The Ultimate Redken Cover Fusion Guide: Formulas, Shade Charts, & Gray Coverage Tips

Tackling coarse, stubborn gray hair is one of the most common challenges behind the chair or at home. Traditional color lines often leave white hair looking hollow, translucent, or overly warm.

Redken Cover Fusion a low-ammonia, anti-aging permanent hair color line engineered specifically for hair that is 50% to 100% gray.

Whether you’re looking to stock your salon backbar or want seamless gray coverage with rich, natural results, this guide breaks down how Cover Fusion works, how to read the shade chart, and how to formulate popular shades like 8NN and 7NCR.

1. What Makes Redken Cover Fusion Different?

Unlike standard permanent color lines that require mixing a natural base to achieve gray coverage, Redken Cover Fusion features a built-in 100% cover-fusion background.

• Pre-Customized Background Color: Every tube contains a blend of brown and tan background dyes that give gray hair multi-dimensional, opaque coverage without looking flat or "shoe-polish" dark.

• Revitalage Colorbond Technology: Gray and aging hair loses elasticity and moisture. Cover Fusion is formulated with argan oil, ceramides, and cationic conditioners to restore smoothness, shine, and manageability.

• Low-Ammonia Formula: Minimizes scalp irritation and harsh chemically treated odor while lifting up to 2 levels.

2. Decoding the Redken Cover Fusion Shade Chart

Understanding the numbering and lettering system makes formulating fast and predictable.

The Number (Level)

The number indicates the depth of tone from Level 1 (Black) to Level 10 (Lightest Blonde). Cover Fusion focuses heavily on levels 3 through 9 where gray coverage is most frequently needed.

The Letters (Tone)

• N / NN (Natural / Double Natural): Pure, neutral tones for maximum gray opacity.

• NA (Natural Ash): Cool tones to suppress warm/brassy underlying undertones.

• Gi / Gb (Gold Iridescent / Gold Beige): Soft, balanced warm tones.

• NCR (Natural Copper Red): Rich, multi-dimensional warm coppers with full coverage.

3. Spotlight on Top-Converting Shades

Redken Cover Fusion 8NN (Light Blonde / Double Natural)

When dealing with ultra-resistant white hair around the hairline or crown, 8NN is the gold standard. The extra "N" packs high-density natural pigments that completely saturate white strands at a Light Blonde level without pulling overly warm.

Buy direct: Get your hands on REDKEN COVER FUSION 8NN for clean, opaque blonde coverage.

Redken Cover Fusion 7NCR (Medium Blonde / Natural Copper Red)

Formulating copper or red on gray hair can often result in pinkish or hot roots if the base lacks enough brown pigment. 7NCR solves this by fusing warm copper-red tones directly into a rich natural base, giving you rich, vibrant copper results that stay locked in.

Buy direct: Add REDKEN COVER FUSION 7NCR to your color cart for vibrant, warm gray coverage.

4. Mixing Ratios & Processing Best Practices

Achieving 100% gray coverage comes down to precise mixing and processing time:

1. Mixing Ratio: Mix 1:1 equal parts Cover Fusion color to developer.

2. Developer: Always pair Cover Fusion with 20 Volume Redken Pro-Oxide Cream Developer.

3. Processing Time: Process for 35 minutes at room temperature (up to 45 minutes for extremely coarse/resistant gray hair).

4. Important Rule: Do NOT use heat when processing Cover Fusion.

Don't forget developer: Grab genuine REDKEN PRO-OXIDE DEVELOPER to ensure complete pigment development.
