Demi-permanent dark blonde colour with copper red reflect, ammonia-free for glossy shine and vibrant colour

The L’Oréal Pro Dia Color Demi-permanent Colour 6.45 is a tone-on-tone, ammonia-free colour, designed for dark blonde bases with a warm and expressive tone. Shade 6.45 is a dark blonde with a copper red reflect, ideal for intensifying colour, warming the hair, and creating a more vibrant finish without compromising on natural look.

When applied to dry hair, the creamy texture evenly coats the hair fibre, allowing for precise and controlled distribution. The colour develops progressively, revealing a visible dark blonde with copper red reflect and immediate glossy shine. Hair appears more luminous, with depth and a more striking finish from root to tip.

The lost melanin replacement technology works within the hair fibre, replicating natural colour and filling chromatic irregularities. The result is continuous colour, with tone-true reflects and no artificial effect. Suitable for revitalizing dull hair, intensifying warm reflects, or 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 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, enriching reflects, and boosting shine in 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 suitable disposable gloves. Do not use metal utensils (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 processing time begins at the end of application.
Root retouch: Apply to the root area, begin the 20 min processing time, then immediately distribute through the rest of the hair to revitalize 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, carefully emulsify for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
