Tag: Hair repigmentation

By age 50, about half of the population has at least 50% grey hair. While this process is natural and genetically determined for most, many wonder if supplements can halt or even reverse it. Recent studies have explored the link between nutritional deficiencies and premature graying, offering some hope but not a guaranteed cure.

According to research, vitamin B12 deficiency is considered one of the most common causes of premature graying in younger adults. While gray hair is typically associated with aging, a nutritional shortfall can sometimes interrupt the production of melanin, the pigment responsible for hair color.

According to a 2022 study in the *International Journal of Dermatology*, individuals with premature graying often have significantly lower levels of vitamin B12. This finding has led many to question: does vitamin B12 darken hair? The answer is nuanced, depending on the underlying cause of your hair's depigmentation.
