Dyson Chitosan Pre-style cream Curly to Coily, Rich Conditioning is developed for hair that naturally forms spiral curls and ringlets, tighter corkscrew or S-curls, or closely coiled Z-patterns. Best suited to thicker hair strands that need more intensely nourishing ingredients. Conventional retention products create a glue-like hold between hair strands, leaving hair feeling crunchy. Dyson Chitosan Pre-style cream uses Dyson Triodetic technology to hydrate individual hairs, while locking in styles, for long-lasting hold with a lightweight natural feel. vs. untreated.²vs. untreated hair.
