b3 Brazilian Bond Builder is a professional, one-step tool that can be mixed into any color formulation to help re-attach and build bonds. This scientifically advanced system reattaches and builds the bonds that make up the cellular membrane complex, helping prevent the loss of cuticle and cortex cells responsible for supporting the inner structure of the hair. It also helps to improve the overall integrity of the hair while prolonging color retention and vibrancy between appointments.
