H-Bond Protector is an innovative product that works to protect and restore the hair fiber. The protein serum acts within the cortical matrix of the hair all the way to the outer layers, providing protection and increasing the strength of the hair fiber by up to 40% during chemical processes, particularly oxidative actions. The protein serum and the Enhancer have a bioaffinity with the hair strands and do not interfere with the results or processing time of chemical treatments, reducing damage and harm to the hair fiber.
