The perfect partner for a perfect colour result. Wella Professionals Welloxon Perfect Developer 6% (None Vol) is the ideal developer for Wella's Koleston Perfect, Blondor and Illumina Color ranges.

This 6% (None Vol) strength is for 1-2 levels of lift and grey coverage, same depth or darker.

What it does

The developer (oxidant) is what activates permanent colour and lightener, and its strength (volume) sets how much lift you get. Welloxon Perfect is engineered to pair precisely with Wella's Koleston Perfect, Blondor and Illumina ranges for accurate, reliable, true-to-tone results. At 6% (None Vol), it delivers 1-2 levels of lift and grey coverage, same depth or darker. The smooth consistency makes mixing easy and even, and rinsing fast.

How to use it

For professional use, with an allergy alert test carried out on the colour at least 48 hours before use. Mix with your Wella colour or lightener at the ratio specified for that product, apply, process for the recommended time, then rinse. Choose the volume to match your desired lift.

Who it's for

This one's for colourists using Wella's Koleston Perfect, Blondor or Illumina colour who need the correct, precisely-matched developer. We've been perfecting colour, blow-dries and styling for clients in Codsall for years, and using the right developer at the right volume is fundamental to an accurate, reliable colour result.
