Hi I have just done a skin test on a new client I am colouring and re styling next week. Her existing colour is a level 10 with an inch regrowth. She has 60% grey at the front going darker on her roots at the back. So I am wanting an ash blonde and was going to use Wella 10/16 with some 10/0. Would you suggest 6%. Her natural level towards the back is around a 6. Also she is wanting some slices of copper and brown through the front. Would you prepig on a level 10 and any suggestions on colour choice. Hope this makes sense. Thanks in advance
