HERBATINT 4N - Chestnut
The Natural (N) series shades colour your hair while keeping its natural colour balance, choose them if you wish to maintain and revive your natural colour.
Colours of the Natural (N) series from 1N to 8N cover 100% of grey hair starting from the first application. Tones 9N and 10N have an extremely low concentration of colouring pigments and thus they must be mixed with a small amount of 8N to obtain the best coverage.
If you wish to use one of the tones of the Ash (C), Golden (D), Copper (R), Mahogany (M) or Flash Fashion (FF) series and you have a high percentage of grey hair, for best results you should mix the colour you have chosen (for example, 4R) with an equivalent shade of the Natural (in this case the 4N) series. As a rule, the higher the percentage of grey hair, the greater the amount of N in the equivalent shade to be used (see the table).
Example: if you have a high percentage of grey hair (more than 60%) and you have chosen to use 4R, we recommend mixing 40 ml of 4N with 20 ml of 4R and complete by adding 60 ml of developer for a right mixing balance between colour and developer 1: 1.
