Demi-permanent dark blonde hair colour with iridescent golden reflect, ammonia-free for gloss shine and luminous colour
The L’Oréal Pro Dia Color Demi-permanent Hair Colour 6.23 is a tone-on-tone, ammonia-free hair colour, designed for dark blonde bases, delivering luminous and balanced results. Shade 6.23 is a dark blonde with iridescent golden reflect, ideal for enriching colour, softening contrasts, and restoring shine to dull hair.
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 dark blonde with a luminous nuance and visible gloss shine. Hair appears more uniform, with visual lightness and a polished finish from roots to ends.
The lost melanin replenishment technology works inside the hair fibre, replicating natural colour and filling chromatic irregularities. The result is continuous colour, with balanced reflects and no artificial effect. Suitable for revitalising dull hair, enriching reflects, and evening out faded lengths.
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 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, enriching reflects, and boosting shine in dark blonde 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 metal tools (bowl, comb...). Only use the recommended Diactivateur.
In a bowl, applicator bottle, or shaker, mix 60 ml (1 tube) of Dia Color cream and add 90 ml of your chosen Diactivateur developer. Apply to dry hair.
First application: The 20-minute development time begins at the end of the application.
Root touch-up: Apply to the regrowth area, begin the 20-minute development time, then immediately distribute through the rest of the hair to revitalise the colour for a deeper and/or darker result.
Distribute through the rest of the hair after 10 minutes if lengths and ends are moderately faded.
Emulsify during the last 5 minutes if the colour is slightly faded.
At the end of the development time, carefully emulsify for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
