How does Demi Moore keep her hair soft, silky and extra healthy? It all comes down to her French shampoo. Moore's long-time hairstylist, Dimitris Giannetos, shared exactly how he got her hair ready for Paris Fashion Week in a recent Instagram Reel. The actress's long, shiny strands resembled glass, and the key wasn't in the styling products. Her "soft, fluffy, couture-level bounce" was achieved with the Kerastase Nutritive Bain Satin Riche Shampoo. And yes, it's right on Amazon.
