redken acidic bonding shampoo line of hair repair and recovery products is the go-to for colour treated tresses, offering a range of options from gentle cleansing shampoos to intense conditioners. One of their most popular and powerful collections is the Acidic Bonding Concentrate Sulfate-Free Shampoo & Conditioner Duo, designed to help strengthen weakened bonds and minimise colour fade and damage.

The first step in the collection is the Intensive Pre-Treatment, a fortifying treatment that works to strengthen strands and prevent future damage. It’s best to apply this product before you begin your usual hair care routine as it works by targeting the weakest areas of your strands and providing deep conditioning, nourishing, and strengthening them before you lather up with your favourite shampoo.

Suitable for all hair types, this product is formulated with Citric Acid and Redken’s Concentrated Bonding Care Complex to help shield weakened bonds within your strands, boosting strength and improving elasticity. It also works to rebalance the natural pH levels of your mane, protecting against negative effects of hair colouring, styling tools and even water.

After you’ve thoroughly cleansed your strands, the sulfate-free shampoo is followed by the corresponding conditioner which provides a richer, more intensive moisturisation for your tresses. It helps to reduce the appearance of colour fading and promotes a healthy-looking gloss and shine.

Infused with the same powerful ingredients as the sulfate-free shampoo, this hydrating conditioner helps to strengthen your strands whilst delivering intense conditioning and promoting a silky soft finish. This product also contains an acidic pH which protects your strands from damage caused by heat styling, helping to protect the look of your coloured locks from further colour fade and hair breakage.

The whole Acidic Bonding Concentrate range is easy to use and is a must-have for anyone who colours their tresses or uses frequent hot tools. It’s a reparative system which offers noticeable results, helping to reduce breakage by 56 percent, visibly reducing split ends by 82 percent and leaving your hair up to 11x smoother. As a bonus, this collection is gentle enough to be used every day, making it the perfect choice for those who want to tame frizz and keep their tresses shiny, healthy-looking, and gorgeous.
