Chroma Absolu Anti-frizz Thermic Leave-in Serum by Kérastase is a moisturising formula that cares for colour-treated hair while intensively shielding and protecting against multiple external aggressors: UV induced damage, humidity, heat and oxidative stress. With powerful antioxidant properties, it helps protect hair and colour. Hair is 96% more moisturized and instantly softer with reduced porosity and long-lasting protection against humidity and water molecules in the air. How to use: • On towel-dried hair, apply 6 to 10 sprays, depending on the length and thickness of the hair. Spread down to tips, then comb to evenly distribute the product. Proceed to blow-dry or air dry. • Lactic Acid – a gentle fibre resurfacer, this healing acid helps to transform, smoothen and seal fibre surface. • Centella Asiatica – a millenary regenerative plant widely used in Asian skincare, known for its caring, healing properties.
