Which products should you avoid after plant-based hair colouring?
You come home from the hairdresser and your hair feels different. Softer. Fuller. Shinier. The colour moves with the light and gives your hair that typical natural depth that is so characteristic of plant-based hair colouring. Not a flat or “harsh” result, but warm nuances and reflections that subtly change depending on how the light hits them.
But a few weeks later, your colour may sometimes seem less intense. Your shine becomes softer, your hair feels drier or your reflections are less visible. Many people then wonder: “Why does my plant-based hair colour fade so quickly?”
Yet this is often not due to the plants themselves.
In most cases, the difference lies in the products you use afterwards. Because even though plant-based hair colour is gentle on the hair, it still requires an adapted routine. Some shampoos, conditioners and styling products can affect the plant pigments more quickly, meaning your colour stays beautiful for less time.
Which products should you avoid after plant-based hair colouring? You will discover it in this complete guide.
Why your routine after plant-based hair colouring makes such a difference
Plant-based hair colouring works completely differently from conventional oxidative hair colour.
Chemical colouring opens the hair cuticles and changes the natural pigment deep inside the hair fibre. Plant-based hair colour does not do this. It coats the hair with natural pigments from plants, flowers, herbs and bark. As a result, the hair structure remains intact and the hair often feels stronger, fuller and healthier after colouring.
This coating effect is also what creates the typical shine of plant-based hair colour.
But precisely because the pigments sit around the hair fibre, your colour reacts more sensitively to the products you use afterwards. Anything that cleanses too aggressively, dries out the hair or leaves behind a synthetic layer can affect the shine, depth and intensity of your plant-based colour.
A healthy hair fibre holds plant pigments better and reflects light more beautifully.
That is why a good routine after plant-based hair colouring is mainly about gentleness, nourishment and protection.
Which shampoos should you avoid after plant-based hair colouring?
One of the most common mistakes after plant-based hair colouring is using a shampoo that is too aggressive.
Many conventional shampoos contain powerful sulphates such as Sodium Lauryl Sulfate (SLS) or Sodium Laureth Sulfate (SLES). These ingredients create a lot of foam and a strong “clean” feeling, but they often cleanse far too intensely.
The problem? They do not only remove dirt and excess sebum, but also the protective layer around the hair fibre. And that is exactly where the plant pigments are located.
As a result, your colour can fade faster, lose shine and look dull more quickly.
Aggressive shampoos can also dry out the scalp, which often leads to:
- a tight feeling
- irritation
- itching
- hair that becomes greasy faster as a reaction
Many people do not realise that their shampoo may be the reason why their plant-based hair colour does not stay beautiful for as long.
Be careful with anti-grease shampoos and clarifying formulas
Do you have hair that gets greasy quickly? Then an anti-grease shampoo may seem logical. However, these shampoos are not always ideal after plant-based hair colouring.
Many “purifying” or “clarifying” shampoos contain strong degreasing ingredients that remove product residue, silicones and oil. That may sound positive, but they can also affect the plant-based coating around your hair.
The result is often that your colour looks dull faster and your hair feels drier.
Especially when you wash your hair daily with these shampoos, plant-based reflections can become softer more quickly.
When a detox can be useful
Avoid silicones in shampoo, conditioner and styling products
Silicones are probably one of the most underestimated causes of dull hair after plant-based hair colouring.
At first, they seem great. Your hair feels smooth, soft and frizz-free. But this effect often comes from silicones forming a synthetic layer around the hair fibre.
Over time, these layers can build up.
As a result:
- the hair looks duller
- the hair fibre becomes coated
- natural hydration becomes more difficult
- new plant pigments may adhere less beautifully
Many people then think their colour is fading, while in reality the hair is simply becoming “covered”.
How to maintain shine without synthetic films
The most beautiful shine after plant-based hair colouring does not come from silicones, but from a healthy hair fibre with beautifully closed hair cuticles.
That is why conditioners that hydrate and close the hair cuticles are much more interesting. Hairborist Natural Color, for example, is a conditioner based on organic apple cider vinegar that helps close the hair cuticles, enhance shine and fix plant-based hair colour.
For styling too, it is best to choose products that support the hair without weighing it down or sealing it off. Think of a light natural mousse for volume, a serum based on plant oils for the ends or a gentle hairspray that fixes the hairstyle without leaving behind a hard, synthetic layer.
This way, you maintain shine, softness and movement, without heavy silicones or artificial films that can make your plant-based colour look duller over time.
Be careful with heavy masks full of film-forming agents
Many commercial hair masks give an immediate feeling of softness. But not every mask truly nourishes the hair.
Some masks mainly work with heavy film-forming agents that temporarily smooth the hair fibre. The hair may feel soft, but it does not necessarily become stronger or healthier.
After plant-based hair colouring, what you need is a treatment that supports the hair fibre without weighing it down.
Why nourishing masks remain important for colour maintenance
Well-nourished hair reflects light better. As a result, your colour automatically looks more intense, shinier and more vibrant.
A nourishing mask also helps prevent dryness, which is important because dry hair can look dull more quickly.
The Hairborist Karité Mask was developed as an ultra-nourishing organic mask for dry, damaged, coloured or curly hair.
By regularly adding nourishment, your plant-based hair colour continues to look more vibrant between two colouring appointments.
Avoid chemical straightening or aggressive treatments right after your colour
Plant-based hair colouring respects the hair structure. Chemical straightening treatments and aggressive technical treatments often do the opposite.
They open and intensely alter the hair fibre, which can make the plant-based pigment layer less stable.
Especially with colours containing indigo, chemical treatments can sometimes cause unexpected reactions.
Excessive heat from straighteners or very hot blow-dryers can also dry out the hair and reduce the shine of plant-based reflections.
Why professional advice remains important
Do you still want to have another treatment after plant-based hair colouring? Then it is best to have this assessed by a hairdresser with experience in plant-based colour.
They can evaluate:
- how porous your hair is
- which pigments are present
- whether your hair is strong enough
- which timing remains safe
This helps prevent unwanted colour reactions or damage.
Be careful with styling products high in alcohol
Styling can also influence how long your plant-based hair colour stays beautiful.
Many styling products contain alcohols that evaporate quickly. This helps create volume, hold or fixation, but it can also dry out the hair when used often.
And dry hair reflects less light. As a result, your plant-based colour may look less shiny, even when the pigments are still present. Your colour has not necessarily disappeared, but your hair may lack softness, nourishment and light reflection.
That is why, after plant-based hair colouring, it is better to choose natural styling products that shape your hair without making it hard, stiff or dry. Styling should not work against your colour, but rather complement your hair care routine.
Which styling products are better suited to plant-coloured hair?
It is better to choose styling products that remain flexible and do not seal the hair under a heavy layer. The goal is a natural result with movement, shine and protection.
Within the Hairborist range, you can use, for example:
- Foam Lotion for natural volume without weighing the hair down
- Hairtonic with apple cider vinegar for a smooth, frizz-free finish
- Pure Natural Serum with plant oils to protect and soften the hair while adding extra shine
This way, styling does not become a separate step that weighs your hair down, but an extension of your care routine. You style your hair while also supporting the softness, shine and natural look of your plant-based hair colour.
Avoid too much product build-up
When your colour becomes a little softer, the reflex is sometimes to use more products. More oil. More serum. More styling. More leave-in.
But too many layers can actually weigh your hair down and make it look duller. Especially with plant-coloured hair, you want to avoid coating the hair fibre with a build-up of products. Your colour has not necessarily faded, but your hair reflects less light, making it appear duller.
Plant-coloured hair usually prefers simplicity: gentle cleansing, good nourishment and light styling. So it is not about using more products, but about using the right products at the right time.
Which products are best to use after plant-based hair colouring?
A good routine does not have to be complicated.
Often, all you need is:
- a nourishing oil treatment before shampooing
- a mild shampoo without harsh sulphates
- a regular nourishing mask
- a conditioner that closes the hair cuticles
- light styling without drying ingredients
This combination helps keep the hair fibre healthy, supple and shiny.
How an oil treatment can support your colour
A pre-shampoo oil treatment is often a much better solution than constantly adding extra styling products. Because you apply it before washing, your hair receives intensive nourishment without leaving a heavy layer behind after drying.
At Hairborist, Repair and Renovator are used as nourishing oil treatments that help restore and protect the hair fibre.
These oil treatments can be personalised with colour Aromactifs:
- Nacre for blonde, grey and white hair
- Cuivre for copper reflections
- Ecarlate for red hair
- Ebène for dark shades
This allows you to bring back shine, depth and intensity to your colour without fully colouring your hair again. It is a gentle in-between step when your plant-based hair colour is still beautifully present, but could use a little extra vibrancy.
Conclusion: avoid anything that strips, seals or dries out the hair
Plant-based hair colour evolves with your hair. The healthier your hair fibre remains, the more beautifully your colour will usually develop. That is why colour maintenance is not about “stronger” products, but about gentler hair care.
Above all, avoid products that cleanse your hair too aggressively, seal it off synthetically, dry it out or suffocate it under heavy product layers. Aggressive shampoos, silicones, drying styling products and heavy film-forming agents can make your colour look dull more quickly.
But with the right routine, the opposite often happens. By cleansing gently, nourishing well and protecting your hair, shine and reflections stay visible for longer. Your colour evolves in a natural, harmonious way and your hair remains supple, vibrant and well cared for.
And that is exactly where the strength of plant-based hair colouring lies: not only in colouring the hair, but also in caring for it.
