Why are men more likely to go bald than women?

In addition to hair loss caused by certain diseases or drug factors, the main cause of baldness is the excessive secretion of male hormones in the body, and the sebaceous glands are mainly controlled by male hormones. If the secretion of male hormones is too vigorous, the back and chest of the human body, especially the face and the top of the head, will secrete too much oil. When the pores on the top of the head are clogged with oil, the nutrients** of the hair will be impaired, which will eventually lead to gradual hair loss and finally baldness.

This is the reason why baldness is rarely visited by women, because they lack male hormones. Sadly, hair loss in men can also occur at the same time as forehead and crown hair loss. Eventually, only the remaining hair on the occipital region and both temporal areas remains, thus forming a 'Mediterranean' shape.

Why doesn't the hair fall out on the occipital and temporal areas? This is mainly due to the fact that the scalp in the forehead and top of the head is more "expressed" in androgen receptors and 5-reductase, while the occipital scalp has fewer or almost no "expression" of androgen receptors, she explains. As a result, occipital hair follicles in patients with androgenetic alopecia are almost unaffected by androgens.

In medicine, baldness is called "androgenetic alopecia", also known as "male pattern baldness". The main reason for this is that in people with a genetic predisposition, androgens (mainly testosterone) in the body affect the hair follicles in the head, causing the hair follicles to shrink gradually. When testosterone is catalyzed into dihydrotestosterone by an enzyme called "5-reductase", it can bind to androgen receptors by more than 5 times, resulting in massive hair loss.

As we all know, testosterone is the main sex hormone in men, and women usually have very little testosterone in their bodies. This is also the reason why baldness is usually more common in men, Liao said. Generally speaking, "androgenetic alopecia" in women is relatively rare, and when it does, it is generally mild, and alopecia totalis at the top rarely.

Because men produce more androgens, androgens lead to male and female, men's hair is an old shell, and hair suddenly appears around in the middle, which is caused by typical androgen androgenism.

Because there are several causes of baldness, excessive secretion of male hormones, mental stress, smoking, drinking, staying up late and other bad habits, as well as genetic factors.

These are all problems that men are more likely to have, including genetics that men are more likely to have than women, so men are more bald than women.

Men have more baldness than women, this is mainly due to the fact that male sebaceous gland secretion is more vigorous than that of women, and sebaceous gland is an important factor that inhibits normal hair growth and damages the scalp.

Because baldness is caused by high levels of male hormones, and at the same time, men have relatively high levels of male hormones, so they are prone to hair loss. And modern men are more stressed, leading to hair loss. Excessive stress, frequent socializing, and excessive drinking and smoking.

First of all, let's understand the causes of hair loss, most people's hair loss, especially large-scale hair loss, is related to male hormones, and the level of male hormones in men is much higher than that in women. Androgen-derived alopecia is also known as seborrheic alopecia, the symptoms of this type of alopecia are that the hair becomes fine and soft, sparse, but the pattern of male and female hair loss is not the same, the initial stage of male seborrheic alopecia is from both sides of the forehead, the hair is gradually thin and thin, forming M-shaped alopecia, and gradually the forehead hair gradually retreats back, and then the hair on the top of the head begins to fall out, until the hair on the top of the head falls off and the scalp is exposed. In women, seborrheic alopecia is mostly Christmas tree-like, showing diffuse hair loss.

Male baldness is more abundant in women because the male body secretes more male hormones, and androgens have a great impact on hair follicles.

The main reason is that the secretion of sebaceous glands in men is more vigorous than in women, and the sebaceous glands are an important factor that inhibits the normal growth of hair and damages the scalp, and most male baldness is related to this. The damage to these sebaceous glands is often irreversible, so as we age, the symptoms of hair loss and hair loss become more pronounced and severe.

Men have more baldness than women because of the low amount of male hormones secreted in women's bodies. The second is the problem of heredity, through the study of the heredity of male baldness, it was found that baldness is inherited with sex chromosomes, and baldness is generally inherited from generation to generation; The most important point is that men are more stressed than women in life and work, which will also accelerate the occurrence of baldness.

The main problem is that men work hard, the pressure is particularly high, and on the other hand, men's physique itself is more prone to this state.

It is human nature to love beauty, and everyone hopes that they can be beautiful and fashionable every day. But if you imagine that you don't have black and shiny hair, you are a bald scene. Do you know why men are more likely to be bald than women?

What is the reason, I believe many friends do not know much, let me answer your doubts below.

Some people start to lose their hair early when they are young adults in their 20s and 35s. This type of hair loss often falls out from the front of the hairline, causing the hairline to gradually extend backwards, or even the hair to fall out completely, which is called "premature baldness". It has been found that the disease is more common in men and less common in women.

It stands to reason that scientists have found out that the pathogenic gene of this disease is located on chromosome 3, which is an autosomal dominant disease, and the number of male and female patients should be basically equal, but why is there such an obvious difference between men and women? It turns out that this is a special genetic phenomenon - dependent inheritance, although the disease-causing gene is located on the autosome, it is affected by sex. In fact, about 80% of patients with proteus baldness are men and only 20% are women.

This is because the premature alopecia gene cannot cause the onset of the disease by itself, and its effect is also affected by androgens, and the androgens in the male body have become the "**" of this gene, so another name for the disease is called "androgenetic alopecia".

In addition to sexual inheritance such as premature alopecia, there are also diseases caused by disease-causing genes located on autosomes, which are also affected by sex. The causative gene for "male precocious puberty" is located on chromosome 2, which is a sex-limited genetic disorder in which the role of the causative gene is limited to one sex. Puberty begins under the age of 9 (and some even at the age of 2 or 3).

The disease is confined to boys, and girls can pass on the dominant gene to their sons, causing precocious puberty.

There is also a genetic disease that is affected by the disease-causing gene** on the father or the mother, as if the disease-causing gene is marked with the seal of "father" or "mother", which is called genetic imprint. For example, symptoms of Huntington's disease generally appear by the time people are 35 to 45 years old. Studies have shown that if the gene that causes Huntington's disease comes from the mother, the age of onset of the disease is similar to that of the mother; If it comes from a father, the age of onset of the child is earlier than the father's age of onset and the disease is severe.

In some families, the age of onset of the child is even advanced to about 20 years. However, the transmission of this paternal effect is limited to paternal origin: the age of onset of onset is not earlier in the offspring of females with premature onset; Male offspring with premature onset will have earlier onset age in their children.

For example, American folk artist Woody has a gene for Huntington's disease that comes from his mother. He became ill around the age of 37 and died at the age of 55. He passed on the gene to his two daughters, both of whom became ill at the age of 24 and died at the age of 41.

1 Needless to say, there are much more male hormones in the male body than in the female body, and there are basically no male hormones in the female body, and the male hormones are able to combine with the amount of dihydrotestosterone, which causes the hair follicles to shrink, so that the growth cycle of the hair follicles becomes shorter and shorter, and the hair grows thinner and thinner, and eventually, the hair is so thin that it is invisible to the naked eye or disappears completely. Eventually, baldness was caused.

2. Baldness is also a manifestation of social status.

Although hair has a protective effect, the social value of baldness may outweigh this protective effect, so it has been passed down in the course of evolution. Because hair is also a social symbol, it can influence people's impressions. Subconsciously, balding men tend to be more mature, aged, and more experienced and wise.

The same applies to our "close relatives" chimpanzees and gorillas.

3. Genetic mechanisms make men more susceptible to hair loss. From the perspective of genetics, the gene of male hair loss is dominantly inherited, and female hair loss is recessive, and most of them show diffuse hair loss, and there are few phenomena such as baldness.

Specifically: the human baldness gene, dominant A controls not baldness, recessive A controls baldness, AA is not bald in both men and women, and AA is bald in both men and women, but the difference is that when AA is heterozygous, males are bald, and females are not bald, so there are more bald males than females.

4. Temporary hair loss may occur due to mental stress, staying up late, smoking, drinking, kidney deficiency and other reasons.

Men who use computers for a long time every day are prone to hair loss; Men with poor sleep quality due to long-term stress, anxiety, and fatigue can lead to hair loss, and men who often dye their hair and perm their hair are prone to hair loss, etc. If you don't pay attention to maintenance in life, baldness may come.
