GOODBYE YELLOW® is a hair care solution designed for clients seeking to maintain cool blonde tones. This product neutralizes unwanted yellow undertones, prevents color fading, and enhances color intensity. Formulated with a calibrated combination of purple and blue direct dyes, it gently cleanses the hair while counteracting cool tone color fade.

For in-salon service, apply as a shampoo on wet hair, leave for up to 5 minutes depending on the technique, and then thoroughly rinse. The color result and longevity vary based on hair condition and processing time. Professional gloves are recommended during application to prevent staining, and development time may be slightly increased on non-porous hair for intensified results.

For home maintenance, use the product daily for maximum tonal deposit or 1-2 times per week for tonal maintenance.

GOODBYE YELLOW® Neutralizing Bonding Wash is sulfate-free, making it gentle on the hair and scalp. The ideal development time is up to 5 minutes on dry hair for optimal neutralization. The pH level of the wash is 4.5, and gloves are recommended during application to avoid staining. It can be used daily for increased pigment deposit and result strengthening, alternating with regular shampoo to maintain even color.
