Redken Acidic Bonding Concentrate Shampoo is a sulphate-free repair shampoo for damaged, over-processed hair. Powered by Citric Acid and Redken's Bonding Care Complex, it rebuilds weakened internal bonds caused by bleach, colour and heat — while balancing the hair's pH to seal the cuticle and lock in strength. An authorised Redken stockist — 100% authentic, with free SA delivery over R390.

Key Benefits
  • Repairs & strengthens — reinforces weakened bonds for up to 56% less breakage as part of the system.
  • Protects colour — the sulphate-free formula helps salon colour stay vibrant for longer.
  • Smooths & de-frizzes — leaves hair softer and notably smoother, with frizz under control.
  • pH-balancing — an acidic formula that seals the cuticle and guards against hard water and daily wear.
How to Use
  1. Apply to wet hair and massage into a rich lather.
  2. Rinse thoroughly.
  3. Follow with the Acidic Bonding Concentrate Conditioner for full bond repair.
Ingredients

The hero is Citric Acid, an alpha-hydroxy acid small enough to penetrate the cuticle, capture metal ions and reinforce weakened bonds while lowering the hair's pH to seal the surface. It cleanses on a fully sulphate-free, vegan base (Decyl Glucoside, Sodium Cocoyl Isethionate and Cocamidopropyl Betaine), with panthenol and glycerin for moisture.

From the Partners Hair team
Redken Acidic Bonding Concentrate Shampoo is a sulphate-free, bond-repair shampoo for all types of damaged, colour-treated and chemically processed hair. Part of the Redken Acidic Bonding Concentrate range. Citric Acid and the Bonding Care Complex work at the molecular level — penetrating the cuticle, capturing metal ions and reinforcing weakened bonds to deliver ultimate strength repair, intense conditioning and colour fade protection in a single wash.

Best for: all types of damaged hair — bleached, colour-treated, chemically processed or heat-damaged; the cleansing step in the complete ABC system.
Less suited to: heavy build-up requiring a clarifying shampoo; fine hair primarily needing volume (use Volume Injection Shampoo); hair with no damage.

Key actives:
- Bonding Care Complex — reinforces weakened hair bonds at a molecular level; reduces breakage by up to 56%
- Citric Acid (AHA) — pH-balancing acid that penetrates 7 layers deep; captures metal ions and fortifies weakened bonds
- Panthenol (Pro-Vitamin B5) — moisturises and improves elasticity
- Glycerin — humectant; retains moisture

Benefits:
- Combats 1 year of visible damage in 1 use (system)
- 56% reduction in breakage; 9× smoother hair
- Gentle sulphate-free cleansing — colour-safe
- pH-balancing — aligns the cuticle for improved smoothness and shine

How to use: Apply to wet hair, lather, rinse. Follow with ABC Conditioner.

Format: 300ml sulphate-free bond repair shampoo.

Before you buy
Common questions

How does Redken Acidic Bonding Concentrate compare to Olaplex?

Both systems are excellent at repairing damaged hair, but they use different technologies. Olaplex uses a single patented molecule to target disulphide bonds. Redken uses a highly concentrated Bonding Care Complex alongside Citric Acid (AHA) to strengthen weakened bonds while rebalancing the hair's pH to seal the cuticle. Redken ABC is often favoured by those who want intense moisture and softness alongside structural repair.

Is the Redken Acidic Bonding line safe for colour-treated and bleached hair?

Yes — it is designed for it. The entire range is sulphate-free and formulated at an acidic pH, which helps lock the cuticle down. This helps prevent salon colour from washing out and repairs the damage caused by bleaching and highlighting.

Can I use Redken Acidic Bonding Concentrate on fine hair?

Yes. The formulas are concentrated and hydrating but balanced to give weightless repair. If your hair is very fine, rinse the conditioner thoroughly and use a slightly smaller amount of the Leave-In Treatment.
