How Dyson is revolutionising scalp care with its latest haircare innovation

Dyson has launched its most intelligent hair dryer to date in the UK, designed to champion scalp health with new sensor technology.

Following its launch into the world of haircare in 2016, the brand has introduced the next iteration of its Supersonic Hair Dryer, the Nural.

The new styling tool promises to protect scalp health and enhance hair’s natural shine with "fast, intelligent drying and no heat damage for all hair types".

The innovation behind the Supersonic Nural

The latest launch is defined by a new scalp protect mode, which automatically reduces heat and airflow as it nears a user's scalp, helping to protect their hair and scalp from damage.

As part of this, heat is automatically reduced to 55°C - "the optimum temperature for scalp comfort and drying speed" - as the tool gets closer to the hair and scalp. A time-of-flight sensor enables this, by projecting an invisible infrared beam to measure the distance between the tool and the user's hair.

Meanwhile, capsule illumination changes colour to show each heat setting. This feature ensures that the LED light colour will automatically change from cool blue or yellow (low heat) to orange (medium heat) and red (high heat), depending on the distance the machine is from the head.

"From our research into the science of hair, we know that there is a connection between the quality of hair and a healthy scalp," said Shawn Lim, Head of Research at Dyson.

"The scalp tissue comprises different layers, with the outermost layer serving as a barrier against external stressors. But when your scalp is damaged, moisture loss can occur, a key factor in our development of the scalp protect mode feature. This helps to maintain scalp moisture levels and allows for gentle drying."

Other innovations include attachment learning, which remembers styling preferences to simplify routines as it adapts to a user’s "go-to" styling mode, remembering their last-used heat and airflow settings for each styling attachment and automatically applying them the next time it is in use.

It also boasts a motion-sensing accelerometer, which automatically deactivates the heater, decreasing airflow and noise when a user is in between styling passes.

The innovation behind the Supersonic Nural is celebrated in its design, with a clear end cap showcasing the technology inside. This is complimented by the brand's Ceramic Patina and Topaz and Vinca Blue and Topaz colourways.

It follows Dyson's plans to launch 20 new beauty products by 2026 as part of a £500 million investment to accelerate research and technology development across its beauty portfolio.

The investment, announced in October 2022, is also creating new lab spaces to help sharpen Dyson’s understanding of global hair types and damage, as well as supporting the continued diversification of the brand's beauty technology.

Dyson has built up a reputation in the haircare technology market in recent years. Eight years ago, the brand first launched its Supersonic hairdryer, which uses fast airflow and intelligent heat control to quickly dry hair whilst keeping it strong and healthy.

Since then, it has developed a whole range of styling tools engineered to provide styles for all hair types, limiting exposure to extreme heat damage. This includes the Dyson Airwrap multi-styler, which is often sold out online.

More recently, Dyson also introduced the Airstrait, which straightens hair from wet to dry using air, as well as the Supersonic R, designed specifically for professionals.

"Innovation only comes from investing in research and development. Our obsession to truly understand the root of the problem continues as we build up some of the most sophisticated hair laboratories in the world," said James Dyson, Founder and Chief Engineer.

Priced at £399.99, the Supersonic Nural is now available in the UK.
