There are often scenes in movies and TV series: a person turns his head back overnight after suffering a huge trauma.
Modern medicine has proved, mental pressure is one of the important inducement that brings about white hair.
Recently, researchers at Columbia University, in collaboration with the Miller School of Medicine at the University of Miami, found evidence that hair turns white under pressure. In addition, the research team also found that once the stress event is over, the gray hair associated with the stress will return to its original color.
Columbia University: Stressful gray hair is reversible
This study analyzed the role of melanin and certain proteins in giving hair color. The research team collected 400 hair samples and used a new imaging technique to detect the pigment levels in different parts of the hair.
In addition, the research team has also developed a method to quantitatively describe natural graying events and their proteomic characteristics related to individual human hair, thereby generating a quantifiable physical time scale of aging.
In this way, the researchers found that in healthy young people, gray hair will naturally restore pigmentation within a few days to a few weeks, regardless of gender, race, age, and body area, which indicates that human hair turns white. It is naturally reversible.
Researchers believe that some hairs are gray at the top instead of the roots, but the hair grows from the roots. Therefore, this indicates that the hair turned white at a certain point in time,and then at a later point in time the original color was restored.
Because the growth rate of hair is constant, researchers can calculate when a person’s hair starts to turn white and when the hair returns to its natural color. They asked the volunteers if they had experienced a stressful event when their hair turned white, and found a matching answer.
After adjusting for multivariate factors, the researchers said that these findings illustrate the reversibility of human hair graying. Stress does cause hair to turn gray. Eliminating the stress factor can restore hair to its original color. At the same time, the researchers emphasized that this reversal seems to apply only to hair that has turned white due to stress, and only shortly after the hair turns white.
In 2019, the team of luppol,an associate professor at Northwestern University’s Feinberg School of Medicine, also published related research. They believe that stress is related to many skin and hair problems. After a stressful event, the regrowth of hair may appear a different color.
4 types of people should be careful the white hair comes to you
Graying of hair is an inevitable phenomenon in the aging process. Generally speaking, Asians begin to develop gray hair at the age of 30-40, a little later than Caucasians, and Africans the latest, and this is determined by genes.
Genes can plan when we have gray hair. Generally speaking, the younger the parents have gray hair, the earlier their children have gray hair.
Anthony, a professor at the Stanford University School of Medicine in the United States, has a famous “50-50-50 rule”, that is, 50% of people in the crowd have 50% of their hair turned gray when they are 50 years old.
In addition to people with a family history of gray hair, people who suffer from certain diseases, malnutrition, and frequent smokers are also more likely to grow gray hair.
Diseases: such as hyperthyroidism, ulcerative colitis, nephropathy, vitiligo, etc., may cause varying degrees of gray hair.
Smoking: The US “Good Butler” website stated that smoking puts pressure on the skin and hair. Low vitamin B12 content in the body has a lot to do with the loss of hair pigment.
Nutrition: When the body lacks certain trace elements, gray hair will increase. Previous studies have shown that malnutrition causes a decrease in hair pigmentation and an increase in gray hair.
6 ways to make hair gray slowly
No one wants gray hair at a young age. If you want to make gray hair come later, you might as well try the following tips.
Decompression in time
For gray hair that appears due to tension and mental stress, it is necessary to control emotions in time and reduce pressure reasonably.
Exercise is an important way to regulate emotions. When stress is high, it is even more important to adhere to regular exercise. Aerobic exercises such as swimming, running, brisk walking, and soothing exercises such as yoga have been proven to help reduce anxiety.
Avoid veganism
Hair is closely related to trace elements in the body. The cells in hair follicles are the fastest growing cells in the human body, and their growth must be adequately nourished.
It is recommended to eat more protein-rich “hair care” foods such as fish, beans, green leafy vegetables, animal liver, walnuts, sesame, etc. to help strengthen hair.
scalp massage
Frequently massage the scalp with a comb or fingers to help promote blood circulation and provide adequate blood supply to the fragile hair follicles.
Reduce hot dyeing
Do not use inferior shampoos, reduce perm and dye, reduce hair damage and protect hair quality. Under normal circumstances, the interval between two perms should not be less than half a year.
For those who have gray hair, more attention should be paid to reducing the number of perm dyeing.
Adjust lifestyle
For people with gray hair, the most important thing to do is to adjust their lifestyle. Do not stay up late, do not overeating, do not smoke, drink alcohol, and ensure adequate sleep.
Pay attention to sun protection.
White hair is more likely to appear at the hairline and the edge of the hairstyle, and these parts are prone to long-term UV stimulation.
To prevent gray hair, take care to protect the scalp from sun. Wearing a hat and playing a parasol are all good choices when going out.
White hair is the mark of time, don’t worry about it. Accept it bravely, neatly combed, and it can be beautiful and handsome.
