Five choices, one plan: grams per step, one step or two, and every timing, each with its source.
When it goes wrong
Orange on day one, a green tint, greys that will not take: the fixes, in plain steps.
- Henna turned my hair orangeWait 24–72 hours for henna to deepen; if it remains too orange, strand-test a second henna layer or a henna–indigo mix, and avoid untested bleach or box dye.
- How to get rid of green tint after indigoA green tint after indigo often comes from using indigo on light or grey hair without a henna base; wait 24–48 hours, then warm it with henna if needed.
- Henna not covering greyHenna may leave grey visible when dye release, paste condition or contact time is inadequate; improve preparation, allow oxidation, then consider another application or indigo.
- Can you use box dye over hennaYou may be able to use box dye over henna, but check which henna you used and test a hair clipping first; colour results can be unpredictable.
