Wella Professional Koleston Perfect Me™+ Pure Naturals - Permanent Hair Color

Wella Professional Koleston Perfect ME+ Permanent Hair Color in shade 9/01 delivers precise lightening and consistent neutral-ash deposition for stylists and color formulators seeking reliable gray coverage without ammonia exposure.

Targeted Cool Blonde Formulation

The 9/01 designation represents the lightest blonde level fortified with neutral and cool pigments to counteract yellow or brassy undertones during the coloring process. This 60 ml tube utilizes the proprietary ME+ system, which eliminates ammonia in favor of alternative alkalizing agents and naturally derived colorants to reduce scalp irritation while preserving hair elasticity. The permanent pigment matrix penetrates the cortex to create long-lasting hold that resists fading between professional appointments.

Application & Mixing Behavior

• Suspends evenly in solution when blended with standard hydrogen peroxide developers for customizable lift and deposit intensity
• Cream-based consistency ensures uniform distribution across resistant regrowth, previously colored sections, or mid-length refinements
• Standard 60 ml packaging supports precise volume measurement for single-service salon formulations

Color specialists apply 9/01 when working with warm underlying pigments that require immediate cooling, or as a standalone permanent service for clients pursuing ash-blond results with complete gray coverage. The formula’s controlled oxidation rate allows stylists to mix batch quantities at the bowl without rapid degradation, ensuring smooth application from roots to ends while maintaining consistent density across varying hair porosities.
