Formulated for white, grey & platinium blonde hair, this shampoo cleanses hair and reduces any yellowing effect while adding subtle silver highlights. Centaury, Centaurea cyanus L., is selected as for its richness in Cyancentaurein, a vegetal pigment with natural blue hues, proven to reduce yellowing. The cornflowers are grown according to organic farming methods in the Tarn region of France, and the active ingredient adheres to the principles of green chemistry with COSMOS certification. Hair is left soft, easy to style, and reveals all its beauty and radiance.
