Hair and Nails Formulation is composed of Chinese herbs that have been used for a thousand years by Chinese royalty to promote the growth of beautiful, healthy, strong hair and nails. The herbs are nourishing to the blood and thus provide needed nutrients to the hair and nails. The herbs also improve blood circulation, and particularly the microcirculation that supplies the hair and nails. The formula helps remove toxins and reduce stagnation and helps regulate hormonal functions. Hair and Nails Formulation has strong antioxidant activity, and is considered an excellent Yin Jing tonic that may be used as a basic formula in a personal wellness program.
