Demi-permanent hair colour, very light blonde with a balanced cool golden reflect, ammonia-free for gloss shine and luminous colour
The L’Oréal Pro Dia Color Demipermanent Hair Colour 9.13 is a tone-on-tone, ammonia-free colour designed for very light blonde bases with a balanced cool and luminous direction. The 9.13 shade is positioned as a very light blonde with a cool reflect softened by a golden nuance, ideal for refining colour, controlling excessive reflects, and maintaining a natural, elegant finish.
When applied to dry hair, the creamy texture evenly coats the hair fibre, allowing for precise and controlled distribution. The colour develops progressively, revealing a balanced very light blonde with a visible gloss shine and a more stable chromatic reading. Hair appears more uniform, with visual lightness and a polished finish from roots to ends.
The lost melanin replenishment technology acts inside 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 excessive warm reflects, softening unwanted tones, or evening out faded lengths.
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. Suitable for colour maintenance, reflect correction, and shine enhancement in very 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 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-minute development time begins at the end of the application.
Root touch-up: Apply to the root 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 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, carefully emulsify for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
