Naturigin Permanent Hair Dye 4.0 Brown — 100% Gray Coverage, Ammonia & Paraben-Free

If you want a salon-quality brown that looks natural and nourishes as it colors, this vegan formula is designed for long-lasting vibrancy with gentle, plant-derived ingredients. The kit includes everything needed for an at-home color session in about 30 minutes and aims to leave hair shiny, soft, and evenly tinted. It’s formulated to be suitable for a wide range of hair textures while avoiding harsh chemicals like ammonia and parabens.

How does this brown shade perform on gray or resistant hair?

Shade 4.0 Brown is formulated to give up to 100% gray coverage for most users, producing an even, neutral brown result. The permanent dye system deposits durable pigment while the conditioning additives help the color sit evenly on the hair shaft, reducing patchiness on stubborn gray areas.

• Guaranteed full gray coverage for typical resistant strands.
• Permanent pigment for fade-resistant color lasting several weeks.
• Includes developer and cream for even application.
• Suitable for roots and full-head application.

Will this formula damage or dry out my hair?

The Naturigin formula is created to minimize mechanical stress on hair by excluding ammonia, parabens, and sulfates, and by adding plant oils and aloe to the mix. While any permanent coloring involves chemical interaction, this product focuses on providing color plus care to limit dryness and help maintain a smoother surface.

• Enriched with Argan, Jojoba, and Aloe Vera to boost moisture and shine.
• No ammonia, parabens, or sulfates to reduce harshness during processing.
• Vegan and cruelty-free ingredients for an ethical choice.
• Post-color conditioning included to help seal the cuticle and add softness.

How long do results last and how should I maintain the color?

Expect vibrant, fade-resistant color that can stay rich for up to eight weeks with proper care. Maintenance relies on gentle shampoos, limited heat styling, and periodic conditioning treatments to preserve tone and shine between touch-ups.

• Color longevity up to around 8 weeks depending on hair care routine.
• Use sulfate-free shampoos and color-protecting conditioners.
• Avoid excessive sun and chlorinated water to reduce fading.
• Refresh roots as needed; full recolor timing varies by hair growth and fading.

What’s included in the box and how long does application take?

The kit supplies the color cream, developer, a conditioning post-treatment, and clear application instructions so you can complete the process at home. The entire coloring session is designed to be efficient—about 30 minutes from application to rinse for most users—making it convenient for weekday or weekend touch-ups.

• Colorant cream and developer mixed immediately before use.
• After-color conditioner to help nourish and seal the hair cuticle.
• Application instructions to guide timing and safety steps.
• Average processing time around 30 minutes for standard coverage.

Who this product is for: Naturigin 4.0 Brown is suited to anyone seeking a neutral, long-lasting brown with reliable gray coverage who prefers formulations with plant-derived ingredients. It fits users who want permanent color without ammonia or parabens, those with fine to thick or curly hair types, and buyers looking for a cruelty-free, vegan option that also delivers conditioning benefits during the color process.
