Hair colours

The NOAH colours guarantee the coverage of white hair from the first application; for better results we recommend the following:
– With less than 50% of white hair, use a shade similar to yours to keep your color;
– With more than 50% of white hair, use a shade with a darker tone to achieve your color.
