Herman’s Mathilda Granny Grey
Mathilda Granny Grey is our darkest shade of grey that will leave your silky dark silver. Leave hair colour in for 30 minutes or more intense, longer-lasting results, leave the colour in for 1-2 hours, and don’t worry, conditioner hair colour will not damage your hair, but deep conditions it.
