Demi-permanent light blonde colour with cool reflection, ammonia-free for neutralisation and gloss shine

The L’Oréal Pro Dia Color Demipermanent Colour 8.1 is a tone-on-tone, ammonia-free colour, designed to work on light blonde bases with a balanced cool direction. Shade 8.1 is positioned as a light blonde with a cool reflection, ideal for controlling warm tones and maintaining a natural result with greater chromatic precision.

When applied to dry hair, the creamy texture uniformly coats the hair fibre, allowing for precise and controlled distribution. The colour develops progressively, revealing a light blonde with a cool nuance and visible gloss shine. The hair appears more uniform, with visual lightness and a polished finish from roots to ends.

The lost melanin replacement technology acts within the hair fibre, replicating the natural colour and filling chromatic irregularities. The result is continuous colour, with balanced reflections and no artificial contrast. Indicated for neutralising unwanted warm tones, 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 guarantees greater comfort during the service and respect for the hair fibre.

With up to 92% natural-origin ingredients, this colour offers professional performance with a gentler approach. Suitable for colour maintenance, tone correction, and shine enhancement in light 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.

Wear suitable 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 processing time begins at the end of the application.
Root touch-up: Apply to the root area, begin the 20-min processing 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 lengths and ends are moderately faded.
Emulsify during the last 5 min if the colour is slightly faded.
At the end of the exposure time, emulsify carefully for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
