IGK Permanent Hair Dye 4N Original Brown — Ammonia-Free Permanent Color Kit | 100% Gray Coverage, Strengthening Shine

IGK 4N Original Brown is a professional-grade, ammonia-free permanent hair color kit that delivers 100% gray coverage while strengthening strands and boosting shine.

Created by salon colorists, this IGK at-home permanent dye combines vibrant, dimensional pigment with a conditioning formula so hair looks polished and healthy after coloring. The kit is vegan, cruelty-free, gluten-free and formulated without ammonia; it’s designed to be easy to use for all-over color, root touch-ups, and gray blending. Key actives like squalane, orchid extract and bamboo extract help hydrate, soften and support hair strength during the coloring process.

How do I get salon-quality results at home with this kit?

The IGK 4N kit uses a colorist-developed system with straightforward application steps to reduce mistakes and produce even, long-lasting color. Follow the included instructions and timing recommendations for consistent outcomes.

• Process for 45 minutes for maximum gray coverage.
• Use for full-head color or precise root touch-ups as needed.
• Do not expect to lighten previously colored hair; it only matches or deepens tone.
• Pair with IGK post-color care for best shine and manageability.

Will this shade cover my gray hair completely?

Yes — IGK’s formula is engineered to deliver full gray coverage when used as directed, producing uniform pigment across treated areas. The developer strength and pigment balance are calibrated to penetrate and neutralize gray fibers effectively.

• 100% gray coverage when processed for recommended time.
• Choose the correct shade to match natural level and undertone.
• For stubborn gray, ensure even application at the root and ends.

Is this color safe for damaged or previously treated hair?

The formula is ammonia-free and enriched with moisture-restoring ingredients to minimize additional stress during coloring. Clinical testing shows improvements in shine, softness and breakage reduction after use, though individual results vary based on hair condition.

• Squalane helps replenish moisture and increase surface shine.
• Orchid extract contributes to smoother, softer strands.
• Bamboo extract supports resilience and helps reduce breakage.
• Works on color-treated and chemically processed hair; do a strand test if hair is weakened.

How do I choose and customize results for my hair type?

IGK 4N Original Brown is suitable for most hair textures and types. When selecting a shade, consider natural level, existing color and desired depth; the kit is best for maintaining or deepening tone rather than lightening.

• Choose a shade 1–2 levels lighter than natural hair only on virgin (uncolored) hair.
• For previously colored hair, pick the same level or darker for predictable results.
• Use for full coverage or partial touch-ups to blend grays and extend salon color life.
• Perform a strand test to preview color and assess timing for your hair.

Who this is for: IGK 4N Original Brown is for people who want a salon-caliber permanent color at home with full gray coverage and added care benefits. It suits anyone looking to maintain or deepen brown tones, protect hair integrity during dyeing, and achieve glossy, smoother-looking results without ammonia. Ideal for users who appreciate professional-grade formulations, cruelty-free ingredients, and easy, reliable application.
