the Dyson Supersonic hair dryer iron/fuchsia, black/nickel and bright nickel/bright copper on Dyson.com.au.

It will also be available when purchasing the Dyson Supersonic hair dryer iron/fuchsia and black/nickel at David Jones, Myer, Harvey Norman, The Good Guys, selected Bing Lee stores, as well as various hair and beauty retailers.
