Dyson engineers solve real life, real hair problems. Our challenge for style retention was to create hair styling product formulations that deliver strong hold, with no compromise on the natural look and feel in the hair.

  • Problem

    Some other hair styling products create brittle, glue-like hold between fibres, which can make hair feel stiff and crunchy.

  • Solution

    Dyson Triodetic™ technology flexibly locks in styles, strand by strand, with a lightweight structure between bonds. Hair has a long-lasting, strong hold, while each strand can still move, flex, and recall its style in unison with the rest. The result is hair that feels nourished, without the crunch.

Powered by chitosan

[chi-to-san]: A complex macromolecule derived from oyster mushrooms – our key ingredient to give flexible hold and lasting styles on all hair types.

Engineered to perform

Hold. Movement. Shine. Dyson Chitosan™ formulations give your style 2x longer hold1, while maintaining natural look and feel.

Model with long, shiny, styled hair.

Natural strength

Chitosan is an essential component found in the cell walls of mushrooms, giving the fungi its billowing, cloud-like shape.
