GOOD DYE YOUNG Semi-Permanent Hair Colour None More Black 148mL

None More Black was created to be used as a mixer to darken our colours – we do not suggest using None More Black on it’s own. With semi-permanent black dyes, the underlying pigments (blue, purple) can tend to stick to blonde hair, causing the hair to appear dark purple or blue. Mix a few drops of NMB with Blue Ruin to create a navy blue! Mix a few drops of NMB with Rock Lobster to create a maroon! Mix a few drops of NMB with Kowabunga to create a forest green! Mix a few drops of NMB with Ex-Girl to create a magenta!
