Leonor Greyl Huile de Leonor Greyl
The house's original product, sold since 1968 as a pre-shampoo treatment: a blend of plant oils brushed through dry lengths, left on for an hour or overnight, then washed out. It protects hair from the shampoo itself, and from sun and pool water. It is the oldest idea on this page and still one of the best.
