I use otherwise always Sante Color Creme "Cognac Blonde", which I'm actually very pleased, however, the color effect is still relatively low, which is why I wanted to try to compare other herbal hair colors. Compared to the Sante product I find Logona Cream minimally worse händelbar because it is somewhat thinner, but also so that it can be handled easily, by smell and consistency here are the two products otherwise very similar (the Logona cream smells a little less intense by Orange). From the color effect is here with me the Logona Copper Blonde actually been somewhat stronger and long-lasting, but probably primarily by the copper values in Sante Cognac blonde you see less effect, but he likes better. As my slightly reddish tend naturally dark blonde hair anyway this is probably exacerbated by the LOGONA hair color. After a few weeks, especially the blush remains. Whether the color would be suitable to cover gray hair, I can not judge. Generally (for inexperienced) to say that let in natural hair colors make little generalizations for color result. My hair seems the natural hair color quite well to accept, although we must (at least for the blonde tones that indeed can not lighten) do not expect any significant changes to the natural hair color, usually it is the result will be a golden / reddish tinge to the hair. I use the color primarily about my dark blonde tone spice things up, what works well. When the exposure time, it is advisable to keep them quite long (I'll usually between 90 minutes and 2 hours to act).
