Formulated with a very mild emulsifying, softening & volume-enhancing base, Klorane’s Centaurea extract prevents the yellowing process of white or grey hair. KLORANE Anti-Yellowing Shampoo with Centaury acts by restoring radiance in the hair by adding silver highlights thanks to the cyanocentaurein it contains. These are only highlights as the effect is external. Centaurea is a harvest plant, commonly seen in Europe & Western Asia. Harvest of its flowers is performed during floral booming. These flowers are then dried in the shade & in airy premises to ensure that their original colour is kept. The extract obtained from dried plants contains a natural blue colouring agent called cyanocentaurein. No artificial colours. Hypoallergenic. Paraben free.
