How does this mahogany shade change the look of my natural hair?

4M Mahogany Chestnut tints your base with warm brown and subtle red highlights, creating depth and richness without overly bright copper tones. It can lift natural color by up to two shades for a noticeable but natural transformation.

• Mahogany-brown with natural red undertones for warmth and dimension.
• Designed to blend with the N (Natural) Series for custom results.
• Suitable for subtle lift—up to two shades—in one application.

Will this formula cover stubborn or resistant gray hair?

Yes—Herbatint’s permanent formula is formulated to provide up to 100% gray coverage, including more resistant gray strands. The colorants work alongside eight organic herbal extracts to deposit even pigment while respecting scalp comfort.

• Permanent dye system optimized for full gray coverage.
• Dermatologically tested for sensitive skin compatibility.
• Includes conditioning agents to reduce the brittle feel often associated with gray dyeing.

What safety and ingredient features should I expect?

The formula avoids common harsh ingredients: no ammonia, alcohol, resorcinol, parabens, gluten, SLS, or phthalates. It uses organic herbal extracts to tone and enhance the hair while being cruelty-free, vegan, and packaged with eco-conscious materials.

• Free from ammonia and alcohol for a milder dyeing experience.
• Contains eight organic herbal extracts to support color and texture.
• Vegan, cruelty-free, non-GMO, and packaged in recycled materials.
