The Cathy Doll Hair Line Cushion is an innovative root touch-up pen that instantly fills in sparse hairline gaps for a visually fuller and thicker look. Formulated with a creamy, highly pigmented shadow powder, it features an easy-to-use, rounded cushion-tip applicator that allows for controlled and highly precise dabbing without messy fallout. The long-lasting, water-resistant formula ensures your hairline remains perfectly defined and smudge-free through sweat, rain, or humidity. It blends seamlessly into the hair without forming harsh lines, making it an excellent daily companion for establishing clean hair borders and hiding grey growth between dye cycles.
