Herbatint Hair Color — 3N Dark Chestnut

Herbatint 3N Dark Chestnut is an ammonia-free permanent hair color with a deep brown tone and soft chestnut warmth. Part of the N, or Natural, series, this coloring gel is designed for a natural, even color result and gray coverage.

Deep brown color with chestnut warmth

The 3N shade pairs a dark-brown base with subtle chestnut warmth. Compare it with 2N Brown and 4N Chestnut when choosing among the darker Natural-series shades. Herbatint recommends identifying your natural shade at the roots rather than relying on previously colored lengths.

A color strand test gives you a preview on your own hair before a full application. Test a section that includes the colors you want to cover, following the package directions. This is separate from the skin sensitivity test.

Natural-series gray coverage

Herbatint identifies Natural-series shades 1N through 8N as its full gray-coverage range. The 3N Dark Chestnut shade falls within that range. Follow the instructions carefully, including the processing time, rather than assuming the color name alone determines the result.

This is permanent coloring gel, not a wash-out concealer. If you want temporary coverage between color sessions, compare the Dark Chestnut Root Touch-Up Kit, which is applied without developer and removed with shampoo.

Mixing and applying the permanent gel

Mix equal parts color and developer in a plastic or glass container, never metal. The amount needed depends on hair length and volume. Mix with a brush until the gel is consistent, then apply to dry, unwashed hair starting at the roots. Herbatint specifies a 40-minute processing time; follow your package's instructions for full-head or regrowth application.

After processing, rinse thoroughly with your head tilted back to avoid contact with the eyes, then shampoo and condition as directed. Store only unmixed color and developer as the manufacturer directs; do not save a prepared mixture for another application.

Sensitivity testing and coloring precautions

Perform Herbatint's sensitivity test 48 hours before every use, even if you have colored your hair before. Ammonia-free does not mean allergy-free, and a sensitivity test does not guarantee that a future allergic reaction will not occur. Read the current ingredient list and all package warnings before use.

Herbatint's stated lightening limit is up to two shades on natural, untreated hair. Do not expect the same lightening result on previously colored lengths. Browse the Herbatint collection to compare shades and application accessories before choosing your routine.
