Infused with the brand’s first multi-repair acid care, the Kérastase Chroma Absolu Mask supports the hair's core strength, promoting shine, vibrancy and smoothness.Ideal for all colour-treated hair, the mask works to combat the visible effects of chemical damage, such as increased fibre porosity, colour-induced frizz and hair oxidisation. Applying with a creamy yet lightweight texture, the formula helps to smooth the hair, seeking to reduce porosity by strengthening damaged strands. Hero ingredient lactic acid gently exfoliates and seals the surface of the hair to reduce frizz and boost shine, while centella asiatica nourishes. The anti-porosity filling mask is ideal for use as part of your coloured hair care routine, providing an intensive treatment.
