Hair and nails vitamins, a supplement category, refer to nutritional formulations designed to support the health of hair and nails. One common example is Viviscal, a supplement containing marine collagen complex, biotin, and other nutrients that promote hair growth and nail strength.
These vitamins are important because hair and nails are composed primarily of keratin, a protein that requires specific nutrients for optimal growth and appearance. Benefits include improved hair growth, reduced hair breakage, stronger nails, and a healthier appearance overall. Historically, the recognition of the link between nutrition and hair and nail health led to the development of targeted nutritional supplements.
