L´Oreal Professionnel Diactivateur 15vol 4 5%

A 15 volume (4.5%) professional oxidant designed to activate permanent and demi-permanent color formulations with steady, controlled lift and predictable pigment release.

Precise Oxidation & Consistency

Rated at 4.5% hydrogen peroxide concentration, this diactivateur supports gentle lightening, extends color fade resistance, and refreshes muted tones while maintaining a stable cream viscosity. The thickened base prevents suspension separation during mixing, allowing accurate scaling ratios and uniform strand-to-strand application without dripping or uneven saturation.

Salon-Grade Packaging & Compatibility

Bearing the Dia Activateur II designation, this formula is calibrated for L’Oréal Professionnel color matrices and integrates reliably with standard professional neutral-ph chemistry. Packaged in a durable 1000 ml container, it accommodates high-frequency appointment schedules while preserving peroxide stability until the moment of tinting.

Core Specifications

• Active strength: 15 vol / 4.5%
• Physical state: Cream-based developer for precise measuring and even distribution
• Unit size: 1000 ml professional canister optimized for studio throughput

Blend with your chosen tinter using the specified ratio, saturate thoroughly from mid-lengths to ends, then rinse with cool water once optimal lift is achieved. Secure the container lid tightly after each use and store upright in a shaded, temperature-neutral area to prevent premature peroxide degradation.
