How to Use (Quick Guide)
Mix L'Oreal Dia Color with Dia Activateur Developer in a 1:1.5 ratio. Choose developer strength based on desired results: 6-vol. for subtle tone-on-tone deposit, 9-vol. for standard maintenance colouring, or 15-vol. for stronger colour payoff and grey blending. Apply to mid-lengths and ends first, then to roots in the final minutes. Process according to the specific shade and developer used, then rinse thoroughly with cool water and finish with conditioner.
