Colour Correction Fix Brassy Hair

If you’re here because your hair doesn’t look the way you hoped it would - take a breath.

Maybe the blonde is too brassy.
Maybe it’s darker than you asked for.
Maybe there are stripes, bands, patches, or that heavy, flat tone that just doesn’t feel like you.

Or maybe the box dye seemed like a good idea at the time.

You’re not the first person to sit in this position - and you won’t be judged for it.

At Los Pastel in Subiaco, colour correction is handled with honesty, calm, and a clear plan. The goal isn’t to rush in and “fix” everything in one dramatic session. The goal is to move your hair forward safely and strategically, so you end up with the beautiful results you wanted.

What is Colour Correction?

Colour correction isn’t about panic solutions.

It’s about understanding what’s sitting in your hair and how it will respond. If your hair isn’t sitting the way it should - whether it’s brassy, dark, uneven, or just not you - a consultation is the first step.

You don’t need to know exactly what to ask for. That’s our job.

Book your colour correction consultation at Los Pastel Hair in Subiaco, Perth, and let’s create a clear plan to move your colour forward.


  • Colour correction isn’t about panic solutions. It’s about understanding what’s sitting in your hair and how it will respond.

    It can involve:

    • Softening heavy, block colour

    • Blending patchy or uneven balayage

    • Removing excessive warmth, brassiness, or flat ash tones

    • Lightening previously darkened hair

    • Repairing banding from layered colour

    • Transitioning box dye into something dimensional and wearable

    Every head of hair is different. Every correction is personalised.

  • Most colour correction clients don’t book feeling confident. They book feeling frustrated and anxious.

    They’ve been told their hair is “too hard”.

    They’ve had colour layered over colour without explanation.
    They feel like something is off but can’t articulate what.

    This is where trust matters.

    Your appointment begins with a proper consultation - not a rushed glance in the mirror. 

    We’ll talk through what happened, what you asked for, what you don’t like now, and what your end goal actually is.

    Photos are helpful here. Not to copy blindly, but to understand tone, brightness, and softness. Together, we break it down so you feel clear before anything changes.

  • Your hair history is assessed properly. Undertones are identified. Previous colour saturation is considered. The condition of your hair is respected.

    Sometimes that means:

    • Adjusting tone first before lifting further

    • Lightening gradually over staged appointments

    • Breaking up heavy colour with soft dimension

    • Supporting the process with strengthening treatments

  • Colour correction appointments are more detailed than standard colour services. They take time because they require care.

    We’ll explain:

    • What can realistically be achieved in your first session

    • Whether your goal will need to be staged

    • How to maintain and protect your hair between visits

    In many cases, once correction is complete, clients transition into balayage, lived-in colour, or blonde hair packages with a clean foundation.

  • Correcting colour doesn’t mean stripping everything back aggressively. It means understanding how pigment behaves and working with it intelligently.

    Hair health is prioritised throughout the process. If needed, targeted treatments are incorporated to maintain strength and shine.

    You’ll also receive guidance on professional haircare to protect your investment at home. What you use between appointments matters, especially during corrective phases.
