Key features
- Permanent colour: Lifts and deposits pigment for long-lasting tone change.
- Up to 100% grey coverage: Reliable performance even on resistant grey hair.
- Doubled-intensity construction: The repeated "66" denotes amplified intensity at depth — designed for vivid, saturated reflect.
- High-shine cream formula: Conditioning agents help hair feel mask-treated after rinsing.
- Mixing ratio: Combine with Revlonissimo Creme Peroxide developer at the ratio recommended by Revlon's technical guide for the desired lift and coverage.
Shade — 66.40 Intense Copper
"66" denotes a dark blonde depth at amplified intensity; ".4" denotes the primary copper reflect; ".0" indicates no secondary reflect. The result is a glowing, saturated copper — a confident, statement-making warm tone that catches light vividly and refreshes faded copper colour for longer.
Who it's for
Designed primarily for use by professional stylists in salon. Best on existing dark-blonde to medium-brown bases. Particularly suited to clients with warm or olive skin undertones who want a vivid, saturated copper. Not designed for use on eyebrows or eyelashes.
