Henna (Mahendi)
More than a dye — a thousand-year-old Indian ritual. What Madayantika is, the colour it gives, and how to use it for natural, conditioning hair colour.
Henna — or Mehendi, as every Indian household knows it — is far more than a hair dye. It is one of the oldest botanical rituals in the country's history: bridal body art in Gujarat, weekly hair care across Rajasthan, natural grey coverage in every state between. Lawsonia inermis leaf powder has been part of Indian life for over a thousand years.
What makes it endure is that it works, it conditions, and it colours naturally — with no ammonia, PPD, peroxide or synthetic chemicals. This guide explains what henna actually is, how it behaves on hair, how to use it well, and what the classical Ayurvedic tradition says about it.
In short
Henna (Mehendi, Lawsonia inermis, classically Madayantika) is a natural leaf-powder hair colour. Pure henna gives a warm orange-red to auburn; for dark brown to black, henna is the first step, followed by indigo. It conditions as it colours, and is for external use only — free of PPD and ammonia.
What is henna powder? The Ayurvedic view
In classical Ayurveda, henna is Madayantika — one of the most documented herbs in Kesha Rakshana, the science of hair preservation. The plant is Sheet veerya (cooling in potency), which in classical thinking makes it traditionally suited to soothing scalp heat and balancing excess Pitta — the dosha classically linked with premature greying and scalp heat.
The Nighantus (classical materia medica) describe Madayantika as Tikta (bitter) and Laghu (light), under the Keshya (hair-preserving) categories — placing henna alongside Bhringraj, Amalaki and Brahmi as a foundational herb of classical hair care.
Henna's colouring property comes from lawsone (2-hydroxy-1,4-naphthoquinone), a natural molecule that bonds with keratin in hair and skin. This is a protein bond, not a surface coating — which is why henna conditions as it colours, the lawsone penetrating the hair shaft rather than sitting on top of it.

Pure henna leaf powder gives a warm orange-red to auburn tone. The exact shade depends on:
- Your natural hair colour (darker hair shows less red; lighter or grey shows more)
- The carrier you use (tea deepens; lemon juice brightens)
- How long the paste stays on (longer = darker)
- How long you let the dye release before applying (longer rest = richer colour)
For dark brown to black, henna is the first step of a two-step system: apply henna first, then follow with Indigo Nili Powder. See our complete guide to Indigo (Nili) for that method.
How to use henna powder: step by step
Preparing the paste
- Measure: about 50–75g for short hair, 100g for medium, 150–200g for long thick hair.
- Mix with your chosen carrier to a thick, smooth paste — the consistency of yoghurt. It should hold shape but not drip.
- Rest the paste 30 minutes to 3 hours for dye release. Longer rest, richer colour.
Application
- Apply to clean, dry hair in sections, roots to tips.
- Cover with a shower cap or cling film to keep moisture and warmth.
- Leave on 1–3 hours depending on intensity.
- Rinse thoroughly with water. Do not shampoo for 24–48 hours — the colour keeps deepening.
Traditional anupan (carrier) guide
| Carrier | Effect |
|---|---|
| Warm brewed black tea | Deepens and enriches colour — the most traditional choice |
| Plain lukewarm water | Standard application, neutral result |
| Lemon juice (small amount) | Helps lawsone release, slightly brighter tone |
| Yoghurt | Adds a conditioning quality to the paste |
| Egg white | Adds protein conditioning, helps hold the paste |
Always use ceramic or plastic bowls. Metal reacts with henna and its carriers and can alter the colour unpredictably.
Henna + Indigo: the complete natural colour system
For dark brown to black, henna and indigo are used together in a two-step process:
- Step 1: apply henna paste, leave 2 hours, rinse and dry completely.
- Step 2: apply indigo paste (mixed with lukewarm water) over the henna. Leave 45–60 minutes. Rinse with water only.
Henna as the warm base, indigo as the deepener — a combination synthetic black dyes approximate but rarely match in warmth. Riddhish Herbals stocks both.
Who can use henna powder?
Henna leaf powder suits adult men and women for external use. A patch test on inner-arm skin 24 hours before the first application is strongly recommended. Those with known plant allergies, scalp conditions or skin sensitivities should consult a physician first. Pregnant and lactating women may use henna externally but should consult their physician. Keep out of reach of children. Results vary from person to person.
Things to keep in mind
- External use only — a cosmetic hair colour.
- Always patch-test 24 hours before the first full application.
- Use pure leaf powder only; avoid "black henna" products, which may contain PPD — always check the ingredient list.
- Use ceramic or plastic bowls, never metal.
- Store cool, dry and sealed; use within about 9 months for best colour potency.

View Henna PowderFrequently Asked Questions
Will henna alone give black hair?
No — pure henna gives a warm orange-red to auburn. For natural black, use henna first, then indigo over it (the two-step method).
Will henna completely cover grey hair?
Yes, very effectively, though grey takes a brighter orange-red than dark hair does. For grey covered in dark tones, follow henna with indigo.
How long does henna colour last?
It fades gradually over 4–6 weeks depending on hair type, washing and sun. It leaves no harsh roots as it grows out — reapply every 4–6 weeks to maintain.
Can I use henna on chemically dyed hair?
Yes, but allow 2–3 weeks after a chemical treatment, and do a strand test first — results can vary with the chemicals previously used.
Does henna condition the hair or just colour it?
Both. Lawsone bonds with keratin inside the hair shaft, so henna-coloured hair often feels stronger with more body. Many report less breakage with regular use, though results vary.
Does henna dry out hair?
Some people find their hair feels drier at first. Using a conditioning carrier (yoghurt or egg) and oiling afterwards usually offsets this; it tends to settle with regular use.
What is the difference between henna for hair and body art?
Both use Lawsonia inermis leaf powder. Body-art paste is mixed with essential oils to boost skin staining; for hair, water or tea carriers are used. Use pure leaf powder for both — never "black henna" with PPD.
How should I store henna powder?
Cool, dry, away from sunlight and moisture, sealed tightly after each use. Air and moisture reduce its lawsone (dye) strength over time.
