Wella Professional Koleston Perfect Me™ Rich Naturals - Permanent Hair Color

The Wella Professional Koleston Perfect Me™ Rich Naturals hair color in shade 7/18 delivers a controlled medium blonde ash pearl finish while providing durable permanent coverage through a precise professional formulation.

Targeted Ash Correction for Level 7 Substrates

Designed for salon environments and trained colorists, this permanent dye formula addresses unwanted warmth in medium blonde foundations. The 7/18 classification registers as a cool-toned level 7, neutralizing residual gold and copper reflections while depositing subtle pearl clarity. Matching this exact specification prevents overly dark or muddy transformations often caused by mismatched ash toners.

Each unit ships in a standardized 60ml measurement tube, engineered to yield consistent single-service volume when combined with a compatible professional oxidant. This fixed capacity removes estimation errors during formulation and ensures accurate pigment-to-liquid ratios across every treatment.

• Cosmetic Result: Permanent oxidative system anchors cool, medium-blonde pigments deep within the hair shaft for fade-resistant, reflective ash finishes.
• Application Scope: Suitable for full-head gray coverage, root refreshment, or warming-tone correction on virgin and previously colored hair.
• Inventory Efficiency: The 60ml packaging supports routine replenishment cycles while minimizing waste between scheduled coloring appointments.

Selecting 7/18 requires evaluating the existing hair depth and porosity to guarantee accurate ash manifestation. Follow established professional mixing parameters and perform strand testing prior to complete application. Maintain the sealed container in a stable, cool environment to preserve pigment suspension until ready for use.
