Science, not guesswork
At Dyson, we want to know everything there is to know about hair. We're obsessed with the science behind hair and use it to engineer our technology. No guesswork, no gimmicks, just tried and tested science.
What your hair type means for you
Understanding your hair type can help you learn how to define and take care of your hair – and choose the best technology for you. We can roughly categorize 'hair shape' into four main groups. Each is then split into three subtypes – A, B, C – to describe the intensity of the curl pattern, with ‘A’ being the looser shape.

Hair density vs hair thickness
Hair thickness can be made up of two factors – density and strand width. Density is the amount of strands you have, while width is the thickness of the strand.
If you're not sure what strand width your hair is, take a piece and rub between two fingers. If it feels like cotton, your hair is coarse. If you can barely feel it, your hair is fine.
Avoiding exposure to excessive heat
-
Maintaining scalp health
Dyson’s Intelligent heat control helps protect the scalp barrier from excessive heat and maintain its moisture levels. Scalp protect mode in our latest hair dryer adds an extra layer of care for your scalp.
-
Retaining moisture
Excessive heat can make hair more porous – meaning it can gain or lose water easily. The imbalance can weaken hair and reduce style retention.
-
Preventing breakage
Overexposure to excessive temperatures can weaken the bonds in the hair. Losing strength and elasticity over time can make it more prone to breakage.
-
Enhancing shine
Hair can look dull, if damaged, as a result of cuticles lifting and scattering light. But when hair is healthy and aligned, it reflects light evenly – appearing shiny.
