The science behind hair

Solving real hair problems with innovative engineering.

We're obsessed with researching hair damage

Our mission is to solve problems others ignore – maintaining healthy hair by helping to protect against excessive heat damage. To truly understand hair, Dyson engineers have carried out a microscopic investigation into every hair type.

What's your hair type?

There are three different types of bond that give hair its shape. Some of these bonds allow temporary stretching, tensing and reforming to create new styles. Understanding your hair type can help select the best styling approach and treatment for your perfect style.

Know your roots

Pluck a strand of hair and rub it between your fingers. If it feels like a barely-there thread of silk, your hair is fine. If it feels like a thread of cotton, your hair is coarse.

What's your curl pattern?

There are four main hair types: straight, wavy, curly and coily. Understanding your hair shape allows you to understand how to manage and care for your hair, including how to achieve desired styles.

How to manage damage

Dyson technology not only helps to style hair, but is designed to retain colour, moisture, shine and smoothness. We've explored three key areas surrounding hair health.

1. Breakage

Overexposure to extreme temperatures can weaken the bonds in the hair, making it more prone to breakage.

    Weakening your 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 weaker and less elastic over time.

    Prevention not repair

    Once hair has been damaged, it can't be reversed. Hair can become dry and frizzy and lose hydration. If hair is exposed to temperatures over 230°C it will begin to burn or melt.

    Maintain natural strength

    The Dyson Corrale™ hair straightener offers enhanced styling with less reliance on heat¹ with a precise heating system and Intelligent heat control. Flexing plate technology is engineered to gather hair, helping to create an equivalent style in fewer passes and with less reliance on heat.

2. Moisture

Moisture levels within your hair can vary depending on the humidity levels in your environment. Excessive heat can compromise your hair’s natural moisture balance, by making the hair more porous – gaining or losing water more easily.

Understand moisture retention

  • Two hair pieces being tested for hydration and water retention

    The perfect balance

    If too much water is lost from the hair, it can sometimes feel dry and dehydrated. If too much water is absorbed in the bonds, your style can be disrupted, causing it to drop out. Better moisture balance means better retention.

    Weaker when wet

    Water causes hair to swell and become weaker by up to 42%2, breaking the bonds holding the structure together. This is why the Dyson Supersonic™ hair dryer has been designed with fast drying technology.

  • Hair strands being tested for retention

    Achieve style retention

    Our machines have been engineered by hair care experts to prevent excessive heat damage and safeguard your hair’s moisture balance. This not only supports style retention but helps to protect your hair’s wellbeing.

3. Smooth and shine

Shine occurs when light hits hair strands and bounces off evenly. When hair is damaged, the cuticles can lift, scattering light in multiple directions and making it appear dull.

    Loss in colour pigmentation

    Whether your hair’s chemically dyed or natural, high heat can change its proteins. This can cause the colour to be stripped and appear faded – or even a different colour altogether.

  • Woman using Dyson Airwrap multi-styler with Coanda smoothing dryer

    The Coanda effect

    The Dyson Airwrap™ multi-styler harnesses an aerodynamic phenomenon called the Coanda effect, which is powered by the Dyson digital V9 motor. It uses air to wrap and create curls, rather than extreme heat. Helping to protect your natural shine.

  • Woman using Dyson Supersonic hair dryer

    Align for shine

    New attachments for the Dyson Supersonic™ hair dryer and Dyson Airwrap™ multi-styler help reduce flyaways.3 By bringing longer strands to the front and pushing shorter ones underneath, flyaways are reduced for better alignment and shine.

The Dyson solution

Researched. Tested. Resolved.

Years of research and testing at Dyson’s specialist hair science laboratories have confirmed there are two key factors when styling; temperature and control. Our engineers have established technology that styles without excessive heat.
