Dyson Chitosan Post-Style Serum

Dyson Chitosan™ Post-Style Serum is designed to perfect and protect your finished hairstyle with a lightweight, flexible hold and a smooth, glossy finish. Developed to be applied after styling, this advanced serum helps maintain shape, definition, and movement without stiffness or residue.
Formulated with chitosan derived from oyster mushrooms, the serum forms invisible, flexible bonds around each strand to support your style while helping shield hair from frizz, even in high humidity conditions. The result is a natural-looking hold that lasts throughout the day, allowing hair to move freely while staying controlled.
Hydrating ingredients such as hyaluronic acid and conditioning agents help replenish moisture, enhance softness, and improve surface smoothness for up to 24 hours. Hair appears healthier, more polished, and visibly shinier from the first application.
Finished with Dyson’s signature fragrance, the serum delivers a refined sensory experience with green and floral notes, highlighted by sparkling bergamot, soft florals, warm cedarwood, and musk.
Ideal for all hair types, this post-style serum is the final step for achieving a sleek, defined, and long-lasting finish.
