Which mask should be used for coloured hair?

Colouring is most often done for aesthetic purposes, but it can tend to dehydrate hair fibres and fade over time. To counteract these inconveniences, using a hair mask is highly recommended. Let us explain why!

How are coloured hair characterised?

There are three main types of hair dyes on the market: temporary, semi-permanent, and permanent colourings. Only temporary colourings do not alter the deep structure of the hair; indeed, the molecules that compose them have a high affinity with the hair's keratin and attach to its surface without penetrating the cortex. This is why temporary colourings typically fade after the first shampoo.

However, semi-permanent and permanent dyes act differently. These treatments are capable ofopening the cuticles, penetrating into the cuticle and diffusing into the cortex. Yet, let's remember that the primary function of the cuticle scales is to protect the hair shaft. This action therefore weakens the hair while making it dry. Coloured hair is generally weakened and sensitive to its environment, hence its often dull and tired appearance.

How to properly maintain your coloured hair on a daily basis?

On a daily basis, several steps should be taken to care for your coloured hair.

  • Opt for a gentle shampoo, free from sulfates and silicones.

    Sulphates are surfactants that are widely present in shampoos due to their excellentdetergent properties. Moreover, they are inexpensive and create a significant amount of foam when in contact with water, often seen as a sign of a shampoo's effectiveness by users. However, the detergent power of sulphates is potent and can cause scalp irritations. They damage hair fibres and sometimes trigger allergic reactions. Furthermore, they make hair brittle and split-ended. They also promote a difference in texture between the root (oily) and the ends (dry). Additionally, these harmful effects are usually combined with those caused by the presence of silicone in these types of treatments, which are very occlusive ingredients. In the long run, sulphates and silicones weaken the scalp by diminishing thenatural keratinof the hair. We have developed three shampoos without sulphates or silicones, to address different hair issues (lack of volume, dryness, dandruff).

  • Rinse your hair with lukewarm or even cold water.

    During rinsing, hot water should be avoided as it has aggressive properties on coloured hair, whose cuticles are already weakened. On the contrary, cold water will help the hair cuticles to close.

  • Choose your hair mask wisely.

    After shampooing and conditioning, it is widely recommended to apply a hair mask one to two times per week for coloured hair. Moreover, when the hair is washed and rid of impurities, treatments penetrate more deeply into the hair fibre. Hair masks suitable for coloured hair are generally rich, restorative formulas or specialised treatments for this type of hair. For instance, you could use our repairing hair mask. Composed of 98% natural origin ingredients, this mask deeply nourishes and repairs the hair fibre thanks to the synergy of 3 natural actives: biomimetic ceramides, mango butter, and avocado oil. The hair becomes supple, shiny, and silky.

  • Gently style your hair.

    Limit styling and favour the use of a wide-toothed wooden comb. Carry out the styling immediately after washing your hair and let it air dry. We advise against using a hairdryer on coloured hair.
