There is no scientific evidence to suggest that monosodium glutamate (MSG) causes gray hair. Gray hair is primarily a result of aging and genetics, as the production of melanin decreases over time. While some studies have explored various dietary impacts on hair health, MSG has not been directly linked to graying hair. Therefore, it is not considered a factor in the process of hair turning gray.
