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.

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.

- Glycerin — humectant; retains moisture

Benefits:
- Combats 1 year of visible damage in 1 use (system)
- 56% reduction in breakage; 9× smoother hair

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.

Customer photo review of Redken Acidic Bonding shampoo 300ml

I am never without my Acid Bonding Shampoo and Conditioner. It leaves my hair soft, shiny and protected

Great product!

Terrible. Far too heavy for fine hair even when using a tiny amount. Won't buy again. Used it twice and very disappointed.

Best purchase for my hair.

Superfast delivery. Amazing product. Will order again.

This shampoo doesn't clean my hair properly, even after a good three to four washes.

I love the shampoo! Hair feels soft and silky , I have very dry hair so this shampoo is the best , makes hair manageable Thank you

Love this shampoo, leaves my hair shiny and full of life.

Love the sale items! Helps to keep my hair looking and feeling good. Big difference with only 1 wash. Fantastic product. Delivery was also fantastic - thank you.

I have highlighted hair and I love that it nourishes and maintains my highlights without being overly heavy! Definitely recommend

Really helped with my hair breakage

Redken Acidic bonding shampoo 300ml

Love this shampoo! Does not leave any buildup. Hair feels soft, shiny & healthy! Pleasant scent too.

Partners always delivers super quick! I am loving the shampoo so far - subtle smell and my hair feels clean and soft - I will have to see how it fairs the more i use it. I also purchased the conditioner with the Shampoo - leaves my hair soft!

Love it! My hair feels amazing after using this.

I have only used salon shampoos and conditioners for years as I have very fine but coarse (difficult!) hair. This shampoo has been a game changer for me. My hair is in better condition and much easier to handle and style. I will definitely be purchasing again.

The best of the best u don't even need any heat on ur hair it makes ur hair sleek

I absolute love this shampoo. Very few shampoo's work with my hair but this one definitely does. Does not weigh my fine blonde hair down and it feels clean and soft afterwards. The whole range is incredible. Will keep repurchasing

Hair feels fresh and clean and loving the shine highly recommend this product. Speedy delivery and awesome service.
