amika The Kure Strength Repair Shampoo is a sulfate-free, bond-fortifying shampoo for dry, damaged hair that cleanses with a rich lather while working to strengthen strands weakened by heat, colour and chemical services. It is the same shampoo previously sold as The Kure Bond Repair Shampoo; amika has since renamed the collection "strength repair".
The formula combines amika's bond fortifying technology, which targets the bonds in hair most prone to breakage, with mango and shea butters, borage and avocado oils, hydrolyzed quinoa as a plant-based protein, and sea buckthorn oil, amika's signature superfruit ingredient. amika recommends it for all hair types from 1 to 4c that are dealing with damage, with high-porosity hair as the best fit.
In amika's clinical testing, hair was 2x stronger with 55% less breakage after one use when the shampoo was paired with The Kure Strength Repair Conditioner, and the pair was shown to be safe for colour-treated hair. The shampoo is vegan certified, cruelty-free, paraben-free and keratin safe.
