But, how do you know what shade of blonde toner to use? Start by looking at the underlying pigment the lightener has exposed. If the hair hasn’t yet been lightened, preempt the tone that might appear as a result of lifting. As for ratios, we recommend mixing the colour 1:1. For example, you might try 30g Koleston Perfect or Illumina color + 30g Welloxon Perfect Developer. Koleston Perfect is always mixed with Welloxon Perfect to achieve outstanding colour results. After Treatment: using PH optimizes care products will enable better colour retention. The perfect partners for Koleston Perfect is INVIGO brilliant shampoo and INVIGO Post colour treatment. Warnings

Combine Koleston Perfect Deep Browns hair colour with Welloxon Perfect for outstanding results. Simple 1:1 mixing ratio. Apply the hair colouring mixture immediately with your chosen technique. We cannot guarantee accurate results with the use of any other developers. Regimen indications
