Will it work on light or bleached hair?

It can darken light hair, but henna and indigo results on bleached or very light hair are often uneven. A strand test on a small section first is the reliable way to check.

Can I lighten it later?

Henna-based black is very hard to lift. Bleach often will not remove it and can leave a green or muddy tone, so treat it as a long-term commitment.

Does it cover gray hair?

Yes, gray coverage is one of its main selling points. Gray resistant to dye may need a longer processing time or a second application.

Does it contain ammonia or PPD?

No. The formula is plant-based henna and indigo with no peroxide, ammonia or PPD, which is why many users report less scalp irritation.

The powder is mixed with water into a paste, applied to the hair, and left on for a processing period before rinsing. Expect a longer, messier process than a box dye.

Is it safe for everyone?

Henna and indigo are natural but not risk-free. Do a patch test 48 hours before use, and avoid it if you have had reactions to plant dyes.

About the Organic Jet Black Henna Hair Dye

Organic Jet Black Henna Hair Dye is a plant-based dye that colors hair a deep, dark black. It can take lighter hair to a much darker shade or enhance and maintain the current color. It covers grays naturally. It is made without harsh chemicals, pesticides or GMOs.

The color comes from two powders used in sequence. Organic henna (Lawsonia inermis) is milled into powder and triple-sifted. It forms the red-orange base. Organic indigo (Indigofera tinctoria) is then applied to deepen the color to black. Indigo mixed with henna makes shades of auburn, brown or black, and red undertones usually show in every color except black.

The dye also conditions and adds shine, and it boosts manageability and promotes hair growth. With continuous use it improves overall hair health.
