Neutral Henna – Volume & Shine Hair Powder for All Hair Types

The Neutral Henna by Serge d'Estel Paris is a 100% plant-based hair treatment, composed exclusively of Cassia obovata (Cassia Obovata Leaf Powder) — a pure, natural plant known for its coating, volumizing and purifying properties. Made in Paris, it is a pure treatment that cares for the hair fiber without depositing any color.

This treatment is unique in the Serge d'Estel range: it can be used on its own as a fortifying hair mask, or blended with the range's plant-based hair colors to soften highlights and personalize shades. It does not alter the natural hair color. Its composition is free from added chemical ingredients, for a plant-based treatment that respects the hair fiber.

At Natur'All Hair, we select natural treatments compatible with a consistent natural hair care routine — products that care for your hair in depth with every use.

Why choose this treatment?

Fine and weakened hair needs a natural treatment that strengthens and adds volume without weighing down. Color-treated hair needs gentle maintenance between colorings to prolong brilliance and preserve fiber health. Oily or flaky scalps need regular purifying care that cleanses without stripping.

Serge d'Estel Neutral Henna meets all these needs in a single formula: it coats the fiber, strengthens it and delivers volume and brilliance — while purifying the scalp and integrating seamlessly into a plant-based color routine.

This treatment meets a specific need. It can be used on its own for regular hair care, or integrated into a natural hair care routine for long-lasting results.
