A hair, skin, and nails supplement is a dietary product formulated to promote the health and well-being of hair, skin, and nails. One example is a multivitamin containing biotin, which supports hair growth and health.
These supplements are popular because they can provide essential nutrients that may be lacking in one's diet. They offer benefits such as improved hair growth, stronger nails, and healthier skin. Historically, the use of supplements for hair, skin, and nails can be traced back to ancient times, with records of using herbal remedies for these purposes.
