Hi everyone. I just want to ask a question re Loreal Hi Richesse colours. At the moment I'm a 3 in Majirel (almost black.) I want to lift my hair colour about 2 levels, to a 4.15 with the Hi Richesse. Is this possible? I've used it already but as expected it took at the roots but not anywhere else. My question is: do you really need to use it with the specific releaser, or could I use it with a 6% peroxide? Thank you!
