What does it mean when a girl has armpit hair?

Armpit hair is a relatively common type of hair, and the growth of armpit hair on girls' armpits is also a relatively normal physiological phenomenon, so there is no need to worry about this situation. Of course, existence is reasonable, and the existence of armpit hair also has its special functions, such as preventing bacteria and relieving friction. If girls who love beauty want to remove their armpit hair, they also need to pay attention to taking normal methods!

1. Reasons for the growth of armpit hair

Armpit hair exists in the human body, generally in both men and women. The growth of hair is related to the estrogen and testosterone in the human body, which means that women generally have armpit hair when they reach adulthood.

Armpit hair is located under the armpits and is also one of the secondary sexual characteristics of women. Similar to pubic hair, it is the result of the adrenal glands beginning to secrete estrogen and testosterone. Armpit hair appears 1-2 years later than pubic hair, and the average age abroad is 12-15 years old. Chinese women also start to develop armpit hair around the age of 12-15.

2. The role of armpit hair

1. Antibacterial

Armpit hair can shield and protect the skin where it grows, preventing it from being invaded by foreign bacteria, dust, etc., and keeping the "enemy" out of the skin.

2. Relieve friction

Another function of armpit hair is that when the human body moves, the arms move, and the armpits always generate friction between the surrounding skin. If the friction is too long or too heavy, it often rubs in the "middle", which relieves the force of skin friction and protects the armpit skin from being scratched. Therefore, the role of armpit hair cannot be denied. Many women often pluck or shave their hair for beauty, which is harmful to the body. Because the armpits are rich in lymph nodes, plucking or shaving armpit hair is likely to cause epidermal infection and pose hidden dangers. Therefore, the correct way is to use round-head scissors to trim, which is both beautiful and will not scratch the skin.

The presence and distribution of hair on the human body is one of the ancestral characteristics that humans have retained as they evolved from apes to humans. On the body surface of a normal adult woman, except for the palms, soles of feet, the back of the distal ends of the fingers and toes, lip lines, nipples, inner sides of the labia majora, labia minora, and clitoris, there should be hair growing everywhere, but there are some differences.

3. Things to note about armpit hair

Once armpit hair grows, the armpits often become sweaty. Compared to when I was a child, sweat has a special smell. If it is not cleaned in time, it will soon emit an unpleasant odor, commonly known as body odor. If frequent bathing and changing of clothes does not improve the condition, it is best to see a dermatologist.

It is not advisable to cut armpit hair: Some people think that it is unsightly to expose armpit hair when wearing short-sleeved clothes in summer, so they cut it with scissors, and some use blades to shave armpit hair. In fact, doing so is wrong and harmful to health. Whether you cut or shave your armpit hair, you cannot prevent the normal growth of armpit hair, and it is very easy to cause bacterial infection in the armpit. We should face up to the normal physiological phenomenon of armpit hair and never harm our health because of some wrong views.
