I made a mistake coloring my hair and now have very brassy color (bleached dark blond hair). I can't afford a salon fix right now. I ordered a product called Red Gold Corrector Plus (Ardell brand). It comes in a 7 ml. bottle. It says to add to color or toner, or, add to shampoo. I want to add to my shampoo, but it does not say how much/ratio or how long to leave it on. I read stories on line about people leaving toner on too long and ending up with purple hair. Does anyone know how many drops of this stuff to add to how much shampoo and how long to leave it on for? How often to use it? The instructions don't say. Can someone please help me? Thanks.
