Luckily, there are FAN Silver White, which was recommended to me by a friend of my yellowish hair warmly.
So I went to the user guide in and gave two fingers hat with the purple liquid that I had shaken hard, in a pint of water, thereby rinsing my hair. Did the whole procedure done in the sink (Note: The inevitable purple splatter stain the towels quite intense) while repeatedly doused my hair with the conditioner or hair immersed in it.
The result convinced: While the yellowness is still present, but become much more discreet. So I'm socially acceptable again and feel a lot better.
