Hi, I was wondering if anyone can help me by advising how I can achieve going from very dark brown (base 4) to a red colour without using bleach. I was thinking maybe L'Oreal Hi - Lights in magenta but I don't want it to be to brighter red, more like a dull slightly washed out looking red and also in not familiar with L'Oreal colour products as I use wella. Any help or advice would be much appreciated.
