The Kérastase Resistance Therepiste Serum is a luxurious and soothing treatment for tired and damaged hair. Over-processing can leave even the healthiest of hair feeling parched and fragile. This serum, created from a specially selected blend of amino acids, binds the surface of each hair strand, improving structure and appearance. The unique FIBRA-KAP™ formula helps to resurface hair, working as both a repairing cream and a preventative measure from further damage. Suitable for the thickest, unruliest manes, this unique treatment conditions and hydrates damaged lengths, leaving them more manageable and healthy-looking. You can also use this serum to protect your crowning glory while heat styling. With protection at temperatures up to 230°C, you can continue to style your hair with your favourite tools, as this hardworking serum helps to reduce breakage and prevent split ends. To use this product, simply apply it to towel-dried hair and massage it through the lengths to the ends. Blow-dry and style as usual, for a sleek and silky look.
