Thus, some specialists speak of vitamin B12 as a vitamin with influence on the appearance of premature graying of hair. And this would be related to episodes of stress.

In addition, experts also link the appearance of gray hair with autoimmune diseases such as hyperthyroidism, genetic basis or premature aging.

Generally, there is a very powerful genetic component that drives the appearance of gray hair. Gray hair usually appears as we age, although there are some people who begin to develop this fact during adolescence or youth.

In a more scientific way, experts also point out that oxidative stress is a risk factor for the appearance of gray hair. That is, if there is damage to the cells responsible for the production of melanin (melanocytes), the appearance of gray hair is caused.

Thus, the lack of vitamin B12 or thyroid alterations can also contribute to the decrease in melanin synthesis in the hair follicle and favor the early appearance of gray hair. Therefore, vitamin B12 deficiency could be a risk factor for gray hair.

On the other hand, the mentioned oxidative stress can also be generated by emotional stress, alcohol consumption, pollution, ultraviolet radiation, unhealthy diet, sedentary life or tobacco consumption.
