It's Pure Org Herb Hair Indigo Black - 100g

100% Organic Indigofera Tinctoria (Indigo) Leaf Powder.

To check the colour, we recommend you strand test a small section of your hair before applying to your entire head.

A few other things to bear in mind:

Leaving the paste on for a longer time will make the colour stronger. If you want a deeper colour, you can also build up the colour with a second application.

The true colour takes a few hours to develop. When you first wash out the dye it will often not be the full depth of colour, but it will gradually darken to its true colour. Like a cut apple - at first the apple is white and then as it oxidises in the air it goes brown.

If your hair has been chemically lightened it will affect the colour result. - Chemical lighteners make your hair more porous and thus absorb the colour less predictably.

It is not recommended to use chemical bleach after using this dye unless it has faded or grown out. This is because bleach will not remove indigo so you may be left with a bluish colour.
