Permanent: Yes. Green: a little.

To test, we took a few strands (last browning was a while ago, so that a 5 cm approach was there), one week, bleached really bright before the green color. I then have taken a week brighteners as flushing, who has taken the yellowness of the hair almost completely out; 5 cm from neck were almost white, including, where even the brown coloring was drinne, they were blond.
Green came over it then, stinks a bit, but what color does it mean? After washing: Wow! Green! Brilliant! After the first wash your hair, was the Anastz (the 5 cm!) Blue! Properly bright bright blue! danrunter they were turquoise and including moss green, darker than in the picture in the article description! I thought this looked still great, got me so not angry or so and I wüde the color definitely order again, because they (whether now green, or blue) keeps really long, with time a little brighter, but that does me neither.
In any case, you should be clear about the fact that this color can be blue 1. and 2. that it attacks the hair massively! Even with irrigation and care sprays it's really not hard!
Then times have fun surprise dyeing! Let's see what happens with me the next time you try! Will test even the purple, maybe wirds Pink!
