Coloured hair radiance: our advice
Hair colouring opens the cuticle: the hair fibre becomes more porous, the colour fades and radiance diminishes. To maintain luminous highlights, we seal the cuticle, limit fading and nourish.

Key points to remember
- Hair colouring opens the cuticle: hair becomes more porous, colour fades and radiance diminishes.
- Fading is accelerated by frequent washing, hot water, sun and chlorine.
- Protect with care products for coloured hair, lukewarm water and heat/UV protection.
- Nourishing and sealing the cuticle = more highlights.
- Spacing out washes and choosing a gentle shampoo prolongs colour.
Why does coloured hair become dull?
Hair colouring alters the hair fibre: to deposit pigments, it lifts the cuticle. As a result, the hair becomes more porous, retains pigments and water less effectively, and reflects less light. With every wash, some of the colour escapes and radiance diminishes.
How can you preserve colour radiance?
- Use care products formulated for coloured hair, which protect the pigments.
- Wash with lukewarm water and finish with a cool rinse to tighten the cuticle.
- Space out washes: each shampoo fades the colour a little.
- Protect from sun and chlorine, which oxidise and dull the colour.
- Limit heat and apply a heat protectant.
Steps that prolong colour
- Wait 48 hours after colouring before the first shampoo.
- Use a regular nourishing mask to coat the hair fibre.
- Occasionally use a colour-depositing treatment suited to the shade (anti-yellowing for blonde hair, for example).
- Rinse hair with clean water before going to the pool or sea so it absorbs less chlorine/salt.
