One of the theories why hair turns gray is that with age the body stops producing melanin and the hair becomes gray, silver or white.
Here are some interesting facts about gray hair:
* The appearance of the first gray hairs is determined by genetics, but also by age. Gray hair is the result of aging and its texture changes with age, as does the texture of the skin. Experts call these changes rule 50-50-50. Half of the world’s population under the age of 50 has about 50 percent gray hair.
* Whites turn gray faster than any other race. After them, the yellow race turns gray the fastest, followed by the black. Experts have not yet established why.
* In addition to genetics and age, hair turns gray due to stress. Constant exposure to stress can damage DNA, affecting the cells responsible for pigment production. This is most evident during illness, when patients may “turn white” overnight. Also, due to the stress suffered after chemotherapy, hair can grow in a different color.
* Lifestyle affects the appearance of gray hair, especially due to smoking. Toxic chemicals from smoke damage the DNA of the hair, cause the accumulation of harmful free radicals and affect the production of pigments. In addition to cigarettes, a lack of vitamin B12 and honey can accelerate the appearance of gray hair. That is why the diet should be enriched with carrots and dark chocolate.
* Hair grows for an average of three years and then falls out to make room for a new one. With age, the new hairs that replace the old ones are already gray. The hair does not turn gray, but is white from the root. Each time the hair is renewed, the cells that make up the pigment change and this process becomes more difficult with age, so they just stay white.
