Working as a stylist in 1950s Paris, Rene Furterer observed an epidemic of dry, damaged, bleached-out hair. (We had Marilyn Monroe’s iconic blond bob to thank for that.) He quickly realized that nourishing both the scalp and the hair was crucial to maintaining a healthy appearance. Soon after, he founded his namesake haircare line. Based around natural essential oils, these products combine plant-based nutrients with the latest pharmaceutical ingredients to create formulas that build strong, shiny, covetable hair from the roots on up.
