FAQ about coloured hair

How should coloured hair be cared for?

To preserve the new colour of your hair, it is advisable to use products formulated specifically for coloured hair and to avoid washing it too frequently, as this may cause the colour to fade.

How can discolouration to yellow be prevented?

The regular use of certain neutralising shampoos (blue or violet), as well as the systematic protection of your hair from UV rays using a sun care product helps to reduce the risk of colour alteration.

Can swimming pool chlorine alter hair colouring?

In theory, if the hair dye is of good quality, it is not supposed to be affected by the chlorine in the swimming pool. Nevertheless, as a precautionary measure, it is advisable to wear a swimming cap to protect the hair in the pool.

Are plant-based hair dyes gentler on the hair?

Plant-based dyes are indeed gentler on the hair and less likely to trigger allergic reactions. Nevertheless, they tend not to last as long.

Can coloured hair be straightened?

The heat from straightening can damage coloured hair fibres, which are already weakened. It is therefore recommended to use a heat-protective treatment before any styling.

Are coloured hair strands more porous?

Yes, because colouring and chemical treatments increase hair porosity by damaging the cuticles. As a result, it allows more water to escape and more readily absorbs active ingredients, but also the impurities present on its surface.

Why does colour fade over time?

Washing, UV radiation and oxidation gradually degrade the pigments. The porous fibre retains the colour less effectively.

Does hot water damage coloured hair?

Yes, it accentuates the opening of the cuticle and promotes the loss of pigments. This can accelerate the dulling of the colour.

Are film-forming agents beneficial for coloured hair?

The film-forming agents, such as vegetable oils, create a protective film that smooths the cuticle and limits external damage. This can enhance shine and reduce pigment loss.

Is it possible to dye your hair frequently without damaging it?

Repeated colouring can weaken the hair fibre. Spacing out applications and adjusting hair care helps to limit this impact.
