When you leave the salon, your colour looks bright, glossy and perfectly toned.

Then a few washes later… something shifts.

Your blonde looks brassy.

Your brunette turns coppery.

Your red fades.

Your grey starts yellowing.

After 16 years specialising in colour, I can tell you — it’s usually because of what happens after you leave the chair.

Let me explain.

 

What Actually Happens During a Colour Appointment

Any time your hair is chemically coloured, the structure of your hair is altered.

Colour or bleach is mixed with peroxide. The strength of that peroxide determines:

• How much natural pigment is lifted

• How deep the colour penetrates

• How much the cuticle needs to open to achieve your desired result

Even when done beautifully and carefully, this process opens the cuticle to allow pigment inside the hair shaft.

If that cuticle isn’t supported afterwards, it remains more porous — which means:

• Colour escapes more easily

• Hair oxidises faster

• Shine is reduced

• Brassiness appears

This means that colour longevity isn’t just about pigment, it’s about cuticle integrity.

 

How to Keep Your Colour Fresher for Longer

The key principles apply across all shades:

• Restore the cuticle with protein

• Restore moisture levels

• Reduce heat exposure

• Minimise cuticle stress as much as possible

• Protect from UV and environmental oxidation

 

Let’s break it down by colour.

Jump to your shade:

• Blondes

• Brunettes

• Reds & Coppers

• Silver, Grey & White

 

For Blondes

Common Issues:

• Toner fading → brassiness

• Dullness

• Hair appearing darker instead of brighter

What Blonde Hair Needs

Blonde hair is really fragile. If hair were fabric, blonde would be tissue paper.

The brighter the blonde, the more important these following things are:

• Protein support

• Deep hydration

• Gentle handling

Without protein and moisture, your cuticle can't hold toner properly.

What to Do

• Stretch your wash cycle whenever possible

• Use treatment-based, sulphate-free cleansing 

• Limit flat irons and curling wands

• Reduce heat temperature wherever possible

 

Hydration  + protein used together smooths the cuticle.

A smooth cuticle reflects light.

Light reflection = brighter blonde.

A Note on Purple Shampoo

Overusing purple or blue shampoos can actually make blonde hair look darker and dull.

When hair is porous, it absorbs pigment unevenly - so Instead of neutralising brassiness, it builds on top of it.

A better approach:

1. Wash with a *hydrating, sulphate-free shampoo first 

2. Condition and comb through evenly

3. Rinse

4. Apply toning shampoo briefly for even distribution

5. Rinse thoroughly

Think of hydration as a primer. Tone should be the finishing touch, not the foundation — and by prepping with this extra step, it means you're not using your blonde shampoo to 'cleanse' the hair — you're using it purely for toning, which means less chance of it grabbing onto your hair unevenly. 

Blonde shampoo can be tricky — it's why I actually prefer using a Blonde Conditioner/Treatment (I have one in the works for ROBE) but, by understanding how they work and knowing how to avoid the downsides — you can still get good results with them. 

*See below for my recommendations

 

My Product Recommendations For Blonde Hair

Blonde hair needs protein support and deep hydration to hold toner properly and reflect light.

I highly recommend using the Youthful range if your hair feels really coarse and  dry from highlighting (and for anyone who gets a scalp bleach.)

If your hair is on the fine-medium side, but feels dehydrated and weakened from highlighting or bleaching, I recommend The Lengthening range, because its a perfect balance of hydration and strengthening without too much weight.

For your treatment between washes, I recommend The Leave-In Treatment. 

I created it to have both protein and moisture in balanced amounts - so it's the perfect choice for blonde hair of all textures, and I recommend using it after every wash.

If your hairline is fragile (most blonde hair is prone to breakage around the face) I recommend the Sleek + Treat which can be applied at night, or used as an intensive strengthening treatment/styling product. 

 

For Brunettes

Common Issues:

• Fading into red or copper tones

• Lacking shine

Brunette fading is often oxidation from UV exposure and environmental stress.

To maintain rich, glossy brown tones:

• Use antioxidant-rich formulas

• Keep the cuticle smooth and sealed

• Protect from sun exposure

The smoother the cuticle, the glossier the result.

 

Product Recommendations For Brunettes

To keep brunette tones rich and glossy:

The Youthful Range  is great or antioxidant protection against UV fading, because it contains Sea Moss — a natural UV protectant.

The Tonic to support scalp health, and for UV protection (being antioxidant-rich, it also helps to prevent colour fade on the high-points of the hair that are exposed to sun.)

For the mid-lengths and ends, I recommend The Leave-In Treatment, for shine and cuticle strength.

 

For Reds & Coppers

Red pigment molecules are smaller and more unstable, which is why red fades fastest.

Also, quite often the hair needs to be bleached first before the red is applied — which means the cuticle is already weakened.

This means that the less you disrupt the cuticle between your colour appointments, the longer your red will stay vibrant.

To preserve red tones:

• Wash less frequently

• Avoid excessive heat styling

• Choose gentle cleansing

• Prioritise conditioning

 

Product Recommendations For Reds & Coppers

Red fades fastest — so gentle cleansing is key.

I recommend:

• Clean + Finish for low-friction cleansing — by using a 3-in-1, you're reducing the potential of colour fade in each extra step that requires rinsing, and it will help to replace the moisture that was lost in the colouring process.

• The Leave-In Treatment is perfect for using in between washes, to protect mid-lengths and ends, because it contains both protein and moisture.

 If you prefer a lathering product over the Clean + Finish, I'd suggest The Youthful range, for its sulphate-free antioxidant protection against UV fading.

With Reds, the less you disrupt the cuticle, the longer the colour lasts.

 

For Silver, Grey & White Hair

The most Common Issues for naturally white hair are yellowing and uneven brightness.

These are often caused by:

• UV exposure

• Environmental pollutants

• Hard water (often containing minerals that can build up and lead to staining.)

Grey hair lacks pigment, making it more vulnerable to oxidation.

The solution is antioxidant support, hydration and UV protection to prevent yellowing before it begins.

My Product Recommendations For Silver, Grey & White Hair:

I recommend:

• The Youthful Range for hydration and environmental protection

• The Leave-In Treatment to smooth porosity and increase shine

Hydration equals brightness when it comes to grey hair.

A purple shampoo or conditioner can be useful too (see the note within the Blonde section above.)

 

The Real Secret to Long-Lasting Colour

Colour longevity isn't just about fighting fading.

It’s about strengthening the hair so it can hold colour properly.

Healthy hair:

• Reflects light

• Resists oxidation

• Retains tone

• Feels stronger between appointments

Colour longevity is a hair health issue first — a pigment issue second.

My Final Thoughts

If your colour isn’t lasting, it doesn’t mean you need stronger toner.

It means your hair needs more support.

With the right balance of protein, hydration, UV protection and gentler styling habits, your colour can stay fresher, brighter and glossier for longer.

And that means fewer emergency salon visits.
