Why Does Blonde Hair Turn Brassy? Causes & How to Fix It
Blonde hair can look fresh and bright straight after a salon visit — but over time, it can start to develop unwanted yellow or orange tones.
Here’s why that happens, and what you can do to keep your colour looking its best.
What causes brassiness?
Brassy tones appear when warm pigments become visible in the hair. This can happen for a few reasons:
Natural underlying tones in your hair
Sun exposure
Hard water
Heat styling
Product build-up
Even the best colour will need maintenance over time.
How to prevent blonde hair going brassy
A few simple changes can make a big difference:
Use a purple shampoo once or twice a week
Avoid over-washing your hair
Rinse hair after swimming (chlorine can affect tone)
Use heat protection when styling
Consistency is key — small habits help maintain colour for longer.
When to book a toner
If your blonde is starting to look dull or warm, a toner can quickly refresh the colour.
This is a quick salon service that helps neutralise unwanted tones and restore brightness without a full recolour.
Keep your hair in good condition
Healthy hair holds colour better.
Regular conditioning treatments — both at home and in the salon — help keep your blonde looking smooth, shiny and vibrant.
