That’s because the \u003cstrong\u003eBonding Care Complex\u003c\/strong\u003e helps repair your hair’s weakened structure from within. Damaged hair often has a higher pH value, leaving the outer layer open and moisture escaping. \u003cstrong\u003eCitric acid\u003c\/strong\u003e restores pH to a healthy level, closing the cuticles and reducing frizz while making styling easier.\u003c\/p\u003e\n\u003cp\u003eThe shampoo gently cleans thanks to its sulphate-free formula, and the conditioner finishes the treatment with Silicones that leave your hair smooth and protected. Regular colour or bleach users notice their hair feels less straw-like and their colour stays brighter after a few weeks. The \u003ca href=\"https:\/\/www.haarspullen.nl\/en\/collections\/redken\"\u003eRedken\u003c\/a\u003e Acidic Bonding Concentrate line offers a complete approach that works with every wash.\u003c\/p\u003e\n\u003ch2\u003eIs the Redken Acidic Bonding Concentrate line suitable for coloured hair?\u003c\/h2\u003e\n\u003cp\u003eYes, the Redken Acidic Bonding Concentrate line is specially designed for coloured and chemically treated hair. The formula helps slow colour fading, keeping your shade vibrant longer.\u003c\/p\u003e\n\u003cp\u003eThe low pH shampoo seals the cuticles after washing, exactly what coloured hair needs. Colour molecules stay locked in the shaft longer. Whether you have highlights or full colour, you’ll see fresher colour and more shine after a few weeks.\u003c\/p\u003e\n\u003ch2\u003eCan I use Redken Acidic Bonding Concentrate Shampoo every wash?\u003c\/h2\u003e\n\u003cp\u003eYou can use Redken Acidic Bonding Concentrate Shampoo every wash, but we recommend alternating with a hydrating shampoo if your hair is fine or sensitive.\u003c\/p\u003e\n\u003cp\u003eDaily use on fine hair may feel slightly drying for some. Washing two to three times a week? Then you can use Acidic Bonding Concentrate every time without issue. If you have a sensitive scalp or itchiness, start with once a week and watch how your skin reacts.\u003c\/p\u003e\n\u003ch2\u003eDoes the Redken Acidic Bonding Concentrate set contain Silicones and sulphates?\u003c\/h2\u003e\n\u003cp\u003eThe shampoo is sulphate-free; the conditioner does contain Silicones. These are two different things with separate functions.\u003c\/p\u003e\n\u003cp\u003eThe sulphate-free shampoo gently cleans your hair without stripping natural oils, important for damaged and coloured hair. The Silicones in the conditioner leave your hair feeling smoother and easier to comb after washing. If you follow the curly girl method or want to avoid Silicones, the conditioner may not suit you. Instead, check out other products in the \u003ca href=\"https:\/\/www.haarspullen.nl\/en\/collections\/producten-speciaal-voor-beschadigd-haar\"\u003eDamaged Hair\u003c\/a\u003e category.\u003c\/p\u003e\n\u003ch2\u003eDamaged hair? Why the ABC routine works better than single products\u003c\/h2\u003e\n\u003cp\u003eMany shampoos just clean without considering damaged hair’s needs. The Redken Acidic Bonding Concentrate line works differently: shampoo and conditioner share the same active bases and enhance each other’s effects. The shampoo opens the cleansing process at the right pH, the conditioner seals it off. Using them together gives a cumulative result that single products can’t match.\u003c\/p\u003e\n\u003cp\u003eCompared to more sustainable bond-building lines like Olaplex, Redken Acidic Bonding Concentrate offers similar daily results at a friendlier price per wash.
