Dyson Chitosan Post-Style Serum — lightweight finishing serum, all-day flexible hold & frizz control (50 ml)

Designed to finish styles without stiffness, this serum uses a chitosan-based technology to form flexible bonds around each strand, helping shapes stay defined and resisting humidity-related frizz. It layers easily over dry, styled hair and includes conditioning ingredients to nourish surface damage, leaving hair soft and touchable with a subtle Dyson signature fragrance.

How does this serum keep styles looking fresh all day?

The formulation builds flexible micro-bonds that support the hair’s shape without creating a crunchy finish. Tested at high humidity, the product helps reduce frizz and maintain hold longer than untreated hair, while preserving natural movement.

• Chitosan forms flexible bonds around strands to lock styles.
• Hyaluronic acid helps manage humidity-induced frizz.
• Lightweight texture avoids weighing hair down or leaving residue.

Can I use it on my hair type and after any styling tool?

Yes — the serum is formulated for all hair types and is intended for application on dry, finished styles. It works as a finishing product after blow-drying, straightening, curling, or air-drying to refine shape and add shine.

• Safe for fine to thick hair — adds definition without stiffness.
• Use after any styling tool once hair is dry.
• Start with 1–2 pumps, add more as needed for thicker hair or stronger control.

What ingredients help repair and protect hair surface?

In addition to chitosan, the serum contains amino acids that target signs of surface damage and hyaluronic acid for moisture retention. These act together to smooth cuticle irregularities and boost shine while keeping the hair soft to the touch.

• Amino acids help address surface wear for a smoother finish.
• Hyaluronic acid reduces frizz caused by moisture in the air.
• Formulation maintains hair’s natural feel while enhancing manageability.

How do I apply the serum for best results?

The bottle includes a precision pump designed to deliver a consistent dose so you can control coverage. Dispense into palms, rub gently to warm the product, then smooth through mid-lengths and ends to refine shape and add shine.

• Use on dry, styled hair; 1–2 pumps to start.
• Sheer between palms before applying to avoid excess product build-up.
• Combine with Dyson Chitosan Pre-Style Cream on wet hair for increased retention when pre-styling.

Who is this for: The Dyson Chitosan Post-style Serum suits anyone who wants a lightweight finishing product that preserves movement while controlling frizz and enhancing shine — from people with fine, easily weighed-down hair to those with thicker textures seeking flexible hold. It’s a good choice for users who want precise dosing, a refined scent, and a refillable full-size option for sustainable re-use.
