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

The L’Oréal Pro Dia Color Demi-Permanent Hair Colour 6.84 is a tone-on-tone, ammonia-free colour, designed to work on dark blonde bases with a cool and sophisticated direction. Shade 6.84 is positioned as a dark blonde with a cool mocha reflect, ideal for refining the colour, controlling warm reflects, and creating a more elegant and balanced finish.

When applied to dry hair, the creamy texture uniformly coats the hair fibre, allowing for precise and controlled application. The colour develops progressively, revealing a dark blonde with a cool nuance and a subtle mocha effect, accompanied by visible gloss shine. The hair appears more even, with depth and a refined 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 neutralising unwanted 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 white 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 hair colour offers professional performance with a gentler approach. Suitable for colour maintenance, reflect correction, and shine enhancement on dark blonde hair.

How to Use

You can use any Diactivateur developer with Dia colour (mixing ratio: 1 + 1.5). For best results, we recommend: Diactivateur 6 vol. for a soft colour deposit; Diactivateur 9 vol. for a medium colour deposit; Diactivateur 15 vol. for an intense colour deposit.

Use appropriate disposable gloves. Do not use metal tools (bowl, comb...). Use only the recommended Diactivateur.
In a bowl, applicator bottle, or shaker, mix 60 ml (1 tube) of Dia Color cream and add 90 ml of the chosen Diactivateur developer. Apply to dry hair.

First application: The 20 min development time starts at the end of the application.
Root touch-up: Apply to the root area, start the 20 min development time, then immediately distribute through the rest of the hair to revitalise the colour with a deeper and/or darker result.
Distribute through the rest of the hair after 10 min if lengths and ends are moderately faded.
Emulsify during the last 5 min if the colour is slightly faded.
At the end of the development time, emulsify carefully for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
