Natural dark brown tone-on-tone colour, ammonia-free, with gloss shine and even results
L’Oréal Pro Dia Color Demi-Permanent Colour 3 is an ammonia-free, tone-on-tone colour developed to intensify natural hair colour with a luminous and balanced finish. Shade 3 is a dark brown base, ideal for enhancing depth and evening out colour without creating an artificial effect.
Upon application, the creamy texture spreads easily, coating each hair fibre evenly. The colour develops progressively, creating a natural result with visible gloss shine. Hair appears more uniform, with visual density and a well-cared-for look from roots to ends.
The lost melanin replacement technology works within the hair fibre, replicating natural colour and filling chromatic irregularities. The result is continuous and balanced colour, with reflections true to the natural shade. Suitable for revitalising faded lengths, reinforcing 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 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, evening out and shine on brown hair.

You can use any Diactivateur developer with Dia colour (mixing ratio: 1 + 1.5). For best results, we recommend: Diactivateur 6 vol. for a gentle colour deposit; Diactivateur 9 vol. for a medium colour deposit; Diactivateur 15 vol. for an intense colour deposit.
Wear suitable disposable gloves. Do not use metallic 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-minute processing time begins at the end of the application.
Regrowth touch-up: Apply to the regrowth area, start the 20-minute processing 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 for 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 water runs clear. Wash with Metal Detox shampoo.
