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. Ultra Violet is a super cool, blue-toned violet hair dye that can even give unbleached hair violet tones. For the most vibrant results, we recommend lightening hair to very light level 9 blonde or lighter before use.
