Perfectly developed to prevent hair breakage.QOD FIBER COMPLEX increases hair strength and flexibility by 7x!. QOD FIBER.COMPLEX is a blend of bio amino acids. It presents a molecular structure that is smaller than the capillary fiber, penetrating into the hair cortex to regenerate stable and covalent bonds, which contribute to reinforce the internal structure of the hair. QOD FIBER COMPLEX also contains glycol ether, that provides fast penetration into the capillary fiber, transporting amino acids for a long-lasting effect. This gradual process ensures homogeneous color and shiny hair – feeding it throughout all chemical hair treatment pause time.
