Redken's Color Extend Blondage Express Anti-Brass Mask is an ultra-pigmented purple hair mask for blonde hair that ensures brighter, cooler blonde hair colour. Featuring a powerful toning formula, this hair mask helps to correct and neutralise unwanted yellow and orange undertones in even the brassiest blondes.

To use: After shampooing, towel dry hair. Wearing gloves, apply mask to hair, avoiding scalp area. Comb through for even distribution. Leave on for 5-10 mins, depending on desired neutralisation. 5 mins for subtle neutralisation, 10 mins for maximum neutralisation. Rinse thoroughly. In case of contact with eyes, rinse immediately.
