Use the shampoo at the wash station as a convenient toning product, but remember to recommend it for home care to maintain blonde hair between salon visits. Product Development Coordinator Sara Kumpulainen explains what happens to hair during the lightening process and why yellow pigments emerge.

What Causes Yellowing?

- Impurities in water
- Heat styling
How Does Professional No Yellow Shampoo Work?
Hair color is formed by two main pigments: eumelanin, which is black-brown, and pheomelanin, which is red-yellow.
When hair is lightened, bleaching agents oxidize and break down the melanin pigments in the hair. Sunlight’s UV rays also break down melanin in hair, similar to a chemical lightening process.
The reason for yellow tones in hair is actually quite simple: “Eumelanin generally breaks down more easily and quickly than pheomelanin, which is why hair first turns orange and then yellow during the lightening process,” Sara explains.
Hair Lightening Is a Yellow Process
When hair is lightened, the ideal blonde base is always considered. The ideal lightening base for hair levels 9–10 is yellow or pale yellow. After lightening, hair is often toned to neutralize yellow tones and enhance the desired color.
Sara also explains why lightened hair fades more easily: “Lightened hair is often porous, and the tone does not last as long as in healthy hair. Additionally, the amount of pigment used in blonde hair is always smaller than in darker hair because the goal is to avoid darkening the hair too much.”
“Lightened hair is often porous, and the tone does not last as long as in healthy hair.”
The answer to neutralizing yellow tones lies in complementary colors: “The opposite color of yellow is violet, meaning they cancel each other out. When blonde or gray hair needs to stay cool-toned, violet pigments are used to neutralize yellow shades,” Sara explains.
