Tech is in the hair

Hair is part of our DNA. For decades, we have listened to the silent language of hair fiber – its biology, its resilience, and its diversity. Today, L'Oréal is pioneering its next chapter. Backed by the world's most extensive hair science database, we are decoding each hair texture and scalp at a depth of accuracy that was previously out of reach. This intimate knowledge is bringing new hair & scalp routines: - in the salons through K-SPA by Kérastase, a new luxury scalp care experience bringing together K-Scan, the first AI-powered smart camera for predictive scalp and hair diagnosis, and K-STATION, a tool maximizing our formula's performance with optimized ingredient penetration in the outer layers of the skin - or at home with the Light Straight™ + Multi-Styler which harnesses infrared light to style hair at significantly lower temperatures. Behind these innovations lie the hair digital twin — L'Oréal's 3D virtual model of every hair type, which serves as our map for predicting how any formula will perform, long before physical testing begins.
