While vitamin B is essential for overall health, excessive intake of certain types can lead to various health concerns, including hair loss. Vitamin B is a water-soluble group of vitamins that plays a crucial role in energy metabolism, cell growth, and the functioning of the nervous system.
Particularly, high levels of biotin (vitamin B7) have been linked to hair loss. Biotin is involved in the production of keratin, a protein that forms the structure of hair. While biotin deficiency can cause hair loss, excessive intake can disrupt the normal hair growth cycle, leading to hair thinning and breakage.
