Ebony Semi-Permanent Hair Colour Ebony envelops your locks in a lustrous shine with a natural undertone of red. As the darkest colour in our collection, use this shade for a quick cover-up. Please note Ebony is not a pure black colour. For the most vivid results, we recommend applying to pre-lightened hair. The colour on the pot is a simulation of the colour on a level 10. Soft, silky hair never goes out of style. That’s why all our colours contain a conditioning formula that nourishes hair from first application.
