Keratin is what gives our hair shaft the elasticity and resistance to external damage. Results of repeated chemical services can leave hair without keratin. Our new 4Bond technology links these broken bonds and mends hair cuticles from the inside out making your hair stronger and more beautiful than ever! 4Bond achieves truer, richer & deeper color retention and deposit, while infusing & rebuilding the hair strands with Keratin Amino Acids, Hydrolyzed Quinoa Protein & Baobab Protein.

4Bond features four key ingredients infused into a uniquely crafted, easy to use system. It works with not only the newest advanced polymer, but infuses three additional ingredients within the hair shaft to ensure the shiniest, healthiest head of hair possible inside & out during all chemical & color services. 4Bond has been formulated with new protein technology & a never before seen molecular bonding polymer, unlike most brands that utilize a single polymer that only helps rebuild the surface of the hair shaft working primarily with deposition color.
