Redken Blondage Express Anti-Brass Mask (formerly Color Extend Blondage Express Anti-Brass Mask) is an ultra-pigmented purple hair mask and deep conditioner that neutralizes yellow and brassy tones in blonde hair in as little as 5 minutes.
Its powerful violet toning formula colour-corrects even very brassy blondes for a cooler, brighter result. You choose the strength by timing: about 5 minutes for subtle neutralization, up to 10 minutes for maximum effect. Arginine, glutamic acid, serine and a hydrolyzed wheat protein are included in the conditioning base.
Apply after Blondage Shampoo to towel-dried hair, wearing gloves and avoiding the scalp. 8.5 oz (250 ml).
