The product: Sally Hansen Color Therapy Nail Polish ($9, available in December)

Why you need it: This genius argan-oil-infused formula is designed to be used without a base coat, so the nourishing properties of the lacquer can directly penetrate the nail. It also contains acai and evening primrose oil, both rich in fatty acids that strengthen and condition weak nails.
