I ordered this from Amazon but unfortunately there are no instructions in English. I've looked on Youtube but still unsure how to use it. Has anybody used it and do you need to mix it with some Emulsion which was mentioned on Youtube. I'm new to all this. I do have Wella color fresh mask caramel glaze which I use every 10 days or so but that's just apply for 10 minutes, rinse and renew when needed. Thought Color Touch might last a little longer. Also if you have used it could you tell me if I have to use the whole tube and how long I should leave it on for.
Thanks for your help.
