L’Oréal Pro Dia Color Demi-Permanent Hair Colour 6.31

Demi-permanent dark blonde hair colour with a cool golden reflect, ammonia-free for gloss shine and balanced colour

L’Oréal Pro Dia Color Demi-Permanent Hair Colour 6.31 is a tone-on-tone, ammonia-free hair colour, designed to work on dark blonde bases with a balanced direction between luminosity and reflect control. Shade 6.31 is positioned as a dark blonde with a golden reflect softened by a cool nuance, ideal for maintaining the naturalness of the colour while reducing excessive warmth.

When applied to dry hair, the creamy texture uniformly envelops the hair fibre, allowing for precise and controlled distribution. The colour develops progressively, revealing a balanced dark blonde, with visible gloss shine and a more stable chromatic reading. The hair appears more uniform, with visual lightness and a cared-for 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 true-to-tone reflects and no artificial contrast. It is indicated for softening excessive warm reflects, evening out faded lengths, or revitalising dull hair.

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

With up to 92% naturally-derived ingredients, this colour offers professional performance with a gentler approach. Suitable for colour maintenance, reflect correction, and shine enhancement on dark blonde hair.
