Use only when professional-level lift is required; for everyday colour services, opt for Wella Welloxon Perfect 6% or 9%. How to use Always read the Wella Color formulation guide and carry out a strand test 48 hours before service. Mix Wella permanent colour or bleaching agent with Welloxon Perfect 12% in the ratio specified by the colour line. Apply the mixture quickly and evenly to clean, dry hair using a tint brush. Process for the manufacturer-stated time (typically 30–35 minutes for high-lift services), checking development visually every 5 minutes. Rinse thoroughly and follow with a Wella post-colour treatment such as Wella Color Service Mask. Wear gloves throughout and dispose of unused mixture; do not store mixed product.
