Naturtint 4NM Intense Brown is a permanent, ammonia-free hair color that delivers rich, natural-looking brown tones with up to 100% gray coverage while conditioning hair with plant-based actives.

Whether you want to refresh your natural shade or cover greys, Naturtint’s 4NM Intense Brown offers salon-caliber results at home. Formulated without ammonia, parabens, or heavy metals and certified USDA BioPreferred and ISO 16128 compliant, this dye combines long-lasting pigment with botanical extracts to help hair feel smoother and look shinier after coloring. The kit follows cruelty-free, vegan standards and is designed for easy, low-mess application for both first-time users and experienced home colorists.

How does Naturtint 4NM deliver natural-looking, even color?

The formula uses carefully selected permanent dyes blended with plant-derived conditioners to deposit consistent pigment from roots to ends. Because it’s ammonia-free, the lift and deposit process is gentler, helping maintain hair texture and reducing the odds of brassy tones.

• Permanent dye system for long-lasting color retention
• Ammonia-free base to reduce harsh odor and preserve hair feel
• Even pigment distribution for smooth, uniform shade
• Suitable for grey blending and natural shade enhancement

Will this shade cover my greys and how long does it last?

4NM Intense Brown is formulated to provide up to 100% gray coverage on a range of hair types. Longevity depends on hair porosity, aftercare, and frequency of washing, but the permanent pigments are designed to remain vivid until new growth appears.

• Designed for full grey coverage when used per instructions
• Permanent result lasting until natural regrowth
• Color retention improved with sulfate-free shampoos and cold rinses
• Touch-ups recommended for visible root regrowth
