Hair science: At the core of Dyson’s technology
Engineered to support hair shine and prevent damage
-
The hair chemistry behind colour loss
Whether your hair is dyed or natural, applying extreme levels of heat can affect the vibrancy of colour. Conventional tools use extreme heat to style hair – which can damage the outer layer of each strand, allowing the dye to escape and causing natural colour to fade.
The intelligent heat control in-built across our range of hair stylers measures and regulates the temperature to protect strands from heat damage. Conventional hair straighteners work by conforming hair with high levels of heat. A Dyson hair straightener regulates the plate’s heat 100 times per second, supporting hair shine and health. The Dyson hair dryer and Airwrap styler both measure airflow temperature over 40 times per second.

Smooth air supports smooth hair
Control and temperature both factor into styling. Some regular hair dryers rely on heat, propelling uncontrolled airflow which can cause friction, flyaways and frizz. The Dyson Supersonic™ hairdryer uses controlled air output, which allows you to style sections separately and helps to reduce frizzy hair.
The Dyson Supersonic™ hairdryer amplifies airflow to produce a high-pressure stream of air angled at 20°, for precisely directed drying and styling. The curved air produced by the Dyson Airwrap™ styler is achieved through the aerodynamic phenomenon called the Coanda effect. And by gathering hair in flexing copper plates, the Dyson Corrale™ straightener prioritises control over heat, for smoother results without heat damage.
The science inside Dyson’s hair laboratories
-
Hair repair studies tested on real hair
The standard ‘cloth test’ used by others in the industry won’t show the whole picture. By challenging convention we uncovered the role velocity plays in the hair drying process. When controlled airflow is prioritised over extreme heat, water can evaporate off each strand of hair separately. The powerful Dyson digital motor V9 used across our hair tools allows the velocity required for fast and efficient drying.
-
How heat damaged hair is weakened
One in three Australian women use a hairdryer at least once a week. Dyson’s engineers use the tensile test to measure how quickly hair weakened by extreme heat breaks compared to healthy hair. The more heat is used, the more hair is damaged. To reduce frizzy hair and protect hair shine, our tools rely on intelligence over heat.
-
The impact of water on hair repair
The hair chemistry behind water is fundamental to hair health and our engineering. Damaged hair absorbs more water than healthy hair, which can cause the cortex of strands to swell, weakening hair and dulling the colour. The heat control used across our tools helps to prevent this from happening, to maintain and support smooth hair.
The hair science behind style
To perfect the art of styling, Dyson engineers researched the structure of every hair type.
-
How to get shiny hair
When the cuticle of each hair strand is damaged, light scatters throughout the hair in all directions, causing hair to lose vibrancy and look dull. Healthy hair has intact cuticles, allowing light to reflect in a single direction.
To maintain hair shine for every hair type, our tools are engineered to engage with each hair agent, which allows you to shape as you like. We don’t do this with extreme heat – instead, we use intelligent heating to monitor the ideal temperature across every range of hair.
-
How to reduce frizzy hair
Damaged hair can’t be fixed. Maintaining the hair shine you do have and protecting the smoothness of future strands comes down to how you style your hair.
Avoid using extreme heated stylers to shape hair, and style hair from damp to dry, to take advantage of the elastic nature of wettened hair. To combat flyaways, the Dyson Supersonic™ hair dryer comes with a Flyaway attachment to smooth hair.
Hair myths or hair facts?
-
The hair care science of cold water
Hair myth no1. Rinsing hair with cold water is often attributed to improved hair shine – but that’s not science. To protect hair, Dyson engineers looked at each strand at a microscopic level. The hair facts we developed our stylers and attachments with rely on precision and power, to help hair avoid damage from heat.
-
The power of airflow for smooth hair
Hair myth no2. Conventional stylers often use high wattage to attempt powerful airflow – but that’s not science. Instead, our air styling tools use creative solutions for fast drying without damage. The Dyson Airwrap Styler propels hair strands along itself by curving the air around it, helping to smooth hair and create shape. The Dyson Supersonic hair dryer uses air multiplier technology to convert high pressure air into a directed, high-velocity jet.
Hair care science: Did you know?
-
Myth no. 1
Extreme heat can melt hair. At 230°C+, hair bonds begin to break down, burning and melting the structure of each strand. This results in loss of shine, faded colour, breakage and split ends.
-
Myth no. 2
87% of Australian women who use a hairdryer use the tool on the hottest setting. At 150°C+, the outer layer of hair can become compromised.
-
Myth no. 3
Hair strands grow for 2-6 years. Hair damage can’t be reversed, so it’s Important to look after the health of hair. Hair is made up of keratin, water, fats and oils – protect its structure through proper styling and aftercare.
