Why blonde hair turns yellow and how to stop it
Yellow and orange tones are normal in lightened hair. Where they come from and how to keep blonde clean.
Where the yellow comes from
When hair is lightened, natural pigment goes in stages: brown to red, red to orange, orange to yellow. Those warm undertones sit beneath any blonde. The toner applied at the end neutralises them, but it wears off with washing.
Sun, heat from straighteners and minerals in the water add to it. That’s why a cool blonde needs upkeep.
Toning at the salon
A gentle colour that puts back the shade you want, neutralises yellow and adds shine. At KULTURA we tone with gel colour; single-tone colour or toning costs ARS 128,000 to ARS 224,000 depending on length (November 2026).
Purple shampoo at home
Purple sits opposite yellow on the colour wheel, so it cancels it out. A purple shampoo such as BLONDME Purple (ARS 31,000) and its conditioner (ARS 34,000) help the tone last between visits. Use it once or twice a week, alternating with your usual shampoo: every wash can leave a lilac tint.
Repair as well as tone
Lightening weakens the hair. For blondes that need nourishment, Schwarzkopf Professional’s BLONDME Bond Repair Nourishing line (shampoo, conditioner and mask) looks after lightened hair; for very damaged hair, the Bondfinity Deep Repair mask.
Habits that help
- Warm, not hot, water.
- Heat protection before the dryer or straighteners.
- A hat in strong sun and a cap in the pool.
- Regular toning at the salon.
