Biotin is a water-soluble B-complex vitamin, also known as vitamin B7. The name originates from the Greek word “biotos,” which means “life” or “sustenance.” It is an essential nutrient, meaning the body cannot produce it in sufficient quantities on its own—you need to get it from biotin rich foods or supplements. https://www.vcareproducts.com/blog/biotin-for-hair-growth-secret-to-stronger-thicker-hair
