Demi-permanent very light blonde hair colour with a cool mocha reflect, ammonia-free for neutralisation and glossy shine

The L’Oréal Pro Dia Color Demi-Permanent Hair Colour 9.82 is a tone-on-tone, ammonia-free colour designed to work on very light blonde bases with a sophisticated cool direction. Shade 9.82 is positioned as a very light blonde with a cool mocha reflect, ideal for controlling warm reflects and creating a more elegant and uniform finish.

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 very light blonde with a cool nuance and visible glossy shine. Hair appears more uniform, with visual lightness and a polished finish from root to tip.

The lost melanin replenishment technology acts within the hair fibre, replicating natural colour and filling chromatic irregularities. The result is continuous colour, with balanced reflects and no artificial contrast. It is suitable for neutralising 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 white 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 hair colour offers professional performance with a gentler approach. It is suitable for colour maintenance, reflect correction, and shine enhancement on very 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 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, etc.). Only use the recommended Diactivateur.
In a bowl, applicator bottle, or shaker, mix 60ml (1 tube) of Dia Color cream and add 90ml of the 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 root area, begin the 20-minute development 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 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, emulsify carefully for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
