Dyson Chitosan styling products provide flexible hold throughout the day and are formulated for all hair types, complementing Dyson hair care technologies. Available in four distinct formulas, each precisely blended for different hair types and conditioning preferences (rich or light). Powered by Chitosan, its natural properties help hold styles by creating a lightweight, web-like structure around each strand of hair without the stickiness, breakage, or cardboard effect associated with conventional styling products that use simple polymers. This complex macromolecular structure, known as Triodetic technology, allows each strand to maintain its shape while retaining movement. Triodetic technology flexibly fixes style, creating invisible and light bonds between hair strands. Each strand can move, bend, and return to its original style harmoniously with the rest of the hair, resulting in hair that is smooth to the touch without a cardboard effect. The post-styling serum is designed for use on already dry hair after styling. It holds and hydrates your finished style, providing increased shine and definition. Suitable for all hair types, the serum's light texture offers flexible hold without weighing hair down. It contains a blend of amino acids known to repair signs of damage on the hair's surface, and hyaluronic acid to reduce frizz caused by humidity, adding smoothness and shine. Dyson Chitosan Post style serum is developed for use on finished styles on all hair types, delivering 2x longer hold without crunch, brittleness, or residue. It leaves hair looking and feeling moisturized, soft, and smooth. The formula is vegan and paraben-free. Dyson Triodetic technology, powered by chitosan, creates flexible, lightweight bonds that support hair strand by strand. This formula protects your style from unwanted frizz, even in high humidity. For use on dry, styled hair, work through the hair with your fingers to smooth, define, and enhance your style. Use alongside Dyson Chitosan Pre style cream to prime and define styles with flexible hold. Precisely formulated with Chitosan, a powerful key ingredient derived from oyster mushrooms, rigorously tested for the optimum percentage for all-day flexible hold and natural movement without crunch.
