Designed for salon-quality repair at home, this 16.9 fl. oz. refill delivers Redken's bonding complex and citric acid in a concentrated, thick formula that coats strands for stronger, more resilient hair. The refill format gives you 25% more value per milliliter and uses 68% less plastic per milliliter, making it a smart choice for both hair health and sustainability. It’s formulated to work on all hair types, including color-treated and highly processed hair, offering conditioning, strength repair, and color fade protection in one step.

How does this shampoo strengthen hair without weighing it down?

The formula combines a targeted bonding complex with citric acid to reinforce weakened internal links while keeping hair manageable. Its concentrated, thicker texture means a small amount spreads easily, covering fibers thoroughly without needing excess product.

• Bonding complex targets and rebuilds compromised hair links.
• Citric acid helps align and seal the cuticle for smoother strands.
• Thick consistency requires less product to achieve full coverage.
• Sulfate-free surfactants cleanse gently to avoid further weakening.

Will it protect my salon color and reduce fading?

The acidic pH helps close the hair cuticle after cleansing, which preserves color pigments and reduces washout. Because it’s formulated without harsh sulfates, it avoids aggressive stripping, helping your color stay truer between salon visits.

• Acidic formulation smooths the cuticle to lock in pigments.
• Color-safe cleansing prevents accelerated fading.
• Gentle surfactants clean without removing color molecules.
• Ideal for frequent color services and touch-ups.

Can it repair damage from heat styling, sun, or chemical services?

Yes—this shampoo is designed to address multiple sources of damage by reinforcing structure and improving resiliency. While it’s not a miracle fix overnight, regular use reduces breakage and prepares hair to better withstand styling and environmental stress.

• Strengthens fibers weakened by heat, bleaching, or chemical treatments.
• Conditions to reduce friction and minimize breakage during styling.
• Improves overall strand resilience to sun and wind exposure.
• Works alongside conditioners and treatments for enhanced repair.

How do I use the refill to get the best results?

Dispense a small amount into your palm and emulsify with water before applying to wet hair; the concentrated texture means less goes further. Massage into scalp and lengths, rinse thoroughly, and follow with a compatible Redken conditioner or treatment for targeted moisture and sealing.

• Use sparingly—concentrated texture spreads well across wet hair.
• Massage gently into scalp and mid-lengths for even coverage.
• Rinse fully and pair with Redken Bonding Conditioner or Mask for deeper repair.
• Refill packaging supports sustainability and cost savings per ml.
