Is hair loss hereditary? What are the chances of inheriting hair loss?

Experts say that there is some truth in the heritability of baldness, and it is dominantly inherited in male babies and recessive in female babies. Primarily, less baldness is inherited from dad to son. If the father is bald and the grandfather is also bald, the incidence of a boy is about 100%.

If the father is not bald and the maternal grandfather is less bald, there is a 25% chance that the baby boy will be bald; If the father is not bald and the grandfather is full of thick hair, the probability of the baby being bald is almost zero. Because baldness is generally inherited from generation to generation, for example, my grandfather is bald, and so is my grandson.

This is because the grandfather's bald X chromosome was given to the mother. The mother is a carrier of normal performance because only one of the two X chromosomes has a baldness gene, the other is normal, and baldness is a recessive gene. If a mother gives birth to a son, there is a 50% chance that she will get a chromosome with the baldness gene.

If the son unfortunately inherits the X chromosome from his mother with the baldness gene, then he will be bald. Because men only have one X chromosome. There are also many causes of baldness, some of which are acquired, such as nutrition or disease.

If it is an acquired baldness, it can generally be recovered through surgery**. These include male alopecia, domed baldness, seborrheic baldness, baldness due to disease, medication-induced baldness, or telogen baldness. Among them, telogen baldness is mostly caused by stress that causes the telogen phase to prolong and fall out, and once the stress is relieved, the hair will grow back.

In addition, baldness caused by illness or due to the use of drugs such as anti-cancer drugs, if the disease is obtained** or after the drug is stopped, most of the hair can grow back. Dome baldness, commonly known as ghost shaved head, is mainly the hair falling out of the circular area of the head, showing single or multiple circular baldness, the reason may be related to autoimmune machine rotation and emotional stress, generally it will heal within half a year, and only a few will develop total baldness. <>

Among hair loss, hereditary hair loss patients account for a large part, and hereditary hair loss is not only inherited by parental hair loss, but also some patients are passed on from generation to generation. There is currently no clear way to determine hereditary hair loss, because hereditary hair loss is inherited from genes and cannot be detected by current medical equipment. However, there are several simple ways to determine whether it is hereditary alopecia

One is to look at the location of hair loss, baldness, M-shape, and sparse crown of the head are the main location areas of hereditary hair loss. The second is the degree of hair loss, if the hair loss has been clearly visible to the scalp, sparse and large, basically except for hereditary alopecia and alopecia universalis, there will be no such serious hair loss. The third is to look at the family situation, if the parents and grandparents of the immediate family have hair loss, then the possibility of hereditary hair loss will be very large.

If it is caused by low hair, psychological stress, bad habits, improper care, etc., it will not be inherited. <>

Seborrheic alopecia is indeed related to genetics. At present, it is believed that the disease is a polygenic hereditary disease, the probability of seborrheic alopecia in the father, the disease in the son is 50%, and the age of 18 in men is the initial stage of the disease, and there is a trend of younger people.

The current medical technology can stop more than 90% of patients and partially restore growth in about 70%, but early, long-term, standardized, combined, and individualized comprehensive interventions are needed to achieve satisfactory results.

Hair loss and heredity have a certain relationship, but also have a certain relationship with usual care measures, if you usually dye your hair often, it will lead to serious hair loss, if the hair loss is more serious, you can change it by planting hair, and you must do a good job of hair care in ordinary times, such as giving more nutrients to your hair.

The probability of hereditary hair loss is not 100% passed on to offspring. It still depends on the hair loss, whether it is dominant inheritance or recessive inheritance. It also depends on the probability of hair loss in the parents. It can only be guessed based on the parents' street scenes.

What are the chances of inheriting hair loss? The hereditary probability of this hair loss is not so great, it can be about 30%, and it should not be absolutely inherited.

In fact, genetics play a decisive role, but it is not the only factor. Even if you have hair loss genes, whether the next generation will lose hair or not is not determined by genetics alone, it also has a certain randomness. Hereditary hair loss is rooted in the persistent suppression of hair follicles by a special hormone, DHT (dihydrotestosterone, a male hormone).

Studies have found that people with genetic hair loss have DHT in the scalp on the top and front of the head, and the concentration level is very high, which can promote hair follicle atrophy, shorten the hair growth cycle, and lead to thin, thin, and falling out of hair.

Most of the hereditary hair loss heads, in men, show M-shaped loss on both sides, gradually spreading to the top of the head, receding hairline or hair loss at the back of the head. The female feature is diffuse on the top of the head, spreading from the top of the head to the sides.

And due to the strong secretion of male hormones, many people often show that their hair or face is very oily, dandruff is more, scalp itching, etc., and it is worth mentioning that hereditary hair loss generally develops rapidly.

In fact, according to different types of hair loss, the genetic situation is also different, if it is only because of mental pressure, or malnutrition, poor rest and caused by hair loss, it will not be passed on to the next generation, but if it is seborrheic alopecia, it is very likely to be passed on to the next generation, we must strengthen the understanding of relevant knowledge, and prevent it as soon as possible.

Hair loss doesn't necessarily inherit from him alone. Physical conditions such as staying up late, stress, anxiety and other reasons can lead to hair loss.

Is hair loss necessarily hereditary? This genetic factor is not absolutely large, there is a little bit of heredity that is not absolute.
