Indigo Plant-Based Hair Color – Naturally Darken Hair and Improve Gray Coverage

The Indigo Plant-Based Hair Color by Serge d'Estel Paris is a 100% plant-based coloring treatment, composed exclusively of finely ground indigo leaves (Indigofera tinctoria leaf powder) — a color plant used for thousands of years, known for its darkening, coating and purifying properties.

Indigo is the most versatile shade in the range: it can be used on its own to darken the hair, or mixed with other shades to customize highlights and optimize gray hair coverage. It contains no metallic salts, no sodium picramate, no PPD — a pure plant formula that cares for the hair fiber while coloring. Its composition 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 darkening a color that has lightened over time, improving gray hair coverage on a dark base and restoring density and depth to the base. Indigo responds to these needs in a unique way: it promotes better pigment absorption on gray hairs and can be dosed according to needs for a more or less intense result.

Used alone or blended, indigo deepens the natural color, improves gray coverage and durably enhances the brilliance and visual density of the hair — with a natural, progressive result.

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.

• apply to damp hair (towel-dried), from roots to ends,
• apply a protective cream or vegetable oil along the hairline and ears,
• wrap the hair in a protective film and leave on for 15 to 45 minutes depending on the intensity desired,
