Korres Argan Colorant 4.0 Brown, Haircolour x 75ml

Select the right colour. The end result depends on the original natural or dyed hair colour. Natural shades provide the ideal coverage for grey hair and allow the most natural result without red shimmer. We should always choose shades that are no more than two shades lighter or darker than the natural colour of the hair. For strands, we recommend a shade that is darker than the darkest existing strands. Instructions for use: Do not use the colouring if the hair has recently been treated with henna or metallic dyes. Wait until the paint has grown out. Reaction time for optimal grey coverage 35-45 minutes depending on hair thickness
