Transparent, pigment-free demi-permanent hair colour for gloss shine and colour customisation
L’Oréal Pro Dia Color Demi-Permanent Hair Colour Clear is a transparent, pigment-free base, designed to dilute shades, soften reflections, and enhance hair's shine without altering the tone level. It functions as a technical modulator within the Dia Color range, allowing professionals to adjust colour intensity or create a pure gloss service.
When applied to dry hair, the creamy texture distributes evenly, enveloping the hair fibre without adding colour. The result is immediate: a visible gloss effect, with increased shine, a soft touch, and a healthy appearance. The hair maintains its natural or previously coloured shade, but with a more luminous and uniform finish.
The lost melanin replenishment technology acts within the hair fibre, improving the visual quality of the colour and filling in chromatic irregularities. When mixed with other shades in the range, Clear allows for reducing reflection intensity, creating more translucent results, or adapting the colour to different technical needs.
With a duration of up to 6 weeks, the effect remains stable and luminous. The ammonia-free formula ensures greater comfort during the service and respects the hair fibre. With up to 92% naturally derived ingredients, it offers a versatile solution for shine, correction, and colour customisation services.

You can use any Diactivateur developer with Dia colour (mixing ratio: 1 + 1.5). For best results, we recommend: Diactivateur 6 vol. for gentle colour deposit; Diactivateur 9 vol. for medium colour deposit; Diactivateur 15 vol. for intense colour deposit.
Use appropriate disposable gloves. Do not use metal tools (bowl, comb...). Only use the recommended Diactivateur.
In a non-metallic bowl, applicator bottle, or shaker, mix 60 ml (1 tube) of Dia Color cream and add 90 ml of your 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, 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 processing time, emulsify carefully for a few minutes. Rinse hair thoroughly until the water runs clear. Wash with Metal Detox shampoo.
