- Keratin Color with K·BOND-PLEX technology is great for mature or brittle hair that needs inner hair structure repair.
- If you have less than 30% gray, choose 1 shade lighter.
- Apply the Pre-Color Serum to your lengths before coloring to ensure an even result.
- For extra caring benefit, leave the conditioner on for up to 15 min., covering with a shower cap.
- If your hair is longer than shoulder length, we recommend using two boxes of Keratin Color hair dye for the application.
