Engineered for flexible, all-day hold1, Dyson Chitosan™ Post-style serum works to preserve your beloved styles for longer – even in high humidity.3

The hero ingredient in this hair styling serum is chitosan, a complex macromolecule that comes from oyster mushrooms. Chitosan enables our Triodetic™ technology to create malleable bonds that support hair strands, for flexible all-day hold with natural movement through high humidity.3 The Dyson Chitosan™ Post-style serum also harnesses the hydrating properties of hyaluronic acid to soften and moisturise the hair. 

Dyson Chitosan™ Post-style serum should be applied on dry, styled hair – whether that be curly, coily, wavy or straight. Use your fingers to disperse the hair serum through your mid-lengths and ends, enhancing and smoothing your finished style.
