For Yellow or Orange-Toned Blonde Hair

Yellow tones typically show up in lighter blonde or platinum hair, appearing as a dull, brassy yellow cast, especially in natural light. Orange tones tend to appear in darker blonde, bronde, or previously brunette hair that's been lightened, showing up as warm, coppery undertones rather than yellow.

Purple or violet-based products cancel out yellow tones, since purple sits directly opposite yellow on the colour wheel. This is why purple shampoo and conditioner are the standard toning solution for light blonde and platinum hair.

Blue-based products cancel out orange tones, since blue sits opposite orange on the colour wheel. This is typically recommended for darker blonde, bronde, or brunette hair with warm undertones that purple alone won't fully neutralize.

Yes, some people with multi-tonal regrowth or blended colour use both, applying blue to more orange-toned sections (like roots) and purple to more yellow-toned lengths and ends. If you're unsure, starting with the product that matches your dominant tone is usually simplest.

Toning pigments gradually fade with each wash and don't permanently alter hair colour, so brassiness will return over time regardless of formula. Using your toning shampoo consistently, typically 1-2 times per week, helps maintain results between colour appointments.
