Vivitone Oxy-Activator (Crème Developer) is formulated with Amino Function Silicone to help strengthen and protect hair from chemical process.  It is a creamy formula for easy application and deeper penetration.  Vivitone Oxy-Activator recommended for use with Vivitone Creme Color and Prisma Ammonia-free Creme Color.  Amino functioning silicone and a stabilizing agent in the Oxy-Activator formula is guaranteed stability.  

Amino functioning silicone works as follows: A silicone molecule is attached to an amino acid molecule. The amino acid molecule being smaller penetrates into the hair shaft and conditions the hair. The silicone molecule being larger lays on the surface of the hair, which protects the color, lasts longer and leaves hair with incredible shine.
