Keratin Complex Infusion Keratin Replenisher. It is formulated with advanced infusion technology. This high Ph replenisher automatically opens the cuticle and enters to infuse Keratin proteins and emollients into the hair. Its deep penetrating action repairs and revitalizes hair during blow drying or ironing and closes the cuticle to entrap nourishment. So not only does it work as a treatment, but also a great protection barrier when using heated tools.
