L’Oréal Pro Dia Color Demi-Permanent Colour 5.4

Demi-permanent brown colour with copper reflect, ammonia-free for gloss shine and luminous colour

The L’Oréal Pro Dia Color Demi-permanent Colour 5.4 is a tone-on-tone, ammonia-free colour, designed to work on brown bases with a balanced copper reflect. Shade 5.4 is positioned as a warm-toned brown, ideal for enriching colour, enhancing luminosity, and restoring vitality to dull hair.

When applied to dry hair, the creamy texture uniformly envelops the hair fibre, allowing for precise and controlled application. The colour develops progressively, revealing a subtle copper-reflect brown and visible gloss shine. Hair appears more uniform, with depth and a more vibrant finish from root to tip.

The lost melanin replenishment technology acts within the hair fibre, replicating natural colour and filling chromatic irregularities. The result is a continuous colour, with tone-true reflects and no artificial effect. Suitable for revitalising dull hair, intensifying warm reflects, or evening out faded lengths.

Lasting up to 6 weeks, the colour remains stable and luminous. Coverage can reach up to 70% of white hair, ensuring a natural and blended result. The ammonia-free formula ensures greater comfort during the service and respects the hair fibre.

With up to 92% naturally derived ingredients, this colour offers professional performance with a gentler approach. Suitable for colour maintenance, enriching reflects, and enhancing shine on brown hair.
