If you look at gray hair, you may find that it turns black as you go to the root.I can understand if black hair is gray, but it's a bit strange that gray hair is black.
Actually,This state of "black hair from the middle" is the state that gray hair has been improved.Therefore, by knowing how this condition was born, you can reduce the gray hairs that are growing now.
So this timeThe reason why gray hair is improved from the reason why gray hair growsI tried to consider!If you are thinking about not only preventing gray hair but also improving it, please refer to it.
1. Why do gray hairs grow?
Before approaching the mystery of "white hair turns black from the middle", firstwhy do you have white hairI would like to explain the basic mechanism of
Many Japanese people have dark hair since they are born, but actually, the color of their hair is actually transparent.The reflection of transparent hair makes it appear as gray hair.in short,Gray hair is not black hair that died and turned white, but it returned to the original transparent hair.It will be said.
why hair turns black
The hair looks black because the black pigment melanin pigment is incorporated into the cortex inside the cuticle.After the melanin pigment is produced by the melanocytes in the hair root, it is sent to the hair matrix cells that create the hair, and the hair is colored.
If the melanocytes are working normally, the melanin pigment will be taken in properly and black hair will grow, but if the melanocyte function is reduced, the production and fixation of the melanin pigment will be delayed and gray hair will grow. will come.
In other words, The number one reason why gray hair grows is thought to be a decrease in the function of melanocytes.It is
2. What is the cause of black hair even though it was white hair?
So far, we have talked about the reasons why gray hairs grow, but the state in which gray hairs turn black as they approach the roots is a state in which the function of melanocytes has been improved.
Then,How did the function of melanocytes come to be improved?There are four possible causes:
Cause ① Malnutrition improved
The first thing that comes to mind is that the disordered eating habits have been improved and the malnutrition has been resolved.
In order to fix the melanin pigment in the hair, it is necessary to ingest minerals, vitamins, proteins, etc. in a well-balanced manner.
However, due to an unbalanced diet, the ingredients for hair and black pigments are insufficient, blood volume is reduced, and blood circulation is poor.As a result, healthy black hair cannot be produced, and the hair turns gray.
In other words, By improving the nutritional status, nutrition began to spread to the parts that had turned gray.It is thought that this is the reason why black hair was revived.
Cause ② Fatigue and stress are less likely to accumulate
Gray hairs may also improve when fatigue and stress that tend to accumulate are eliminated.
When stress and fatigue accumulate, the sympathetic nervous system becomes dominant and the body is always in a state of tension.As a result, the blood vessels are narrowed and the blood circulation is poor, and the nutrients necessary to make hair on the scalp are always lacking. You can also relax.
By reducing stress as much as possible and making a habit of creating time when the parasympathetic nerves are dominant, you can prevent fatigue and stress from accumulating too much, which will lead to the improvement of gray hairs..Find your own way to relieve stress and use it to improve your gray hairs.
Cause ③ Poor blood circulation improved
As I mentioned earlier, poor blood circulation can affect the scalp environment and cause gray hairs.
Eliminating malnutrition and stress is important to improve blood circulation, but moving muscles is also effective in improving poor blood circulation.
In order to move the muscles, it is effective not only to exercise such as stretching, aerobic exercise, and muscle training, but also to stimulate the muscles with massage.you know.
Massage and exercise are good not only for gray hair but also for the body, so let's work on it within a reasonable range.
Cause ④ Thyroid function recovered
If the roots of the hair are black and the tips are gray, most of the cases are that the gray hair has been improved by improving the above lifestyle habits..
However, inEven if the decline in thyroid function is improved and gray hair turns blackI have.Decreased thyroid function can lead to hormonal imbalance and disturbance of the autonomic nervous system, and cholesterol levels can rise, making it easier to produce active oxygen.
Women are especially prone to this thyroid dysfunction.It is known that 20 in 1 women develop abnormalities after giving birth, and thyroid function tends to decrease even after menopause.
about the thyroidIt is difficult to recover yourself, so it is important to consult a doctor and take appropriate care.It will be.
Restoring thyroid function will make your daily life easier than solving the problem of gray hair. If symptoms such as “easily tired”, “swelling is severe”, and “no motivation” are severe, thyroid function may have decreased, so it is recommended to see a doctor.
3. Improve gray hair and regain healthy black hair
A sign that the gray hair has improved from the middle is that the gray hair is darker as it goes to the root.
By activating the action of melanocytes that produce black hair, it is possible to turn gray hair into black hair.I want to understand the cause of gray hair firmly and remove it from my life as much as possible.
Of course, it is natural that gray hair increases with age.Don't give up saying "I can't help it" and review your lifestyle habits.You may be able to get back to black hair by taking care of it without giving up.
