I am a former colorist at Star Colorist at L'Oréal, I was blonde for 20 years and the radical change in salon, we are no longer a professional color, but now with this shade, after a super oxidized bleached blonde, it is the only formula that covers my white hair for 20 years and completely covered my blond hair with no green reflection, obviously I had to turn my color up with red but delighted to have discovered Excellence from L'Oréal.. I recommend this formula.
