The Redken Extreme Litre Duo is the professional 1-litre shampoo and conditioner for severely damaged, over-processed, or breakage-prone hair — using a fortifying protein complex that fills weakened zones in the hair shaft, rebuilds tensile strength, and reduces breakage from the first wash, in the professional salon size at Canada's lowest price.
What's Included
• Redken Extreme Shampoo — 1 litre (1000ml)
• Redken Extreme Conditioner — 1 litre (1000ml)
Why Buy the Litre Size
• Save 35% vs buying two regular bottles — protein repair works cumulatively, making the litre the economical choice for the consistency results require
• Severely damaged hair needs consistent daily use — the litre ensures you never interrupt the repair routine by running out
• Professional salon size used by colourists who recommend Extreme to clients post-bleach or post-chemical service
• Not available at Sephora in litre size — Zennkai is an authorized Canadian source
• Lasts approximately 3–4 months with daily use for medium-length hair
About Redken Extreme
Redken Extreme is the brand's dedicated repair system for hair that has been pushed past its limit — by bleach, repeated colouring, heat styling, or aggressive chemical services. The protein-fortifying formula works at the level of the damaged fiber, filling weakened and porous sections and rebuilding tensile strength. Widely recommended by Canadian stylists as the daily maintenance system for clients with visibly compromised or fragile hair who need results between appointments.
Key Ingredient
Fortifying protein complex — Redken's concentrated protein blend that fills weakened, porous sections of the hair shaft and rebuilds structural strength from within. Reduces breakage during brushing and styling measurably with consistent use, improving elasticity and resistance to snapping.
Best For
• Severely damaged, over-processed, or fragile hair
• Hair that breaks easily during brushing or styling
• Post-bleach or post-relaxer recovery as a daily maintenance system
• Hair with significant porosity and structural weakness from repeated chemical services
• Anyone rebuilding hair health after a period of over-styling or chemical damage
