What it is:
Goodbye Yellow is much more intense than a regular pigmented shampoo, so processing time is key to achieve desired results. Depending on 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 undertones, please wash the hair with BC Bonacure Deep Cleansing Shampoo at the shampoo bowl.
- *Please note that the performance of Goodbye Yellow depends on hair conditioner. The more hair is stressed, the more intense is the nenutralizing effect.
