Is paternal hair loss hereditary?

In genetics, hair loss is a relatively complex genetic phenomenon, and it can even be passed down from one generation to another. But hair loss is also divided into male and female. Can hair loss from the father be inherited? If the father has hair loss, it is true that the child will also have hair loss, but the probability of boys inheriting it is higher, and the probability of girls is lower. However, we cannot just look at the father's hair loss, but also need to connect it with whether the parents have hair loss.

We know that there are many reasons for hair loss, and among many people with hair loss, there may be a family history of hair loss. Does this mean that hair loss is hereditary? In fact, there are many types of hair loss, some of which do have a certain hereditary probability. So does it mean that if the father has hair loss, it will definitely be hereditary? Let's learn about this issue together.

In fact, there is a certain genetic probability for hair loss, but it depends on the specific situation. Generally speaking, if the father has hair loss, that is, if the male carries this gene, he will definitely be bald, but the severity varies. If the mother has this gene, she may not have hair loss, but it is possible to pass it on to the next generation. From this, it can be seen that men carrying the hair loss gene are dominant, while women carrying the hair loss gene are generally not visible, so when it is inherited, it is not necessarily the father's fault.

Generally speaking, men have a higher chance of hair loss than women. We can assume that the hair loss gene is a and the gene that does not cause hair loss is A. The only men who do not cause hair loss are men with AA, while men with Aa or aa will suffer from hair loss. As for women, only women with aa will suffer from hair loss, while women with Aa or AA will not suffer from hair loss.

Therefore, genetic hair loss depends not only on the father but also on the mother. We cannot blame men entirely. Strictly speaking, the son's hair loss gene is more related to the mother. If the mother has hair loss, then the probability of her son having hair loss is higher than 50%; the daughter's hair loss gene is more related to the father. If the father does not have hair loss, then the daughter will not have hair loss, no matter what the mother's situation is.

From the above introduction, we know that it is uncertain whether the father's hair loss will be inherited. This is related to the gender of the offspring and the mother's hair loss condition. Regardless of the high or low probability of hair loss inheritance, it is recommended that those with a family history of hair loss should pay more attention to hair care in order to prevent improper care from increasing the probability of hair loss, thereby causing greater trouble to themselves.
