Have newly tinted blond hair that is too brassy ?? or highlights that have a brassy (yellow-ey) cast to them, how would you neutralize that?............go to the color wheel........where is yellow on the wheel ?? remember to neutralize or cancel it out, you go where?????
If your brass is really tough use the shampoo and conditioner made by either of the 2 companies OR I make one specific just for you its called "HINT"
