Hair consists mainly of keratin. Keratin Is composed of protein molecules, which are connected to sulfur. Problems with hair arise when the keratin level in the body is low, or when sulfur bridges are damaged. Substances that are necessary for the build-up of keratin are Vitamin C, biotin, silica, organically bound selenium and zinc, and sulfur amino acids such as methionin.
All above mentioned nutrients are in HairVitals.
