Schwarzkopf Goodbye Yellow Shampoo, 10.1 oz

What it is: Goodbye yellow is much more intense than a regular pigmented shampoo, so processing time is key to achieving the desired results. Depending on the hair base and conditioner, an over-processing time of the color can result into a greenish/blueish color undertone. What else you need to know: To remove this unwanted undertone, please wash the hair with BC bona cure deep cleansing shampoo in the shampoo bowl. Please note that the performance of goodbye yellow depends on the hair conditioner. The more hair is stressed, the more intense the neutralizing effect.
