Hi i am currently training and something just doesnt sit with me.
At college we use wella and when toning hair we use colour touch and the pastel developer. My question is if needing to tone with lets say a 9/18 can i use a 3% 10vol or a 6%20vol. Would the 6%20vol lift any brassy tones that needed lifting and would the 3% 10vol just deposit lighten/darken 1 shade when toning
