Schwarzkopf Keratin Color Permanent Hair Dye 7.7 Medium Auburn — Keratin‑Infused, Up to 100% Gray Coverage

Schwarzkopf Keratin Color 7.7 Medium Auburn is a professional‑quality permanent hair dye that delivers rich, multi-dimensional auburn color while strengthening hair with a three-step bond system.

Designed for at‑home use by people who want salon results, this kit includes a pre-color serum, keratin-infused color cream, developer, and a post-color conditioner to help lock in tone and improve hair resilience. The formula was developed with professionals to provide even coverage, long-lasting color intensity, and targeted care for hair that’s prone to breakage or has been previously colored.

How will this color perform on gray or resistant hair?

This permanent dye is formulated to cover gray hair effectively in a single application and produce a uniform auburn tone. Results depend on the percentage of gray, hair porosity, and previous color treatments, but the formula is built for dependable coverage and consistent shade payoff.

• Up to 100% gray coverage on natural hair.
• Keratin and bonding components improve pigment adherence.
• Works on previously colored hair; may need strand test for best match.
• Use two boxes for long or very thick hair for full root-to-tip coverage.

Will this kit help reduce breakage and keep hair feeling healthy?

The included three-step Bond Enforcing System aims to protect and reinforce hair structure before, during, and after coloring. A pre-color serum with Vitamin B6 and collagen prepares hair, the keratin-infused color treats strands during processing, and the post-color conditioner with K‑Bond Plex helps restore and soften the hair surface.

• Pre-color serum supports smoother application and protection.
• Keratin-enriched color cream helps maintain elasticity during color deposit.
• Post-color conditioner seals cuticles and enhances manageability.
• Reduces combing breakage on damaged hair versus a non-conditioning shampoo.*

How easy is the application and what does the kit include?

The kit is assembled for straightforward at‑home use with clear, step‑by‑step instructions; no salon visit required for standard applications. Everything needed for one full head application is included, and disposable gloves are supplied for a clean process.

• Pre-color serum, developer bottle, color cream, and post-color conditioner included.
• Disposable gloves and easy instructions guide the process.
• Suitable for all hair textures; follow timing on instructions for desired depth.
• Consider two kits for hair past shoulder length or dense hair.

Who is this for? This Schwarzkopf Keratin Color 7.7 Medium Auburn kit is ideal for people seeking a warm, medium auburn shade with professional performance at home—those who want dependable gray coverage, added hair strengthening during coloring, and a long‑lasting, multi-dimensional finish. It’s suitable for natural and previously colored hair, across a range of textures; perform a strand test if you have heavily treated or unpredictable hair history.

Note: Individual results vary with starting color, hair condition, and application technique. Follow all included safety instructions and the strand test to confirm shade and compatibility before full application.
