How Do You Neutralise Brassy Tones?
The short answer
Neutralise brass with the tone directly opposite the unwanted colour: violet for yellow, blue for orange, and blue-green for a strong orange-red. Mix it as a toner rather than a permanent colour when the level is already correct, and expect to re-tone every four to six weeks as the undertone resurfaces.

| Orange | Level 6 to 7 lift | Blue or blue-ash toner |
| Orange-red | Level 4 to 5 lift | Blue-green or teal toner |
Why brass keeps coming back
Toner sits on the surface of the cuticle and washes out before the underlying warmth leaves. Brass returning is normal, not a sign the original application failed.
The way to slow it is to reduce exposure: cooler water, a violet or blue maintenance wash once or twice a week, and less heat styling on the lightened sections.
Frequently asked
How often should a blonde be toned?
Every four to six weeks for most clients. Stretching past eight weeks usually means the toner has already gone and the brass is showing.
Can I pre-tone before lightening?
Pre-toning is a colour correction technique rather than routine maintenance. For standard maintenance, tone after the lift.
