Had my hair from golden blonde to reddish tinted honey blonde ... in believing that the red pigments would be sufficient. Actually, the grünstich inevitable when natural. Hab then first serviced if it is after a couple of washes better. It was honestly only under certain light as a glimmer. Took me but more reminiscent of moss. Well ..grün must be neutralized with red so I found the sound perfect ... not too much copper but adequate ... and tatataaaaa it has become really beautiful. Smells totally enjoyable and my hair has not broken, as it was before already: D So I can really recommend it in such a case!
