COLORCHARM Permanent Liquid Hair Color 7NN Intense Medium Blonde — Liquifuse Technology, Up to 100% Gray Coverage

COLORCHARM 7NN Intense Medium Blonde is a permanent liquid hair color formulated with Liquifuse technology to deliver even, fade-resistant coverage and up to 100% gray coverage in a compact 1.42 fl oz tube.

This liquid permanent hair color is designed to penetrate the hair shaft for consistent saturation and predictable results. The formula works with a developer to fuse pigment into the strand, producing long-lasting color with reduced fading. Each shade is part of a color-coded tonal family, so selecting the right neutral blonde is straightforward for both at-home users and professional stylists.

How does COLORCHARM 7NN achieve even gray coverage?

The color uses Liquifuse technology to help pigment saturate and bond with each hair fiber, improving uniformity from root to tip. That targeted saturation helps conceal gray hair and blends it seamlessly into the chosen shade.

• Liquifuse technology for deeper pigment penetration
• Formulated for up to 100% gray blending when used per directions
• Designed to reduce patchiness and uneven tones

What results and longevity can I expect from this permanent liquid formula?

This permanent formula aims for vibrant, fade-resistant color that maintains tone and shine longer than untreated hair. While results depend on hair porosity and aftercare, the product is intended to deliver rich color with improved shine.

• Vibrant, long-lasting color with enhanced fade resistance
• Reported to increase shine versus untreated hair
• Best retained with color-safe shampoos and reduced heat exposure

How do I mix and process COLORCHARM 7NN safely and effectively?

Mix this permanent liquid hair color at a 1:2 ratio with your chosen developer (one part color to two parts developer). Apply to clean, dry hair and follow the timing guidelines: develop for 15 minutes, then continue processing up to an additional 30 minutes according to desired lift and coverage.

• Mix ratio: 1 part color to 2 parts developer
• Initial develop time: 15 minutes; process up to 30 more minutes as needed
• Perform patch and strand tests before full application

What sensory and practical details should I know about the product?
