Chitosan is the hero ingredient in our Dyson Chitosan™ hair styling range. Chitosan is a complex macromolecule derived from oyster mushrooms. This complex macromolecule helps create flexible bonds that support hair strand by strand, for flexible all-day hold¹, even in high humidity.² It’s the foundation of our Dyson Triodetic™ technology. Our key ingredient is also supported by oils for a formula that helps condition the hair surface, reducing frizz and giving a soft, shiny finish.
