GOODBYE YELLOW is Schwarzkopf Professional's first highly-pigmented, anti-yellow wash. Free of SLS/SLES sulfates, this wash provides a gentle cleansing action and instant tonal deposit to counteract and neutralise underlying warm tones. The unique pigment combination of purple and blue direct dyes is formulated to neutralise unwanted yellow undertones, whilst gently cleansing the hair. The formulation is adjusted to a pH level of 4.5 for effective and long-lasting results. A combination of colour deposits and active washing substances allows for neutralising, cleansing and care in one simple step.
