Color Club Pro-Renew Nail Hardener

Renew your nails and kiss soft, breakage-prone nails goodbye! Formulated to resurface brittle nails and increase hardness in as little as one week. This 3-in-1 treatment applies as a base coat, top coat, and hardening treatment. Alpha hydroxy acid is included to resurface and renew damaged nails while a patented twofold plasticizer promotes wear and shine extension. Nails are up to 87% harder after just one week. Directions: Use as a hardening treatment by applying to bare nails twice a week (remove before new application), or as a top and base coat with your favorite nail polish.
