Schwarzkopf Keratin Permanent Hair Dye 1.0 Black Onyx — Salon-Grade, Full Gray Coverage & Bond Enforcing System

Schwarzkopf Keratin Permanent Hair Dye 1.0 Black Onyx is a salon-grade, permanent hair color kit that gives rich, long-lasting black color with full gray coverage while reinforcing hair structure.

This at-home color kit combines a keratin-enriched color cream, a protective pre-color serum, and a restorative post-color conditioner to produce deep, multi-dimensional black tone and visibly healthier-looking strands. The included Bond Enforcing System works across three steps to help reduce breakage and lock in color, while the formula is designed to be easy to apply and suitable for most hair types. For those with longer or thicker hair, two boxes are recommended to ensure complete root-to-tip coverage.

How does this product deliver professional-looking color at home?

The kit contains everything needed for a one-step permanent color service: a pre-color serum, developer, keratin-infused color cream, post-color conditioner, and gloves. Together these components prepare, color, and finish the hair for a consistent result that emulates salon performance.

• Pre-color serum protects and primes the hair surface for even absorption
• Developer and color cream mix to deposit permanent pigment for long-lasting shade
• Post-color conditioner seals the cuticle, adds shine, and helps maintain tone

Will this shade cover gray hair completely?

Yes — the formula is formulated to provide full gray coverage in a single application when used according to directions. It targets resistant gray strands to give uniform, natural-looking results across the hair.

• Designed for up to 100% gray coverage in one use
• Keratin and bond-building ingredients help pigment adhere to the hair shaft
• For very coarse or heavily gray hair, follow timing instructions closely for best results

How does the Bond Enforcing System protect and strengthen hair?

The three-step system combines a protective serum, a keratin-infused dye, and a K-Bond Plex post-color treatment to support hair integrity during and after coloring. These steps are intended to minimize combing breakage and help hair feel smoother and more manageable after processing.

• Pre-color serum with Vitamin B6 and collagen helps protect vulnerable areas
• Keratin in the color cream supports the hair’s structure while depositing color
• Post-color conditioner with K-Bond Plex helps restore and smooth the hair surface

How easy is the application and what should I know before coloring?

Application follows a straightforward three-part routine with clear instructions included in the box. It’s user-friendly for first-time home colorists, but always perform an allergy test and strand test before full application and use two boxes for hair longer than shoulder length.

• Step-by-step instructions included for mixing, application, and processing time
• Disposable gloves provided for a cleaner application experience
• Strand test recommended to preview final color and timing for your hair type

Who is this for? Schwarzkopf Keratin Permanent Hair Dye 1.0 Black Onyx is ideal for anyone seeking a deep, true black shade with professional-level gray coverage and added hair reinforcement. It suits natural and previously colored hair, people wanting to reduce visible grays, and at-home colorists who want a structured system that both colors and cares for the hair. If your hair is very long or particularly thick, plan on using two kits to guarantee even coverage from roots to ends.
