Hair is an important part of our body and an essential part of our skin. However, many people do not want to have a lot of hair on their bodies due to different aesthetic concepts. In fact, both men and women usually have armpit hair, but men usually have more armpit hair. Hair is a manifestation of male testosterone. When does a boy's armpit hair grow?

When does a boy's armpit hair grow?

Generally speaking, when men reach the stage where their secondary sexual characteristics begin to develop, their hair starts to grow, and that is when their armpit hair also starts to grow. However, some men are born with low hormone levels and may never have armpit hair throughout their lives.

The growth of armpit hair coincides with the appearance of male sexual characteristics, but not all men have armpit hair. This is similar to the fact that many men do not have dense hair or scalp hair, so it depends on individual physique.

Two main uses of armpit hair

1. Antibacterial protection for armpits

Human armpit hair, like pubic hair, can cover the body surface where it grows and protect the human skin from invasion by foreign bacteria, dust, etc.

2. Relieve skin friction

Another function of armpit hair is that when the human body moves, the armpits will pull the surrounding skin and there will always be friction. If the friction lasts too long, it will relieve the force of skin friction and protect the skin in the armpits from being scratched.

Can armpit hair be plucked?

It is best not to pluck armpit hair randomly. If the armpit hair is plucked thoroughly, it will be very clean and the regrowth rate will be relatively slow. It is estimated that it can last for one or two weeks or even longer. However, it is recommended not to choose to pluck armpit hair lightly, because plucking armpit hair may cause problems such as hair follicle infection.

Because the skin under the armpits is thin, tender and sensitive, using tweezers, pulling it out with bare hands or using depilatory wax is a very painful process. In addition, if the pulling method is improper, it will cause certain damage to the skin under the armpits, not to mention pulling it out by the roots. Therefore, pulling out armpit hair is extremely damaging to the hair follicles.

In addition, the skin under the armpits has crevices that are prone to sweating. If the skin environment is relatively humid and hot, it is easy to cause bacterial infection or inflammation when plucking. Therefore, it is recommended not to pluck armpit hair easily to avoid damaging the sweat glands under the armpits.
