The only PPD-free way to take grey hair to brown or black at home is plant colour used in two steps: pure henna first, then pure indigo. Henna alone turns grey copper-orange; henna followed by indigo gives dark brown to natural black that builds over two to three applications. Many boxed 'herbal' hair colours still rely on PPD or related synthetic dyes for their dark shades, so read the ingredient list, not the front of the pack.
What PPD is, and why people switch
PPD (para-phenylenediamine) is the synthetic dye that gives most permanent box dyes and many 'black henna' products their fast, dark colour. People who switch usually want three things: no PPD or ammonia, a colour that does not need a skin-lifting developer, and a routine they can do at home. Plant colour meets all three, but it works differently and takes more time, so it helps to know what to expect before the first application.
PPD-free options compared
| Option | PPD-free? | Shade on grey hair | Time per application | What to watch |
|---|---|---|---|---|
| Pure henna alone | Yes, if 100% Lawsonia inermis | Copper to orange-red | 2–3 hours | Will not go brown or black on its own |
| Henna, then indigo (two-step) | Yes, if both are single-plant | Dark brown to natural black | 2–3 h henna + 1–2 h indigo | Takes 2–3 rounds for even grey coverage |
| Henna and indigo mixed in one paste | Yes, if both are single-plant | Light to medium brown | 2–3 hours | Less depth than two-step on stubborn greys |
| Boxed 'herbal' or 'ayurvedic' hair colour | Often not — check the label | Brown or black in under an hour | 30–60 minutes | Fast dark results usually mean a synthetic dye |
| 'Black henna' cones or powders | Usually not | Black within an hour | Under 1 hour | Henna is never naturally black |
How to spot PPD on a label
- Look for p-phenylenediamine, para-phenylenediamine, PPD, toluene-2,5-diamine or 'diamine' in the ingredient list.
- A product that promises black in 30 to 60 minutes from one powder is not pure henna or pure indigo.
- Pure plant colour lists one plant per pack: Lawsonia inermis for henna, Indigofera tinctoria for indigo.
- Check for a batch number with manufacture and expiry dates. The full checklist is in how to read a henna label.
The two-step method for grey hair
1
Patch test. Apply a little henna paste and, separately, indigo paste behind the ear 48 hours before. Plant powders can still irritate some people.
2
Henna first. Mix pure henna to a yoghurt-thick paste and rest it 4–8 hours. Apply to clean, dry hair and leave 2–3 hours. Mixing ratios are in how to mix henna.
3
Rinse with water only. Expect bright copper on the greys. That is the base the indigo needs.
4
Indigo second. Mix indigo with lukewarm water just before use (it does not need resting) and apply the same day or the next. Leave 1 hour for brown, up to 2 hours for black.
5
Wait 48 hours before shampoo. Both colours oxidise and deepen over two days. Read the full method in henna then indigo for natural black.
Expect the colour to move: copper at rinse-out, deeper by day two. Greys take colour slowly, so the second and third rounds are what make coverage even. After that, roots every 3 to 4 weeks.
What result to expect, round by round
| Round | Greys look | Tip |
|---|---|---|
| 1st two-step | Warm brown, some copper on the most resistant greys | Do not judge the colour until day two |
| 2nd two-step (within a week) | Even dark brown | Leave indigo longer if you want black |
| 3rd two-step | Dark brown to natural black, blended with your own colour | Then switch to roots only |
| Root touch-ups | Matches the lengths | Every 3–4 weeks, about half the quantity |
Shade-by-shade timings for greys are in henna and indigo for grey hair. If your hair was dyed with a box colour recently, read henna on chemically coloured hair first. Still deciding which product suits you? See which natural hair colour to choose.

Quick answers
Is there a natural hair colour without PPD that covers grey?
Yes. Pure henna followed by pure indigo colours grey hair dark brown to natural black with no PPD, usually after two to three applications.
Is herbal hair colour always PPD-free?
No. Some boxed 'herbal' hair colours use PPD or related dyes for their dark shades. Check the ingredient list for p-phenylenediamine or toluene-2,5-diamine.
Can I get black hair with henna alone?
No. Henna only gives copper to reddish-brown. Black needs indigo applied over a henna base.
Can I use henna and indigo if I have a sensitive scalp?
Do a patch test 48 hours before every first use. Pure henna and indigo contain no PPD, but anyone can react to any plant, so stop if you see redness or itching.
How long does natural colour last on grey hair?
Henna and indigo stay on the lengths; you only re-apply to new grey roots every 3 to 4 weeks.
