Battery expertise delivers Dyson’s unique new hair straightener

Dyson Corrale

He might have wished for a better month to launch a new product, but engineering supremo James Dyson unveiled the Dyson Corrale straightener this month– which cuts damage done to hair by half. And it’s garnering some rave reviews.

The company had to rethink it’s global launch, thanks to COVID-19, instead video streaming the launch from Dyson’s store in Paris.

This is the third hair product the company has launched, following the launches of the supersonic hairdryer in 2017, followed by airwrap hair styler. And if their success, despite their high prices, are anything to go by, the straightener will be a slam-dunk success.

Dyson hair productsThe only hair straightener with flexing plates, the Dyson Corrale straightener features pioneering microhinged plate technology, which flex to shape and gather hair, applying even heat and tension to all the hair strands in every pass, reducing the reliance on heat.

This cord-free  styling tool also features Dyson’s Intelligent Heat Control for precise temperatures, together with 4-cell lithium-ion battery technology.

“Since we first started developing the Dyson Supersonic hairdryer, we have continued to explore the science of style, seeking to understand what makes hair smooth, shiny and glossy, and what makes it dull, damaged and lifeless,” said Mr Dyson, whose has a major manufacturing base in Malmesbury.

“We have been worried about heat damage from flat plate straighteners. Flat hair irons apply tension and heat only on the thickest part of the hair tress, the strands at the edges are not clamped, leaving them slack, unheated and leaving flyaways. It requires multiple passes on the same section of hair tress to give an even look, by which time excess heat may have caused reduced strength and less gloss.

“We discovered that if the plates could conform to the precise profile of the tress, then with each pass we could apply the correct tension to all the hair strands. This means that we get enhanced styling without excessive heat damage. We simply do not need the heat that others apply. We engineered unique flexing plates of magnesium copper, wire eroded to a precise accuracy of 65 microns to adapt to the shape of the hair tress. The copper plates wrap around the tress, applying even heat and tension to all the hair strands, keeping them aligned.

Dyson has been researching into the science of straightening for almost a decade, investing more than £100 million into hair laboratories across the globe and employing thousands of hair scientists, engineers and professionals. These expert teams have studied in detail everything from the structure of hair to airflow dynamics whilst understanding thermal, mechanical and chemical damage – and the subsequent effects on hair.

To straighten hair, a combination of heat, tension and control is required – heat to break the hydrogen bonds in the hair, tension and compression to reshape these bonds and control to apply the heat and tension evenly.

Dyson Corrale insideDyson has developed a complex manganese copper alloy plate, featuring an amalgamation of six metals to provide the optimum flexibility, strength and thermal conduction. Each plate is precision machined to 65 microns – the width of a human hair – and tourmaline edged to produce ionising properties that help reduce static.

It is Dyson’s expertise in battery technology, born from development of cord-free vacuum cleaners, that has informed the cord-free capabilities of the Corrale straightener.

The Corrale straightener fully recharges in 70 minutes and provides up to 30 minutes, cord-free styling. The Dyson Corrale is priced at £399.
