Dark Chestnut Plant-Based Hair Color – Deep Brown Highlights and Brilliance for Chestnut to Brown Hair

The Dark Chestnut Plant-Based Hair Color by Serge d'Estel Paris is a 100% plant-based coloring treatment, formulated from walnut shell powder (Juglans regia seedcoat powder), walnut leaf powder (Juglans regia leaf powder) and indigo (Indigofera tinctoria leaf powder) — three natural ingredients with complementary color properties. Walnut shell delivers warm, natural chestnut tones, walnut leaf deepens the shade and adds softness and brilliance, while indigo provides the depth and dark brown highlights characteristic of this shade.

This herbal hair dye blends with your natural color to gently warm and deepen it, with a natural, luminous result that evolves progressively with every application. Its 100% plant-based formula is free from added chemical ingredients, for a plant-based treatment that respects the hair fiber.

At Natur'All Hair, we only select hair colors compatible with a consistent natural hair care routine — products that color, but also care for your hair with every application.

Why choose this hair color?

Chestnut to brown hair often needs deepening a color that lacks intensity and depth, covering gray hairs with a natural brown veil and restoring density and radiance to the base. Without the right care, these hair types can look dull, flat or without depth.

A well-chosen dark chestnut natural hair dye, on the other hand, deepens and intensifies the color, wraps gray hairs in a natural transparent brown veil and durably improves the brilliance and visual density of the hair — with no helmet effect or visible regrowth line.

This plant-based hair color meets a specific need. It can be used on its own for regular upkeep, or integrated into a natural hair care routine to strengthen results over time.
