The Promille Karte Hair Repair Mascara is a styling product designed to tame unruly hair, such as flyaways and messy bangs, without making the hair stiff. It uses a moisturizing “Moist Repair Gel” formula with ingredients like feather keratin, gold sesamin oil, and baobab oil to add shine and moisture while repairing damage. It is used for finishing styling to keep hair in place and can be adjusted for different looks, from neat to more natural styles.
