Dark blonde demipermanent coloration with an iridescent cool reflect, ammonia-free for neutralisation and gloss shine
The L’Oréal Pro Dia Color Demipermanent Coloration 6.12 is a tone-on-tone, ammonia-free coloration, designed to work on dark blonde bases with a cool and controlled direction. Shade 6.12 is positioned as a dark blonde with an iridescent cool reflect, ideal for neutralising warm reflects and creating a softer, more even and natural finish.
When applied to dry hair, the creamy texture evenly coats the hair fibre, ensuring precise and consistent distribution. The colour develops progressively, revealing a dark blonde with a subtle cool nuance and visible gloss shine. The hair appears more even, with controlled depth and a polished finish from root to tip.
The lost melanin replenishment technology acts inside the hair fibre, replicating the natural colour and filling chromatic irregularities. The result is a continuous colour, with balanced reflects and no artificial contrast. Indicated for correcting 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 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% natural origin ingredients, this coloration offers professional performance with a gentler approach. Suitable for colour maintenance, reflect correction and shine enhancement for dark blonde hair.

You can use any Diactivateur developer with Dia Color (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 min development time starts at the end of the application.
Root retouch: Apply to the root area, start the 20 min development time and 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 min, if the 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.
