Henna vs Mehndi: Are They the Same Thing?

People ask whether "henna" and "mehndi" are two different things. Short answer: they're the same plant and the same dye — the words just come from different languages and are used in slightly different ways.

In short:

• Henna and mehndi are the same plant — Lawsonia inermis — and the same natural dye (lawsone).
• "Henna" (Arabic origin) usually means the plant, the powder, the dye, and hair colour.
• "Mehndi" (Hindi / Sanskrit origin) usually means the body-art designs and the pre-wedding ceremony.
• Both words are correct for the paste and the stain, and are interchangeable in everyday use.
• "Black henna" is not henna — it contains PPD or hair dye and can cause chemical burns and lifelong allergy.

Is henna the same as mehndi?

Yes. "Henna" and "mehndi" are two names for one plant — Lawsonia inermis — and its natural dye. "Henna" is the older, Arabic-rooted word and leans towards the plant, the powder and hair colour; "mehndi" is the Hindi and Urdu word and leans towards the body-art designs and the pre-wedding function. The paste, the stain and the chemistry are identical. If someone asks "is henna and mehndi the same thing", the answer is yes.

Same plant

Both words refer to Lawsonia inermis, a flowering shrub grown across North Africa, the Middle East and South Asia. Its leaves are dried and ground into a powder that contains lawsone, a natural dye. Mixed into a paste and applied to skin or hair, lawsone binds to keratin and leaves a reddish-brown stain. That's true whether you call it henna or mehndi.

Different words

• Henna comes from the Arabic ḥinnā'.
• Mehndi comes from the Sanskrit mendhikā, via Hindi/Urdu.

English borrowed both. Roughly:

• "Henna" tends to mean the plant, the powder, and the dye — "henna powder", "henna for hair", "body-art-quality henna".
• "Mehndi" tends to mean the decorative art and the occasion in a South Asian context — "bridal mehndi", "the mehndi ceremony", "mehndi designs".

But this isn't a rule. Plenty of people say "henna designs" and "mehndi cone" interchangeably, and both are correct.

Regional usage

• South Asia (India, Pakistan, Bangladesh, Nepal, Sri Lanka): "mehndi" for the body art and the pre-wedding function; "henna" also understood.
• Middle East, North Africa: "henna" for both the plant and the body art.
• West / diaspora: "henna tattoo" is common for the temporary design (though it's a stain, not a tattoo — see henna tattoo guide).

What it is not

Whatever you call it, real henna/mehndi:

• Stains orange first, deepening to brown or maroon over 24–48 hours (the colour timeline)
• Is never jet-black, and never stains fully in an hour
• Contains only henna powder, a mild acid, sugar and an approved essential oil (what's in a henna cone)

"Black henna" — which promises a fast black stain — is not henna. It contains PPD or hair dye and can cause chemical burns and lifelong allergy. Read natural henna vs "black henna".

Henna for skin vs henna for hair

Same plant, same dye, different use:

• Skin (mehndi): a temporary stain, 1–2 weeks, fades as skin exfoliates.
• Hair: effectively permanent colour and conditioning — it doesn't wash out, it grows out. See henna for hair.

Other words for the same thing

You'll also hear:

• Mehendi / mehandi / mehndhi — alternative English spellings of mehndi.
• Henné — French; common in North African contexts.
• Hina — the Japanese and older English rendering of the Arabic.
• Marudhani / maruthani — Tamil.
• Mailanchi — Malayalam.
• Gorintaku — Telugu.

All refer to Lawsonia inermis and its dye. Regional plant names don't change what's in the cone.

Quick reference

Why it matters for buying

The label on a product tells you more than whether it says "henna" or "mehndi". What matters is the ingredient list — body-art-quality henna is just henna powder, a mild acid, sugar and an approved essential oil. If a "mehndi cone" or "henna tattoo kit" promises black colour in an hour, that's a chemical product regardless of the name on the box. See how to choose henna cones.

A short history

Henna has been used for body decoration and hair colouring for thousands of years across ancient Egypt, the Middle East, North Africa and South Asia — there's evidence of henna-stained nails on mummified remains, and it appears in South Asian texts and art going back centuries. The South Asian bridal tradition of intricate hand and foot designs, and the pre-wedding mehndi function, developed within that long history. "Mehndi" as the name for that tradition, and the elaborate style associated with it, is the South Asian branch of a much older, wider practice.

How the stain works (both words, same chemistry)

Henna leaves contain lawsone. Mixed into a mildly acidic paste and rested, the lawsone becomes available to bind skin and hair keratin. On skin it produces a temporary surface stain (orange → maroon-brown over 24–48 hours) that fades as skin exfoliates. On hair it's effectively permanent because hair doesn't exfoliate. Nothing about that changes depending on whether you call it henna or mehndi — see what's in a henna cone and the henna stain colour timeline.

So which word should you use?

Either. If you're booking a pre-wedding function in Bangalore, "mehndi" is natural. If you're buying powder or cones, "henna" is common. Hennaya hand-rolls natural henna cones and makes hair henna in Bengaluru, with delivery across BTM Layout, Jayanagar, Koramangala, HSR Layout and Indiranagar, and runs henna classes — call it what you like; it's the same craft.
