Say goodbye to greys and hello to​ darkest brown permanent colour that's kind to hair. 100% vegan, ammonia-free gentle hair colour, full of natural ingredients for a super shiny, well conditioned finish. When selecting your shade please note our permanent colour does not contain bleach and will not lighten your hair.

What Josh formulated this for​....gives an expert, natural-looking colour finish and 100% grey coverage. 

Josh’s advice​...if your aim is to cover grown out roots, only apply darkest brown hair colour to the regrowth. Apply a ​Gloss​ to mid-lengths and ends afterwards for a natural, blended finish. Do not apply permanent colour over highlighted or balayage mid-lengths and ends, it will colour over and remove this effect from your hair.

If you have no colour in your hair and want all-over colour, apply permanent colour to your roots and mid-lengths, only colouring your ends for the last 10 minutes of development time for a freshly-coloured salon finish.
