Dyson Post Style Serum 100ml

Formulated for all hair types, this lightweight serum provides flexible hold with immediate definition and humidity protection.

It conditions hair while locking in its shape with a flexible bond structure that won’t alter your hair’s natural texture.

Chitosan, an ingredient derived from oyster mushrooms, allows each strand to move, flex, and recall its style in unison with the rest.

Each bottle contains the equivalent of four to five oyster mushrooms’ worth of chitosan.
