I got true magenta hair with this dye. I was worried it wouldn’t work on my dark brown coloured hair but it did magic! I used 30 volume L’Oréal professional developer with it but left it on longer than the recommended 35 minutes. I couldn’t tell whether it was working when the dye was on my hair but when I washed it off I was amazed. My hair does look dryer now but it was already damaged before from all the bleaching I did in the past year. I washed my hair once so far since dying and the water was running red and it looks like the colour faded slightly or turned more red than magenta but it’s still a beautiful colour.
I've been using this colour for a.long time so it's good , in the picture I have got a tiny bit of purple at the ends ,ignore that the rest is the magneta
