Redken Blondage purple shampoo is a color depositing and protecting purple shampoo for blond hair. The Triple acid protein complex strengthens and pure violet pigments remove unwanted brassiness, leaving blond hair cool and bright. Formally known as color extend blondage purple shampoo. I only used once. I have changed my hair coloring so I have no need, but it worked great the one time I tried it.
