I bought these> color in the barber shop, but here then again ordered because the color is here cheaper. Since I myself have natural red hair, I was not sure how the color result is. The hairdresser said that color is bad or not at all come out. Result is that I beautiful, have purple tips, in a beautiful violet tone. I have the color it left 45 minutes and then rinsed. Hair still silky and shiny, were wonderfully scour thereafter. The fact that was omitted on ammonia etc, the color is not harmful for the hair and it does not stink beiweitem. In the shower no purple spots were after rinsing to be found, as I had it, for example with red. From the clothes went to a clothes from towels and shirt stains immediately back out.
The only drawback is that the color does not hold very long, in some places my normal hair color comes through (after less than a week :() and the tips are already blue again. This is a minus point for me, but you can overlook that, in the color result.
