L’Oréal Pro Dia Color Demi-Permanent Hair Colour 4

Tone-on-tone natural brown hair colour without ammonia, with gloss shine and even results

L’Oréal Pro Dia Color Demi-permanent Hair Colour 4 is a tone-on-tone, ammonia-free colour designed to intensify the hair's natural colour with a luminous and balanced finish. Shade 4 is a brown base, ideal for enhancing depth, evening out colour, and restoring shine to lifeless hair.

When applied to dry hair, the creamy texture allows for even distribution, precisely coating each hair fibre. The colour develops progressively, creating a natural brown with subtle reflects and visible gloss shine. The hair achieves a more uniform appearance, with continuity from roots to ends.

The lost melanin replenishment technology acts within the hair fibre, replicating natural colour and filling chromatic irregularities. The result is a truer, balanced colour with natural dimension. Suitable for revitalising faded lengths, enhancing existing colour, or softening the appearance of white hair.

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

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