DynamX® polymer is a unique urethane-acrylic film-former designed especially for hairsprays that deliver flexibility with long-lasting hold performance. Supplied as a pre-neutralized hydro-alcoholic solution, it can be easily formulated into hairsprays and other styling aids. DynamX polymer provides a strong, flexible hold with memory (durable hold) that is required for dynamic hairstyles. The hair is able to move freely, yet returns to its original shape, allowing consumers to maintain a freshly styled look throughout an active day. In addition, the polymer offers high shine with thermal protection benefits.
