L´Oreal Professionnel Diactivateur 9vol 2 7% 1000ml

L’Oréal Professionnel Dia Activateur II delivers controlled oxidation for professional color and lightening services through a precisely calibrated 9-volume developer.

Precision Formulation for Dia Systems

This 2.7% active peroxide solution is specifically engineered to combine with L’Oréal Dia color and Dia lightening emulsions. The 1000 ml bulk packaging maintains chemical stability across multiple service rotations, supporting high-volume salon workflows without compromising consistency between batches.

Targeted Application Protocols

• Maintenance root retouches requiring gradual lift
• Gloss, mask-tones, and demipermanent deposits with minimal processing power
• Delicate lightening on previously processed mid-lengths and ends
• Color correction windows where extended processing control prevents over-development

The reduced oxidation rate slows the reaction curve, allowing colorists longer working time to achieve even melanin extraction and accurate pigment saturation. This approach reduces cuticle stress and helps preserve the hair cortex’s structural bonds during routine servicing. Designed exclusively for licensed practitioners, the activator requires standard dilution ratios and adherence to professional safety protocols when paired with Dia series pigments.
