Hi, So i did my client's roots with Wella 12/1 today, she's had it before and it worked well, but last time (at another salon) it went quite ginger. We weren't sure if maybe they used a cheap peroxide, or less than 12% so we decided to give it a go. She is adamant she doesn't want bleach, so it was this or a 12/11 or maybe 12/81 or 89. We tried the 12/1, it seemed to be coming along quite well in the first half hour but then seemed to stop developing. After an hour i got one of my senior colleagues to have a look because it was still bright orange, you could see it glowing through the mixture. She suggested the colour seemed to have dried out a lot and i should add some fresh for another 10 mins. This immediately lifted much better and the resulting colour, while still a bit warm, was pretty good. The condition wasn't so brilliant after being left so long though :irked: I'm still pretty inexperienced with colour and want to learn any tips i can to help in this kind of situation. Should i have added more colour halfway through? The girl's hair was very thick and she was under heat, does it stop working if it dries out too much? Want to do better next time! Thanks, Sky
