Redken Extreme Shampoo for Damaged Hair, 33.8 fl oz — Strength Complex, Breakage Repair

Redken Extreme Shampoo is a salon-grade repairing cleanser that strengthens weakened hair, reduces breakage, and leaves strands soft and shiny.

This 33.8 fl oz professional-size shampoo is formulated to help restore brittle, distressed hair using Redken's Strength Complex of proteins, amino acids, and arginine, plus citric acid to smooth and enhance shine. It cleanses away product buildup while targeting fragile areas from root to tip to improve resilience and manageability over repeated uses. Use it as the foundation of the Redken Extreme regimen to support stronger-looking hair between in-salon treatments.

How does this shampoo help reduce breakage?

The formula deposits strengthening ingredients that rebuild weakened fiber and reinforce vulnerable sections of the hair shaft. By improving structural integrity, the shampoo lowers the likelihood of snapping during brushing, styling, or daily wear.

• Contains proteins and amino acids that fill and reinforce damaged areas
• Arginine helps support the hair’s natural strength network
• Cleans gently to remove residues that can weigh and weaken strands
• pH-balanced to help smooth cuticles and reduce friction-related breakage

Will it make hair feel softer and shinier?

Yes. Citric acid in the blend helps smooth the hair surface, promoting light reflection for a polished look while leaving hair feeling conditioned. The overall effect is cleaner, more supple hair with improved surface texture after rinsing.

• Surface-conditioning agents smooth the cuticle
• Cleansing plus conditioning reduces roughness and static
• Regular use helps maintain a glossy finish without heavy residue

Is this suitable for all types of damaged hair?

Redken designed Extreme Shampoo for a range of damage types—mechanical, chemical, or heat-related—so it works on fine to coarse hair that needs reinforcement. While safe for most color-treated hair, pairing with complementary Redken treatments delivers more targeted repair for severe damage.

• Formulated to address split ends, brittleness, and general weakening
• Appropriate for chemically processed and heat-styled hair
• Best results when used with other products from the Extreme line

How should I use this to get the best results?

Apply to wet hair, gently lather concentrating on roots and damaged mid-lengths to ends, then rinse thoroughly. For visible improvement, follow with Redken Extreme conditioner or a leave-in repair treatment and use consistently as part of your haircare routine.

• Use 2–3 times weekly or as needed depending on styling frequency
• Pair with a deep-conditioning mask weekly for intense repair
• Comb through while conditioner is in to detangle and prevent breakage

Who is this for: Redken Extreme Shampoo is intended for anyone with weakened, brittle, or distressed hair who wants a professional-strength cleansing formula that supports reinforcement and manageability. It’s especially useful for people who regularly heat-style, color-treat, or chemically process hair and need a salon-caliber product to help reduce breakage and restore a smoother, healthier-looking finish.
