Scalp Care Joins the Longevity List

Hair care is getting the long-view treatment once reserved for skin. Kérastase's Chronologiste collection puts scalp health at the center of that shift, treating vitality as the foundation for hair that holds up over years, not just one event. It's a quieter kind of investment than a cut or color — the maintenance nobody sees on the red carpet, but that makes the rest of it possible.
