I had read a lot of articles on various blog and the product B4 Colours seemed perfect. I'm naturally blond with dark ashy reflection. My last color was dated five weeks, it was a dark golden blond ash professional version that is very dark !!. I had made a little disgorged. So I started with the color B4. There are so many parameters (color level, color quality, the frequency of coloring, how long we dyed his hair ...) must be taken into account that the results are completely different haired to another. For me it does not happen significantly. At first rinse my hair was almost orange, I was somewhat disturbed but after several minutes and rinse other, they had taken a dark golden blond hue and 24 hours after they have recovered their color with just a shade lighter. I used the Regular I was afraid to use the Extra. I think this is a product that works very well on very dark hair whose natural base is very clear. Small precision, colored hair never regains its original color, it is impossible. Once the natural pigment is replaced in the hair scales with an artificial pigment it does not return.
