Chroma Absolu

The hero product in our Chroma Absolu range, Soin Acide Chroma Gloss, is a first for Kerastase. The resurfacing, high-shine hair treatment contains a potent blend of 0.7% Lactic Acid and Centella Asiatica. This combination of powerful ingredients starts by treating the hair fibers before sealing the surface of the hair to trap the actives into your strands. The Soin Acide Chroma Gloss not only leaves your hair feeling healthier, but it transforms the surface for 70% more shine*, less porosity (than can lead to color fade) and reduced frizz.

Soin Acide Chroma Gloss's Key Ingredients

For serious shine, strong strands and less porosity for prolonged hair color intensity, Soin Acide Chroma Gloss leans on two key ingredients: Lactic Acid and Centella Asiatic.


3 vials with liquid, including two clear and one pink formula

Lactic Acic: this healing acid helps to transform, smoothen and gently resurface hair fibers. At the optimal 0.7%, it gently exfoliates the hair increasing the permeability of your strands. This means that frizz-fighting moisture can enter before the lactic acid seals the cuticles closed once again for ultimate shine.




Centella Asiatica: A regenerative plant that strengthens and soothes hair, whilst supporting healthy hair growth.










How to Use Chroma Absolu Soin Acide Chroma Gloss for Best Results

  1. Apply to shampooed and towel-dried mid-lengths and ends until saturated.
  2. Apply one dose if you have fine hair or two doses for thicker or longer hair.
  3. Leave on for 1-2 minutes and rinse thoroughly.

So easy, yet so effective. The gloss color hair treatment should be used once a week, or as often as recommended by your hairdresser. It should replace the Soin Fondant or Masque. However, for deeply sensitised hair, it can be used after the Soin Fondant or Masque for extra care and shine.
