Dyson Chitosan Pre-style cream Straight to Wavy, Rich Conditioning is developed for hair that's naturally straight, wavy, or has S-wave shape. 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.¹vs. untreated.²vs. untreated hair.
