2x longer hold.¹ Without the crunch. Refills are only for use with your existing Dyson Chitosan™ Pre-style cream packaging and should not be used in isolation. Shop our full-size product. Retain your styles for longer with Dyson Chitosan™ Pre-style cream. Developed to give 2x longer hold¹, without crunch, stickiness or residue - for looks that last all day, while maintaining natural movement and shine. Dyson Triodetic™ technology, powered by our key ingredient, chitosan, creates flexible, lightweight bonds that support the hair, strand by strand - protecting your style from unwanted frizz, even in high humidity.² Our Curly to coily rich conditioning formula is developed for hair that naturally forms spiral curls and ringlets, tighter corkscrew or S-curls, or closely-coiled Z-patterns. Its richer blend of conditioning agents, including castor seed and argan oils, is best suited to thicker strands, and those that need more intensely nourishing ingredients. Use on damp, towel-dried hair to create a foundation of flexible, all-day style hold. Use alongside Dyson Chitosan™ Post-style serum to prime and define your styles, with flexible hold. Benefits: Flexible, all-day hold. Up to 50% less unwanted frizz. Rigorously tested at 80% humidity. For soft, shiny, smoother hair that lasts.
