Nowadays, many people find that they are not old yet, why do they start to have gray hair? It is obvious that he is only in his early 30s, and his hair has already begun to turn gray. Is it the rhythm of aging before aging?
Why do I have gray hair?
The causes of gray hair are more complicated. Generally speaking, it can be roughly divided into two types, congenital and acquired.
Congenital gray hair generally has a family history, and localized gray hair is relatively common, mostly in the anterior hairline. It is more common in children and adolescents.
Of course, when a person with albinism is born, all hair is white
Acquired gray hair is mostly caused by chronic stress or lack of nutrition.
For example, gray hair tends to grow when a person suffers from a major trauma, such as excessive stress, anxiety, or greater stimulation.
For example, the lack of some vitamins, trace elements and other nutrients on the body will lead to a decrease in hair pigment and an increased chance of gray hair.
At the same time, some diseases such as hyperthyroidism, tuberculosis, vitiligo, etc. often appear white hair at first. is white.
What should I do about premature gray hair?
In fact, some people think that eating more sesame seeds and black beans can make gray hair black.
But this doesn’t really make much sense.
Grey hair is actually difficult to solve the problem by eating. If the white hair is caused by nutritional problems, then it needs to be improved by eating. After correcting nutritional deficiencies, gray hair may improve, but it is actually difficult to restore gray hair that is already there.
Foods such as black sesame and black beans are rich in nutrients and trace elements. If the problem is due to nutritional deficiencies, it may be improved.
However, the main source of melanin in hair is melanocytes, which use tyrosine in the body to convert it into melanin.
Grey hair from other causes is not much use by eating
For those who have gray hair due to tension and stress, they need to maintain a happy mood.
The human body is in a healthy state, and the various functions of the body can be maintained at a relatively good level. In this way, the hair follicles on the scalp will be healthy, and the gray hair will naturally decrease.
And for some congenital white hair, hereditary white hair, senile white hair, most of which are determined by genes and heredity, it is difficult to pass Changed the day after tomorrow.
Will my grey hair grow more and more?
Folklore: Pulling out one white hair produces seven white hairs. Is this true?
False! of!
First of all, it is necessary to understand that the hair follicles on the head actually exist in the embryonic period of human development, but not all hair follicles can grow hair correspondingly, but the growth of hairThere are still certain rules.
According to relevant statistics, a normal person will grow about 100,000 hairs in a lifetime, and as people get older, there will be fewer and fewer active hair follicles, and hair will also grow. It will become less and less, which is why the hair of the elderly becomes thinner.
When gray hair grows, pulling it out will not affect the rest of the hair.
However, although pulling hair all the time will not affect the secretion of other hair follicle pigments, it may cause folliculitis and lead to more baldness.
