Redken Extreme Strengthening Shampoo for Damaged Hair, 250ml — Protein Repair & Breakage Reduction

Redken Extreme Shampoo is a protein-rich strengthening shampoo designed to cleanse and reinforce damaged hair from root to tip.

Formulated for hair weakened by styling, chemical treatments or everyday wear, this professional-strength shampoo uses Redken's targeted protein delivery to rebuild and protect strands. The formula combines an RCT-inspired Strength Complex with amino acids, arginine and citric acid to support resilience, reduce breakage and improve surface smoothness without weighing hair down. Use it as the cleansing step in the Extreme system to prepare hair for conditioners and treatments that continue repair.

How does this shampoo repair weakened hair?

Redken Extreme Shampoo relies on a focused protein complex that addresses damage at multiple levels of the strand. Proteins and amino acids work to reinforce the inner fiber, arginine strengthens the hair structure, and citric acid helps smooth and seal the cuticle for less friction.

• RCT-inspired delivery for root, core and tip nourishment
• Amino acids and protein to fortify hair fiber
• Arginine to support strand strength and elasticity
• Citric acid to smooth cuticles and protect shine

Will it help reduce split ends and breakage?

While no shampoo can permanently eliminate existing split ends, this formula reduces the risk of future breakage by reinforcing weak points and improving manageability. Regular use helps hair resist mechanical stress from brushing and styling, so fewer strands snap over time.

• Strengthens compromised sections to limit snapping
• Smoother cuticles decrease friction-related damage
• pH-balanced cleansing to maintain hair integrity
• Works best paired with conditioners and leave-ins from the Extreme range

How should I use Redken Extreme Shampoo in my routine?

Apply to wet hair, lather, and rinse thoroughly; repeat if hair is very oily or product-laden. For optimal results, follow with Extreme Conditioner or a strengthening mask to lock in protein benefits and restore moisture balance.

• Wet hair and massage shampoo through lengths and scalp
• Rinse and repeat for heavy buildup or extra conditioning
• Pair with Extreme Conditioner or a professional treatment
• Safe for daily use on damaged hair types

Is this suitable for colored or chemically treated hair?

Yes — the gentle, pH-balanced formulation is compatible with color-treated and chemically processed hair. Its strengthening ingredients focus on fortifying and smoothing without stripping color or adding excessive weight.

• pH-balanced to protect color longevity
• Non-stripping cleansing action for treated hair
• Strength complex helps mitigate damage from bleaching and heat
• Integrates into salon-recommended repair regimens

Who this is for: Redken Extreme Shampoo is intended for anyone with fragile, brittle or distressed hair seeking a professional-strength cleansing step that prioritizes repair. Ideal for people who frequently heat-style, color, or chemically treat their hair—or for anyone noticing increased breakage, rough texture or dullness. Use within a complete strengthening routine to maximize resilience and manageability.
