Noun: Vitamins that promote hair growth are essential nutrients that aid in the development and maintenance of healthy hair. An example is biotin, a B vitamin that helps strengthen hair follicles and prevent breakage.
These vitamins play a crucial role in nourishing the scalp, stimulating hair follicles, and preventing hair loss. Historically, the discovery of vitamin B7 (biotin) in the 1930s marked a significant breakthrough in understanding the role of vitamins in hair growth.
