René Furterer CURBICIA Normalizing Lightness Shampoo is a purifying shampoo designed for oily hair and scalps prone to excess sebum production. It gently cleanses and removes excess oil, leaving the hair feeling fresh, clean, and lightweight for longer. Its formula combines Curbicia extract, derived from pumpkin seeds, with essential oils of clove, thyme, rosemary, and orange. These ingredients help purify the scalp and regulate sebum production, allowing users to space out shampooing.
