To preserve your bottle blonde shade, start with Redken Color Extend Blondage Shampoo, formulated to gently cleanse strands without stripping the hair of moisture or color. The shampoo is tinted purple in order to prevent blonde hair from turning brassy, and features a Triple Acid Protein complex to tone, strengthen and brighten hair for your best blonde hair ever. By banishing the brass and bringing out your blonde, it'll also allow you to delay your hair touch-up appointments, so you don't have to go back to the salon chair so soon. Bottle-blonde bombshells: this conditioner is for you. When applied to the hair, Redken Color Extend Blondage Color Depositing Conditioner will detangle strands left fragile from processing, soften strands, and, with its purple tint, prevent brassiness.
