Since it has become difficult in recent years to find Kupferrottönen good colorants for the purposes of long shelf life and I'm always on the lookout and try out all new products, I can say that this product is one of the better. Of course, even here in durability even place up - particularly with the gray hair! - But compared to other products in which the success in this respect often after 2 weeks is then cuts this means but from better. The color is also beautiful, even if it always with me first of all a bit darker than it should fail on the package according to representation. What bothers me is that, but not very, and it will then also brighter, after a few times washing hair. About the smell, handling, etc., there is nothing special to say. Works in a conventional way and you have to specifically note anything. But I'm of course already an old hand ;-) The only drawback: the hue of copper you get in most stores do not, so you have time to reorder online!
