The essential partner to your Dia colour. Dia Activateur 6 Vol by L'Oréal Professionnel is the crème peroxide activator and developer designed to be mixed with the Dia Light and Dia Richesse demi-permanent colour ranges. At 6 Volume, it's the gentle-strength developer that gives these demi colours their glossy, true-to-tone deposit-only result.

What it does for your hair

The developer (activator) is what makes hair colour work, and matching the right one at the right strength to your colour is essential for a predictable result. This 6 Volume crème activator is formulated specifically for the Dia demi-permanent ranges, at this gentle strength it activates the colour to deposit tone and add gloss without lifting the natural hair, which is exactly what gives Dia its glossy, refreshing, grey-blending finish. The crème consistency keeps the mixed colour smooth and workable for even, controlled application, so your colour goes on cleanly and develops consistently.
