Redken Extreme Strengthening Shampoo for Damaged Hair, 10.1 fl oz — RCT Protein Complex & Anti-Breakage

Redken Extreme Shampoo is a strengthening, anti-breakage shampoo formulated with RCT Protein Complex, amino acids, arginine and citric acid to cleanse and reinforce damaged hair from root to tip.

Designed for hair showing signs of mechanical, thermal or chemical stress, this professional-strength shampoo uses Redken's targeted delivery system to rebuild weakened fibers and improve manageability. It gently removes dirt and product buildup while delivering proteins and conditioning agents that work across three hair levels — root, core and tip — to reduce breakage and restore resilience and shine.

How does Redken Extreme Shampoo help reduce hair breakage?

The formula includes protein-building ingredients that strengthen hair structure and help resist snapping. By combining amino acids, arginine and the RCT Protein Complex, the shampoo supports weakened bonds and smooths the hair cuticle for improved elasticity.

• RCT Protein Complex targets root, core and tip for multilayer repair
• Amino acids and arginine reinforce internal hair fibers
• Citric acid conditions and smooths the cuticle to reduce friction

What results can I expect after using it regularly?

With consistent use, hair looks and feels stronger, softer and more manageable. The shampoo helps prevent future breakage and makes styling easier by improving tensile strength and reducing frizz and roughness.

• Visible reduction in split ends and breakage over time
• Smoother texture and improved comb-through wet and dry
• Enhanced shine due to a conditioned, smoother cuticle

How should I use this shampoo for best results?

Apply to wet hair, lather, and rinse; repeat if hair is heavily soiled or product-laden. For targeted repair, follow with Redken Extreme Conditioner or a leave-in treatment to lock in strengthening ingredients and prolong benefits.

• Use daily or as needed on damaged or compromised hair types
• Pair with complementary Redken Extreme products for a full regimen
• pH-balanced formula supports healthy hair mechanics after washing

Is this shampoo suitable for color-treated or chemically processed hair?

Redken Extreme Shampoo is formulated to be gentle enough for many color- and chemically treated hair types while focusing on repair and fortification. It cleanses without stripping and leaves hair prepared for conditioning and further professional treatments.

• Safe for most color-treated hair when used as directed
• Helps fortify chemically stressed strands after services like bleaching or heat styling
• Works well in salon-prescribed care routines to maintain strength

Who is this for: Redken Extreme Shampoo is aimed at anyone experiencing brittle, weakened or frequently styled hair who wants a professional-strength cleansing product that also rebuilds strength. It's a practical choice for salon clients, heat-styling enthusiasts, and anyone seeking to reduce breakage and improve hair resilience without sacrificing gentle cleansing.
