Demi-permanent light blonde hair colour with an iridescent reflect, ammonia-free for neutralisation and gloss shine
The L’Oréal Pro Dia Color Demi-permanent Hair Colour 8.2 is a tone-on-tone, ammonia-free hair colour, designed for light blonde bases with a subtle cool direction. The shade 8.2 is a light blonde with an iridescent reflect, ideal for softening warm undertones and creating a more refined and even finish.
When applied to dry hair, the creamy texture uniformly coats the hair fibre, allowing for precise and controlled distribution. The colour progressively develops, revealing a light blonde with a cool nuance and visible gloss 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. Suitable for neutralising unwanted warm undertones, 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 respects the hair fibre.
With up to 92% natural-origin ingredients, this hair colour offers professional performance with a gentler approach. Suitable for colour maintenance, tone correction, and shine enhancement in light 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 appropriate disposable gloves. Do not use metallic 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 the chosen Diactivateur developer. Apply to dry hair.
First application: The 20-minute development time starts at the end of the application.
Regrowth touch-up: Apply to the regrowth area, start 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 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 development time, carefully emulsify for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
