Herman’s Black Dahlia
Black Dahlia is the ultimate black as a night hair colour, note that if you are light-haired you might need to cover your hair twice, otherwise it might have a dark blue shade in natural light. 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.
