I bought today the Refectocil color to my almost black eyebrows, adjust my bright red hair. The beiligende instructions I have exactly followed (2cm color 25 drop-Oxidant Creme) and at first I was just lumps. But if the mixture is stirred for a while and the product is left to stand, the whole is creamier and easier to apply. The paint smell relatively strong and burning something, but that's quite similar with hair color. After applying the paint was easily removed and the result pleased me well - even very slightly blotchy, But you can touch up and is determined with the time / exercise :) even better. I'm going to use the product in the future.
little tip: You should really stir long, preferably with a brush, and apply it with this.
