Medium blonde demipermanent hair colour with a cool reflect, ammonia-free for neutralisation and gloss shine
The L’Oréal Pro Dia Color Demipermanent Hair Colour 7.1 is a tone-on-tone, ammonia-free hair colour, designed to work on medium blonde bases with a cool and controlled direction. Shade 7.1 is positioned as a medium blonde with a cool reflect, ideal for neutralising warm reflects and creating a more balanced and natural 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 medium blonde with a cool nuance and visible gloss shine. The hair appears more uniform, with visual lightness and a carefully maintained 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. Indicated 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 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% naturally-derived ingredients, this hair colour offers professional performance with a gentler approach. Suitable for colour maintenance, reflect correction, and shine enhancement in medium 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 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...). 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 processing time begins at the end of the application.
Root retouch: Apply to the root area, start the 20 min processing time, and 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 water runs clear. Wash with Metal Detox shampoo.
