Why Does Hair Turn Gray

Why does hair turn gray? Hair loses coloring pigment as a result of severe psychological shocks, chronic stress, health problems due to alcohol abuse, taking certain medications, after surgical anesthesia. Irregularities in the functioning of internal organs, for example, thyroid gland dysfunction, and an unbalanced diet, which causes the body to begin to experience a deficiency of many important trace elements, such as copper and zinc, also cause gray hair. A genetic predisposition, which is often called the cause of platinum hair, cannot be ruled out.

Gray hair and stress hormone

Gray hair can appear from stress or a strong emotional shock. But until recently, the mechanism by which this occurs was not known.

Researchers first tested cortisol, or the “stress hormone,” which is released into the blood when a hazard mechanism is triggered in the body.
This feature allows a person to mobilize resources to avoid danger. The long-term presence of cortisol triggers many negative reactions, such as chronic stress

The nerve endings of the sympathetic nervous system are scattered throughout the body, including the hair follicles. Substances released during the reaction to stress – in particular, the neurotransmitter norepinephrine – activate pigment-forming stem cells prematurely, gradually depleting the “reserves” of hair color.

Can gray hair be restored?

If you put your nerves in order and get rid of chronic stress, will your hair stop turning gray?
Unfortunately, this process from stress is irreversible. Those hairs that have already lost their natural color will remain gray.

Where does gray hair come from?

the effect of stress on the body

Stress is not the only or even the main cause of gray hair. Gray from stress appears with a combination of factors. The main factor is genetics.

Melanocytes gradually disappear with aging as a result of the oxidative process, since each hair initially has a certain number of these cells.

Oxidation occurs due to an imbalance between free radicals and antioxidants. The former triggers the mechanism of cell death and damage to DNA sites, while the latter inhibits this process. Until a certain moment, while we are young, the body successfully resists oxidative stress by producing antioxidants. But with age, this ability decreases.

Other factors that can cause gray hair:

  • protein deficiency;
  • lack of copper and iron;
  • vitamin B12 deficiency.

How to prevent it?

How to prevent it

Oxidative stress cannot be stopped, but it is quite possible to slow it down. It is possible to restrain premature graying by normalizing nutrition. You need to provide your diet with foods with omega-3 fatty acids:

  • walnut;
  • seafood and oily fish;
  • linseed oil;
  • seaweed;
  • avocado.

To prevent premature aging of hair, avoid ultraviolet radiation. Visit tanning beds less and cover your head with a hat on vacation in hot countries
