Ammonia-Free Permanent Colour 6.42

L'Oreal Inoa 6.42 Copper Iridescent Dark Blonde is an ammonia-free permanent hair colour that uses ODS2 technology to deliver deep copper blonde tones. The 60 g tube is designed for professional salon use and provides full white-hair coverage while leaving hair feeling conditioned and radiant.

Professional Mixing and Development

The colour requires precise mixing with a dedicated developer and must be applied by a trained colourist; incorrect ratios or timing can cause uneven lift or unwanted warmth. Development takes up to 35 minutes for up to three levels of lift, and the European shade numbering (6.42/6CV) differs from US charts, so shade selection must be verified before mixing.

Shade 6.42 European System

The single specification that determines suitability is the European shade code 6.42, which identifies a deep copper iridescent dark blonde; buyers needing a different tone, level or numbering system should not use this tube.
