I do not think I'm the only person with this doubt, because of me intrigue I decided to consult with some relatives and acquaintances in the area of ​​medicine to get out of this doubt.

Based on my conclusions and the information that these people gave me, all of the following is concluded.

There is a group of male sex hormones called androgens which is primarily responsible for this act.

Much of their work is to stimulate the development of secondary sexual characteristics.

Among these are:

Body mass.

There is an androgen responsible for facial hair, which is called DHT. This androgen all produce it, but not all have the same number of receptors on the skin.

The less receptors a person has, the less facial hair they will have.

The more receptors a person has, the more facial hair they will have.

There is also a large group of people and studies, which ensure that DHT androgen also causes hair loss.
