Here's something everyone needs, but might not know they need — a ultra-nourishing cuticle oil from Mazz Hanna, celebrity manicurist and crystal healer. It's not only made with a blend of botanical and essential oils to hydrate your nails and cuticles, but it also features an amethyst roller ball, which she says will help fight the urge to pick or bite your nails, because the stone's "healing powers" can help you break bad habits."
