The Amplified?formula for our semi-permanent hair color has 30% more pigment than our High Voltage?Classic hair color!
This formula is not meant for those with commitment issues, as it will last through a few washes. .After Midnight is our deepest, darkest blue hair dye with green undertones. This color can add dark blue highlights to virgin, unbleached hair, but for best results, we recommend lightening hair to a very light level 9 blonde or lighter and toning hair that has yellow tones before use to avoid undesired hues.
