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.

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
- Apply to shampooed and towel-dried mid-lengths and ends until saturated.
- Apply one dose if you have fine hair or two doses for thicker or longer hair.
- 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.
