What causes hair bleaching? Important facts about hair?

There is a clear link between white hair and stress, and it is generally believed that hair bleaching may not happen overnight. Still, there is a scientific explanation that stress kills hair pigment-producing stem cells because they stop staining hair follicles.

Experts say genetic predisposition, environmental factors, and aging can cause gray hair. The human body has millions of hair follicles located on the skin and creates hair and color that, over time, these hair follicles can lose the ability to produce color that leads to hair bleaching.

This happens when the body stops producing melanin, and as you age, the cells in your hair follicles secrete a small amount of hydrogen peroxide (a metabolic byproduct). Usually, an enzyme called catalase, which breaks it down. It is in water and oxygen. The level of catalase decreases with age, which causes hydrogen peroxide in the hair follicles to form melanocyte cells or pigment-producing cells that damage the hair and deprive them of Destroys.

Every person’s body produces melanin for a certain period, so there is no specific time for hair to turn white, and one person may turn white at age 25 because they do not produce melanin, and another person has black hair at age 50. 10-20% of their paint production capacity every ten years.

Does hair turn white overnight?

Marie Antoinette syndrome or sudden graying of hair gives a clearer answer to this question. Marie Antoinette Syndrome is a rare and special syndrome in which a person suddenly turns white due to severe anxiety and stress.

This syndrome is not a common disorder, and in fact, only 0.2% of the general population have experienced Marie Antoinette syndrome.

Does stress cause hair to turn white?

One of these external factors is hair bleaching stress; studies show that hair pigments may be lost during stress. In addition, stress can cause conditions called telogen, which causes hair loss to be about three times faster than normal, and by the time people reach middle age, hair regrowth will turn white instead of black.

Oxidative stress in the body is associated with hair bleaching; oxidative stress causes the body to become unbalanced when free radicals damage cells. When there are not enough antioxidants to neutralize the damaging effects of free radicals, it can lead to aging. And diseases such as spots.

Instead of stress, you can focus on other factors that cause hair bleaching and a lack of nutrients such as vitamin B12, folate, copper, iron, and calcium. Smoking is one of the reasons for hair bleaching. It causes oxidative stress and diet. Foods become high in sugar.

A gene called IRF4 (an interferon regulator) has been discovered that causes hair to turn white, but the IRF4 gene makes up about 30% of white hair, and environmental factors, including stress, make up the rest.

The link between infection or stress and gray hair

There is a link between the immune response genes and those that regulate skin and hair color, which means that a severe infection can accelerate the hair whitening process.

Not surprisingly, infections that severely affect the body are stressful. The body must adjust to adaptive mechanisms that allow it to survive and not give in, and if it adapts properly, it will overcome stress.

Misconceptions about hair bleaching:

Do other hairs turn white by plucking white hair?

Hair bleaching is genetic and inherited. Research has shown that smoking can cause premature aging and premature graying of hair, so this belief is partly true.

Can white hair return to its previous color?

White hair does not normally return to its previous color, and white hair cannot be restored to its previous color without medication, a special diet, or hair dye, so this belief is wrong.
