Ammonia-free natural medium blonde demi-permanent hair colour for gloss shine and uniform colour
The L’Oréal Pro Dia Color Demi-Permanent Hair Colour 7 is a tone-on-tone, ammonia-free hair colour, designed to work on medium blonde bases for a natural, luminous, and balanced result. Shade 7 is a natural medium blonde, ideal for maintaining colour clarity while enhancing the hair's shine and uniformity.
When applied to dry hair, the creamy texture uniformly envelops the hair fibre, allowing for precise and controlled distribution. The colour develops progressively, creating a medium blonde with a visible gloss effect. Hair appears visually lighter, with immediate shine and a well-cared-for finish from root to tip.
The lost melanin replenishment technology acts within the hair fibre, replicating the hair's natural colour and filling chromatic irregularities. The result is a continuous colour, faithful to the base shade, without artificial contrast. Suitable for revitalising dull hair, evening out lengths, or softening the appearance of white 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 guarantees 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. Suitable for colour maintenance, first-time colouring, or enhancing shine on natural 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 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 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 min development time starts at the end of the application.
Root touch-up: Apply to the root area, start the 20 min 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 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, emulsify carefully for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
