INDIA, July 2024: Fuelled by the desire to improve everyday technology, Dyson today unveiled the Dyson Airstrait™ straightener – wet to dry straightening with air. No hot plates. No heat damage 1 .

 Engineered for multiple hair types, stylers can achieve a natural straight style, with body and movement, whilst maintaining the strength 2 and healthy look and feel of their hair. The hair tress is contained by two arms, from which a precisely angled high- pressure blade of air is forced downwards and into the hair, both simultaneously drying and straight styling, with one machine.

 “Having a strong understanding of how to manipulate and realise the potential of powerful airflow is fundamental to the performance of the Dyson Airstrait™ straightener. This expertise, which we’ve gained over the last 25 years, is what has enabled us to deliver our first wet to dry straightener, with no hot plates, and no heat damage. Delivering the ease-of-use that people love about straighteners but with high-velocity air blades, saves time, maintains hair strength and achieves an everyday natural straight style.” James Dyson, Founder and Chief Engineer. Airflow. Precision air jets.

 Along the arms of the machine are two 1.5mm apertures. Airflow is accelerated through these apertures, creating two high-velocity downward blades of air. Projected at a 45° angle, they converge to form one focused jet of air, creating the downward force to straighten hair as it dries, with control. This directional airflow helps align the hair strands for a smooth and shiny finish.

 The science behind styling
Dyson has been researching the science of style for over a decade and is investing half a billion GBP to expand and accelerate research and technology development across the beauty category. Dyson engineers 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 change the hair style, hydrogen bonds within each hair strand must be broken and reset to hold a new shape. This can be done with heat or moisture. Styling with powerful airflow from wet, results in less need for high heat, creating less frizz and flyaways 3 and protects natural shine 4 .

 When hair is wet, water naturally weakens these bonds. In this state, the bonds are more elastic and can be reset as hair dries, without using extreme temperatures. By using the optimum level of heat and controlled airflow, we’ve found a way to style hair with less damage. Styling with air allows for the creation of straight styles whilst maintaining volume and movement. Once hair is dry and aligned, the bonds are reset in different ways, locking the new style in place.

 Dyson Hyperdymium™ motor
The Dyson Airstrait™ straightener is powered by the Hyperdymium™ motor – specifically engineered to be at the heart of Dyson’s Hair Care technologies. It is small, light and powerful enough to generate the airflow needed to dry and straighten hair simultaneously, from wet. A 13-blade impeller spins up to 106,000rpm, propelling over 11.9 litres of air through the machine per second. This generates up to 3.5kPa of air pressure, enough to straighten hair as it dries. At 27mm, the motor is small enough to fit in the handle – with no sacrifice on power.

 Intelligent Heat Control
Like the rest of the Dyson hair care range, the Dyson Airstrait TM straightener features an intelligent heat control. Glass bead thermistors measure the temperature of the airflow up to 16 times per second to prevent heat damage and protect hair’s natural shine. This data is sent to the microprocessor which regulates the heating element, ensuring airflow doesn’t
exceed the temperature required.

 Two styling modes. Temperature control.
The Dyson Airstrait™ straightener has ‘Wet’ and ‘Dry’ styling modes, and a ‘Cool’ mode to set the style. The ‘Wet’ and ‘Dry’ modes are pre-set with the specific heat and airflow combination for the best results. In ‘Wet’ mode, choose among three heat settings of <80°C (175°F), 100°C (212°F), and 115°C (239°F). In ‘Dry’ mode, choose between <100°C (212°F) or 130°C (266°F) or a top-up “boost” mode at 130 °C. For airflow control, there are two- speed settings, low flow and high flow, as well as a cold shot and root drying mode.
