That's why you can turn white prematurely: gray hair and a lack of certain vitamins ...

Vitamin deficiencies and hypothyroidism may be key causes of premature graying of hair.

Evidence suggests that signs of aging, such as gray hair, can in some cases be delayed or even reversible.

The length and appearance of skin and hair are important for a person's self-esteem. As the body ages, these features are the first to show signs of aging. There is evidence that genetics is the most important factor in determining the appearance of gray hair, but research suggests that nutritional deficiencies may also play a role.

A lack of iron and vitamins D and B can make hair gray.

Graying hair is a sign of autoimmune diseases and other lifestyle factors such as stress and smoking.

Research has also shown the role of environmental factors such as exposure to ultraviolet light, climate, micronutrients and nutrient deficiencies in hair graying.

According to the Express “While the main causes of premature graying of hair are believed to be genetic, several environmental factors also play an important role. Micronutrient deficiencies such as vitamin B12, vitamin D3, and calcium may also be associated with premature graying of hair.”

While the researchers found that graying often coincided with low vitamin D levels, they were unable to prove a causal relationship between the two.

Autoimmune disorders associated with premature graying of hair include vitiligo and pernicious anemia, which is associated with B12 and iron deficiencies.

The involvement of anemia in hair graying is explained by the role of iron in blood cells. Since iron is responsible for transporting oxygen throughout the body, it is thought that it may also play a key role in prolonging the production of hair pigment.
