Naturtint 4W Radiant Dark Brown is a permanent, ammonia-free hair color that delivers deep, natural dark brown results with up to 100% gray coverage while nourishing hair with plant-based ingredients.

Whether you're covering grays, refreshing faded color, or switching to a richer tone, this salon-quality permanent dye is formulated to blend long-lasting pigment with conditioning botanicals. The package includes everything needed for an at-home application: colorant, developer, after-color care, and clear instructions. Naturtint focuses on safer chemistry—no ammonia, no parabens, no heavy metals—while maintaining durable color performance and a natural-looking finish.

How does Naturtint 4W give long-lasting color without ammonia?

Naturtint replaces ammonia with gentler agents that open the hair cuticle just enough to deposit permanent pigment. The result is resilient color that resists fading while avoiding the strong odor and harshness often associated with ammonia-based dyes.

• Permanent oxidative dyes for deep color retention
• No-ammonia formula to reduce scalp and hair stress
• Conditioning actives help maintain shine and manageability
• Instructions and measured applicator for consistent results

Will this shade cover white or gray hair completely?

Yes—this 4W Radiant Dark Brown shade is designed to cover up to 100% of gray hair when used as directed. Coverage depends on hair texture, porosity, and how thoroughly the product is applied.

• Developer strength balanced for effective pigment penetration
• Even results with careful sectioning and complete saturation
• Follow timing instructions for best coverage consistency

What kind of care and safety features does this hair color include?

• Plant-based extracts to help maintain hair health and shine
• No parabens, no heavy metals; vegan and cruelty-free
• After-color care included to improve softness and manageability
