Ingredients and what they do

• Chitosan — a natural polymer that forms flexible bonds to support the hair strand without stiffening the overall feel, helping to lock styles in place.
• Hydrolyzed Hyaluronic Acid — helps attract and retain moisture while reducing frizz caused by humidity for softness and shine.
• Amino Acids (Panthenol, Arginine, Glycine, Alanine, Serine, Valine, Isoleucine, Proline, Threonine, Histidine, Phenylalanine) — contribute to surface conditioning and hair resilience, supporting a healthier appearance.
• Phyllostachys Bamboo Extract — provides conditioning benefits and helps improve texture for a smoother finish.
• Sodium PCA and Sodium Hyaluronate — humectants that help retain moisture in the hair fiber for a supple feel.
• Fragrance (Parfum) — delivers the distinctive Dyson scent while remaining compatible with styling performance.
• Other conditioning agents and emollients ensure even application and a lightweight, non-greasy result.
