GrandeREPAIR Leave-In Lash Conditioner protects, strengthens, and softens lashes. This invisible, leave-in formula reduces brittleness and breakage, fortifying lashes against daily loss and environmental toxins. Infused with Widelash, a biotin peptide, along with botanical and nourishing oil blends, it provides intense moisture. This conditioner can be worn under mascara during the day or alone for overnight conditioning, and is ideal for post-extension lash care.
