Hair science: At the core of Dyson’s technology

Styling that supports hair repair – possible through Dyson’s innovative engineering.

  • 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.

How to manage heat damaged hair

Dyson technology is designed to style hair and simultaneously retain colour, moisture, shine and smoothness. We've explored three key areas of hair science to improve everyday hair health.

Protect hair from breakage

For how to repair damaged hair, learn how to protect it in the first place.

  • Weakening your hair

    A demonstration of how heat affects hair

    Exposure to temperatures over 150°C can cause the shape of the keratin in hair strands to change. The α-keratin slowly converts to β-keratin, which makes hair less elastic over time, leading it to break.

  • Prevention, not repair

    The technology behind a Dyson Supersonic hair dryer

    Damaged hair can’t be reversed. Once altered, hair can become dry and frizzy. If hair is exposed to temperatures over 230°C it will begin to burn or melt. To reduce frizzy hair, maintain the strength of strands by using supportive stylers.

  • Maintain natural strength

    In place of extreme heat, Dyson’s tools offer enhanced styling with half the damage. Intelligent heat control, precision styling and advanced materials help to create equivalent styles with less reliance on heat. The looks you love, without heat damaged hair.

Understand moisture retention

  • The perfect balance

    Moisture loss can result in dulled colour, breakage and brittleness – but too much water is also a bad sign. Strands which become ‘bloated’ with water can feel dry and dehydrated, leading to the same concerns. Better moisture balance means better retention – which helps to reduce frizzy hair.

  • Wet hair is weak hair

    Wet hair is weakened by up to 43%, as strands swell, breaking the bonds which keep structure in place. Dyson’s Supersonic™ hair dryer has fast drying technology, to help hair stay smooth and shiny.

  • Achieve style retention

    Our stylers have been engineered with the help of hair care experts to prevent heat damaged hair and safeguard moisture balance. This not only supports style retention but helps to protect your hair’s wellbeing.

Maintain natural shine

  • Colour pigmentation loss

    Heat damaged hair is visible through colour changes. Both dyed and natural pigments are affected by extreme heat – as the proteins are altered. This causes colour to fade or alter over time.

  • The Coanda effect

    An aerodynamic phenomenon, the Coanda effect is built into the Dyson Airwrap™ multi-styler. With the help of the Dyson digital V9 motor, it harnesses air rather than heat to wrap and create curls, supporting hair repair journeys.

  • The hair science behind smoothness

    The new attachments in the Dyson Supersonic™ hair dryer and Dyson Airwrap™ multi-styler uses airflow to reduce flyaways. By bringing longer strands to the front and pushing shorter ones underneath, Dyson’s tools reduce frizzy hair and enhance smoothness.

The Dyson Solution

Dyson’s specialist hair science laboratories have devoted years of research to key styling factors. To prevent heat damaged hair, our engineers established technology that prioritises control over excessive heat.

Attachments and accessories

Dyson-designed hair care attachments and accessories are researched and tested on real hair, to ensure they’re inclusive of all hair types.

  • Re-engineered Diffuser

    Captures curls and reduces frizz without disrupting hair's natural form. Re-engineered with longer prongs to reach deeper into the hair and evenly diffuse each curl, helping to achieve definition and shine.

  • Flyaway attachment

  • 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.
