Redken Blondage Shampoo (formerly Color Extend Blondage Shampoo) is a violet-pigmented purple shampoo for blonde hair that neutralizes brassy, yellow undertones and keeps blonde colour cool and bright.
The highly concentrated purple pigment tones as you wash, and a hydroxypropyltrimonium hydrolyzed wheat protein plus the amino acids arginine, glutamic acid and serine help strengthen the hair. The formula is pH balanced. Leave the second lather on for 3 to 5 minutes for maximum toning.
Wear gloves when applying, as the pigment can stain. Pair with Blondage Conditioner. Available in 10.1 oz (300 ml) and 33.8 oz (1000 ml).
