Product that works!

The Bad:

- Sent horrible, rotting between the egg and pet foireux
- It is rather long and laborious, especially in the rinse time.

Remarks:

- The product removes all color pigments in your hair to regain the lighter color. So try to remember what color is hidden under your coloring to avoid nasty surprises.
- You can start again Colour B4, 3 times, if the result is not convincing.
- It is said that you can recolor immediately after ColourB4
-As Said before, the worst that can happen is that it does not. The reasons may be that you have not rinsed long enough or the exposure time was not long enough. Or you have too many silicone products in your hair.

What I recommend is that the 2 shampoos foregoing ColourB4 you do with a purifying shampoo without moisturizing agents, the Head & Shoulders style and especially not after shampooing or care. Personally I used this shampoo HERE.

The verdict
I am very happy with the result, this saved me a hundred euros, if I had been to the hairdresser. My hair is not drier than before. The color is slightly lighter than my natural color (bits before) but it does not displease me. I had some yellow highlights that are easily faded with déjaunissant purple shampoo or conditioner.
