Gliss Night Elixir

A leave-in overnight hair oil from Schwarzkopf Professional, Gliss Night Elixir delivers a silky, non-greasy finish that nourishes dry or damaged hair while you sleep. Lightweight and easily absorbed, it suits frizz-prone and heat-styled hair. Often marketed as a restorative nightly treatment, some formulations are fragrance-free or aimed at color-treated hair.
