Black Cherry will cover a scattering of grey, but if the shade is used on very grey hair, the result would be a softer mauve. Some people may like this, but you must remember the product was not created to cover grey. If you are very grey, were originally a natural dark and love the Black Cherry shade, it is recommended you firstly apply a flat 6.0 dark blonde permanent colourant to your hair. This permanent shade will give 100% coverage of the grey hair and produce a soft brown depth. Then, when Colour Restore Black Cherry is applied, it will display as a soft but noticeable Cherry Purple.
