This mask, enriched with camellia oil, nourishes the fibre and leaves it silky. Its acid pH seals scales and fixes the colour. Protected and held inside the fibre for longer, colour is enhanced and radiant. After a colouring, the hair loses part of its colour. This treatment lifts the scales of the hair fibre which then becomes permeable. By penetrating inside the fibre, the water dries the hair out and tarnishes the colouring. Without targeted care, the structure of the hair fibre degrades quickly, the hair becomes coarse and the colouring loses its radiance. Colour Protect mask prevents coloured-hair from drying and tarnishing thanks to the highly nourishing properties of camellia oil and a vegetal antioxidant. Its vegan formula has an acidic pH that seals the scales of the hair fibre. Protected, retained longer in the heart of the hair, the colour is vibrant and the hair is intensely silky. Colour Protect Mask contains 92% naturally derived ingredients. Its vegan formula is sulphate-free and silicone-free. Principal natural active ingredients:- Camellia oil: nourishes and brings shine. Camellia flower extract: vegetal antioxidant that protects against external aggressions.
