Hair graying or bleaching is when the hair loses its natural color as the age progresses. This process normally starts after the 30s and 40s. Hair graying is as natural as we have hair, but most people are concerned about it due to society’s attitude to aging. A number of studies have been conducted on the causes and prevention of hair graying.
What Gives The Hair Its Natural Color?
The substance that gives the hair its natural color is melanin, which is the brown / black or yellow / red pigment that determines the color of the skin and eyes. Melanin is also responsible for the color of our hair. The amount and combination of melanin is a factor that determines the color of the hair.
Why Hair Goes White?
Why the hair turns gray has been the subject of many studies. Gray hair also contains a small amount of melanin. There is no melanin in white hair. One reason for this is the gradual decrease in the number of stem cells that develop into melanin-producing cells. The cells may be aging and damaged, or they may have lost the support systems that would enable them to function properly. Genetics are also an important factor in graying hair because genes support the control of melanin production.
How To Prevent Gray Hair?
Some supplements can be taken to make your hair thicker or to prevent hair loss, but unfortunately, we cannot stop hair whitening. Experiments on mice have shown that three genes can help keep the number of melanin-producing cells constant. By manipulating genes, the researchers prevented or reduced the number of gray feathers on mice. However, there is no product used in this research on the market.
Does Stress Whiten Hair ?
The answer to the question of whether it is possible to graze due to stress: maybe. Scientists conducting research on gray hair have found evidence of harmful chemicals (free radicals) caused by stress, smoking, inflammation or radiation, and pointed out that these free radicals can be harmful to pigment-producing melanocyte stem cells.
Does Smoking Whiten Hair ?
It is thought that there is a relationship between smoking and graying of hair. A study conducted in 2013 showed that smokers had gray hair three years earlier than non-smokers. Scientists believe that smoking causes chemical changes that damage melanin-producing cells in the body.
