PARIS, FRANCE. 10 MAR 2020. Powered by a relentless approach to research, experimentation and testing, coupled with the desire to constantly re-engineer and improve every day technology, James Dyson has today unveiled the Dyson Corrale™ straightener – the first and only straightener with flexing plate technology that delivers enhanced styling with half the damage¹.

The 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 and keeping them perfectly aligned, reducing the reliance on heat.

Suitable for all hair types, this unique styling tool also features Dyson’s Intelligent Heat Control for precise temperatures, together with 4-cell lithium-ion battery technology to deliver cord-free performance, allowing users to achieve outstanding style anywhere at any time.

“Since we first started developing the Dyson Supersonic™ hair dryer, 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. We have been worried about the style results and 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 and without excessive heat damage. We simply do not need the heat that others apply. We engineered unique flexing plates of manganese copper, wired 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.

The Dyson Corrale™ straightener elevates styling results, while dramatically reducing the heat damage on hair.”

- James Dyson, Founder and Chief Engineer

Science of Styling

The Dyson Corrale™ straightener has been engineered to provide outstanding styling, ensuring hair is better protected and maintains a smooth and glossy finish. Dyson has been researching into the science of straightening for almost a decade, investing over £100m 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 health.

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’s extensive testing highlights that flat plate straighteners can only apply heat and tension to the thickest part of the tress and this means that towards the edges of the tress there are loose strands which are not treated or tensioned. These become flyaways and are only brought into the tress through repeated passes. These repeated passes may cause unnecessary heat damage, which in turn may cause a reduction in hair strength, gloss and colour.

Pioneering Corralling Plate Technology

Dyson has developed a complex manganese copper alloy plate, featuring a carefully balanced 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.

Unlike traditional straighteners, the unique flexing plates of the Dyson Corrale™ straightener mould to shape and gather the hair, giving the user greater control and therefore elevating styling, whilst reducing the reliance on heat. As the plates adapt to the hair, they apply tension more evenly and stop strands splaying. This greater control allows outstanding styles to be created with less reliance on heat, reducing damage by 50%.

Intelligent Heat Control

The Dyson Corrale™ straightener has three precise heat settings – 165°C (330°F), 185°C (365°F) and 210°C (410°F). These temperatures allow the user to tailor the settings to suit their hair type and desired style. This adaptability, combined with the increased control provided by the flexing plates, allows users to style at lower temperatures without compromising on the results.

Dyson hair scientists found that although temperature settings are present across the majority of conventional straighteners, the real time temperature being delivered from the plates can fluctuate significantly as the elements within the straightener respond to power source.

Much like the Dyson Supersonic™hair dryer and the Dyson Airwrap™ styler, the Dyson Corrale™ straightener features Intelligent Heat Control technology. Using a platinum sensor, the temperature is regulated 100 times a second. This technology communicates with a microprocessor which in turn controls the heating system delivering precise, accurate heat.

Four Cell Lithium-ion Battery

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 Dyson Corrale™ straightener. 

Powered by a four-cell lithium-ion battery, the Dyson Corrale™ straightener delivers the same thermal performance of a corded product with the cord-free versatility and universal voltage allowing users to style anywhere, anytime. A flight mode feature also ensures the device meets air travel standards and can be packed in cabin luggage for travel³.

The Dyson Corrale™ straightener fully recharges in just 70 minutes and provides up to 30 minutes², cord-free styling wherever you are. Placing the straightener into the ergonomic charging dock at regular intervals whilst styling or alternatively attaching the magnetic 360° charging cable provides a hybrid charge mode for longer styling sessions.
