Blonde, highlighted, balayage, or grey/white hair — whether achieved through salon lightening or natural — that's developing yellow or brassy undertones between colour appointments.

Suitable for both professional maintenance between salon toning services and informed home use, but not intended as an everyday shampoo for hair that isn't lightened, since the violet/blue toning dyes serve no purpose on darker or unlightened hair.

The value of this shampoo isn't a vague anti-yellow claim — it's that the correction is done with actual violet/blue direct dyes that neutralize warm tones the same way a salon toner does, just delivered in a rinse-out wash step, which is why it's positioned as maintenance between glossing services rather than a replacement for them.

Work through wet hair, lather, and rinse thoroughly. Goldwell does not publish a specific recommended dwell/leave-in time for this shampoo, so it should be used as a standard rinse-out wash rather than left on for extended toning.

Pros

• Delivers colour correction through actual violet/blue direct dyes rather than a vague 'purple shampoo' marketing claim, so the toning mechanism is verifiable from the ingredient list itself.
• Polyquaternium-10 and Panthenol are included specifically to counter the dryness that dye-based toning shampoos commonly cause on already-lightened hair.
• A milder sarcosinate/sultaine surfactant blend is used alongside sulfates rather than a harsher sulfate-only wash.

Cons

• Still contains Sodium Laureth Sulfate and Isopropyl Alcohol, both of which can compound dryness on porous, over-lightened hair if used at every wash.
• Because it works via violet/blue direct dyes, overuse or extended contact time can leave a faint ashy or violet cast on very pale platinum or white hair.
• Contains added fragrance and a synthetic optical brightener, ingredients some sensitive-scalp users choose to avoid.
