Collection: Hair Colour

Plant colour works differently from a box dye. Henna stains hair copper; indigo layered over henna takes that copper to brown or black. Neither lifts your natural shade, so where you start decides where you end up, and greys take colour most visibly of all.

Two powders cover all of it. If you are choosing between them, read what henna does and what indigo does first, then patch test 24 to 48 hours before you colour.

Is there a 100% natural hair dye? Plant powders come closest, but the phrase is used loosely on labels — here is what it means in practice.
