Professional demi-permanent colour

L'Oreal Dia Light 5.4 Light Copper Brown is an ammonia-free gel-cream colorant designed for tone-on-tone application on previously coloured hair. The acidic formula uses new acid technology to deliver luminous colour with vinyl shine while conditioning the hair. It is supplied as a 50 ml tube intended for professional use only.

Suitable for colour refresh between permanent

This product suits trained professionals who need to revive vibrancy on normal hair without lifting the base shade. It is not intended for consumers without formal colour training, nor for anyone seeking a permanent colour change, full grey coverage, or a lightening effect on natural hair. Buyers who want a ready-to-use retail dye should look elsewhere.

Consistent performance with correct development

Mixed at a 1 to 1.5 ratio with 6, 9 or 15 volume Diactivateur, the gel-cream processes for 20 minutes to achieve even, predictable deposit. The acidic base maintains hair integrity throughout the development period so shine and condition remain stable from roots to ends. Results depend on accurate mixing and timing by a qualified colourist.
