Henna & Indigo: The Ayurvedic Way to Colour Hair Naturally
Henna and indigo powder are the core of natural hair colouring — henna gives a reddish-brown base tone, and indigo applied afterward deepens it toward brown-black, without the ammonia or synthetic dyes found in chemical hair colour.
Natural hair colouring works differently from chemical dye: instead of stripping and depositing colour pigment in one step, henna and indigo coat and stain the hair shaft gradually, which is why they're often used as a two-step process rather than a single application.
How Henna and Indigo Work Together
Herbal Henna Powder is applied first and gives hair a natural reddish-brown tone while also conditioning it, thanks to added Amla, Bhringraj, and Shikakai. Natural Indigo Powder is applied afterward (not alone) to deepen the colour toward brown or black — using indigo by itself typically gives a greenish or blue-black cast rather than a true black.
Step-by-Step Process
- Mix henna powder with water into a smooth paste and apply to clean, dry hair.
- Leave on for 1–2 hours, then rinse thoroughly without shampoo.
- Once henna has fully oxidized (usually the next day), mix and apply indigo powder the same way.
- Leave indigo on for 1–2 hours, then rinse.
Frequently Asked Questions
Can I mix henna and indigo together in one application?
It's generally recommended to apply them separately, since indigo needs the henna-stained hair as a base to deepen properly — mixing them together often results in a less predictable, greenish tone.
How long does natural hair colour last?
Henna and indigo colour typically lasts several weeks and fades gradually, unlike permanent chemical dyes which grow out at the root.
Will henna and indigo damage my hair like chemical dye can?
No — both are plant-based and traditionally used to condition hair (via added Amla, Bhringraj, and Shikakai) rather than strip or damage it the way ammonia-based dyes can.
How often can I reapply?
Most people reapply every 4–6 weeks as new growth becomes visible, though this varies by hair growth rate and desired colour intensity.
