Rosemary Serum

A lightweight, leave-in serum designed for daily use to support fuller, healthier-looking hair. Formulated with a high concentration of rosemary-derived ingredients, a peptide complex, plant proteins, and ceramides, it absorbs quickly with no residue and helps maintain scalp and hair balance. Dries clear, feels weightless, and has a natural rosemary scent with no added fragrance.
