This hair color range provides 100% gray coverage with a natural, radiant finish. The advanced 3-step Bond Enforcing System includes a protective pre-color serum with Vitamin B6 and collagen, a keratin-infused color cream, and a post-color conditioner enriched with K-Bond Plex. These steps reinforce the inner hair structure, reduce breakage by up to 80%, and leave your hair 5X stronger*. Suitable for refreshing previously color-treated hair. This at-home color kit is designed for all hair types and textures, and it includes everything you need. With easy-to-follow instructions, you’ll get long-lasting, fade-resistant color that stays true to tone.
