Hair Color for All – Indigo Dark Blue

Natural Blue-Black Hair Color with 100% Plant-Based Indigo

If you're looking for a deep, cool-toned black without harsh chemicals, Indigo Dark Blue offers a plant-based alternative to traditional black box dyes.

Made from finely triple-sifted indigo leaf powder (Indigofera tinctoria), this herbal hair dye delivers a natural blue-black tone on most hair bases. It can be used on its own to deepen color or as the second step in a two-step henna + indigo process for improved gray coverage.

Why Use Indigo for Natural Black Hair Color?

Many people searching for natural black hair dye or blue black hair color want rich depth without dryness, irritation, or long-term damage.

Indigo helps:

✔ Create a deep blue-black tone
✔ Darken red or brown henna results
✔ Improve gray coverage with a two-step method
✔ Reduce warmth from previous henna applications
✔ Add cool-toned depth to darker bases
✔ Support smoother-looking hair

When used after pure henna, indigo binds to the warm base layer to create a long-lasting dark shade with a natural finish.
