Hi I'm not even sure if I'm allowed to post stuff like this ?!? My hair is white (and then dyed to make it dark blonde ) my white roots have arrived again , usually buy L'Oréal majirel 8.03 but this was getting Brassy so I switched to majirel 8.2 .... now I have pink / purple roots 
. Does anyone know what I can do to rectify ? Thanks
