Korres Abyssinia Colour Developing Emulsion Vol.20 (150ml).
The new Korres Abyssinia Superior Gloss Colorant line for professional effects, comes with 3 different colour developers in 20, 30 or 40 vol. These 3 emulsions enable us to light our natural colour 2, 3 or 4 tones. If you want to cover white hair, the lower vol you choose, the stronger coverage you will get. The emulsion 40vol combined with the colorant shades 12.0 and 12.1 can give you a 5 tones lighter result.
In darkening your hair, there are no limits on the developers you choose.
