Removing BRIGHT red hair.?

Oh dear this is tricky , i would say wash your hair LOTS with washing up liquid it is strong so will remove some red as a result it will go lighter red / orange Lighter due to the fact bleach originally stripped your hair .......then consider toning down with semi-permanent color Wouldn't use black possibley med / dark brown best advise go to a salon ....... Expensive but safe your hair your crown and glory :-)
