Keratin Complex KC Primer Pre-Treatment Shampoo

Treatment Shampoo is a powerful yet gentle cleansing shampoo that prepares the cuticle for optimal uptake of proprietary Signature Keratin. KC PRIMER was designed to work synergistically with NKST, NKSTB, EBO and PBO and is the necessary first step in the treatment protocol. BRAND NEW, UNOPENED. I have more than one available.
