Learn how to prevent brassiness, choose the right toning products, and maintain vibrant blonde hair with expert tips and product recommendations.
Quick answer
To keep blonde hair bright and brass-free, use a purple toning shampoo like KEEP MY COLOUR BLONDE SHAMPOO once or twice a week, and follow with a blue-based treatment like KEEP MY COLOUR TREATMENT BLONDE to neutralize warm tones and boost shine. Consistent use prevents brassiness and maintains cool, vibrant blonde.

Blonde hair is stunning, but it comes with a unique challenge: brassiness. That unwanted yellow or orange tint can dull your color and make it look less vibrant. Whether you're naturally blonde, highlighted, or balayaged, fighting brass is a constant battle. The good news? With the right hair care routine and products, you can keep your blonde looking fresh and cool-toned between salon visits.
In this guide, we'll explore why brassiness happens, how to prevent it, and the best products to incorporate into your routine. From purple shampoos to blue toners, we'll cover everything you need to know to maintain that iconic Aussie blonde.
Why Does Blonde Hair Turn Brassy?
Brassiness occurs when the underlying warm pigments in your hair become visible as your color fades. This is especially common in blonde hair because the lightening process removes natural pigment, leaving hair more porous and susceptible to environmental factors like hard water, sun exposure, and heat styling. Over time, these factors cause the color to oxidize, resulting in yellow or orange tones.
The best way to combat brassiness is through regular toning. Toning products use color theory to neutralize unwanted warm tones. Purple shampoos and conditioners counteract yellow, while blue-based products are effective against orange. Incorporating a toning shampoo into your weekly routine can help maintain a cool, bright blonde.
- Use lukewarm water when washing to prevent color stripping.
- Limit heat styling and always use a heat protectant.
- Rinse with cool water at the end of your shower to seal the cuticle and boost shine.
The Role of Purple and Blue Shampoos
Purple shampoo is a staple in blonde hair care. It contains violet pigments that neutralize yellow tones, keeping your blonde looking cool and bright. However, not all purple shampoos are created equal. Some can be drying or leave a purple tint if left on too long. It's important to choose a formula that is gentle yet effective.
For those with more orange or brassy tones, a blue-based shampoo or treatment may be more suitable. Blue neutralizes orange, making it ideal for darker blondes or those with a warmer base. Products like KEEP MY COLOUR TREATMENT BLONDE use a blue base to reduce brassiness while adding shine and conditioning benefits.
- Start with once a week and adjust based on your hair's needs.
- Leave the shampoo on for 2-3 minutes for best results.
- Alternate with a moisturizing shampoo to prevent dryness.
Building a Brass-Free Hair Care Routine
A consistent routine is key to maintaining vibrant blonde hair. Start with a sulfate-free shampoo to avoid stripping color. Incorporate a toning shampoo once or twice a week, and follow with a nourishing conditioner. Weekly treatments can also help keep your hair healthy and shiny.
When choosing products, look for ingredients that strengthen and hydrate. For example, KEEP MY COLOUR BLONDE SHAMPOO contains soy proteins and natural extracts that strengthen hair and add volume while boosting blonde tones. Pair it with a treatment like KEEP MY COLOUR TREATMENT BLONDE to enhance shine and condition with Macadamia Seed Oil.
- Wash your hair less frequently to preserve color.
- Use a deep conditioning mask weekly to keep hair hydrated.
- Protect your hair from the sun with a UV-protectant spray.
Diagnosing Your Brassiness
- Symptom: Your blonde hair looks yellow or orange, especially in natural light. This indicates a buildup of warm tones that need neutralizing.
- Likely cause: Fading color, hard water minerals, or heat damage have exposed underlying warm pigments. Adjust your routine to include toning products and protective measures.
- Corrective action: Incorporate a purple or blue toning shampoo and treatment into your weekly routine. Use as directed to avoid over-toning. Start with once a week and monitor results.
- Stop or choose another option: If you notice excessive dryness or a purple/blue tint, reduce frequency or switch to a more moisturizing formula. If brassiness persists, consult your stylist. Your hair's health is a priority; adjust as needed.
