Why do boys have long nose hair?

If a girl sees a handsome boy, but observes his face carefully and finds that his nose hair is very long, it is really a bad thing. But for most boys, their nose hair is very long, which is the result of the secretion of male hormones in the male body. However, nose hair can only be removed by mastering the correct method, so what is the specific reason for boys' excessively long nose hair?

1. Genetic factors: The length and thickness of nose hair vary from person to person, and this is not caused by bad habits. Long nose hair can indicate that the person is healthy and has more abundant hair in that area; the nose hair grows longer due to natural heredity.

2. Climate environment: When we are in an environment with poor air quality for a long time, our nose hair will grow longer to prevent harmful substances from entering the body.

Lifestyle habits: Smoking will cause nose hair to grow longer. People who breathe more heavily will also have their nose hair grow longer as a defense mechanism in order to filter out air impurities.

Nose hair, like hair on other parts of the body, consists of two parts: the hair shaft exposed outside the skin and the hair root buried inside the skin. This constitutes a complete tissue structure and becomes an essential component of the human body barrier - the skin. Nose hair has a certain defensive function. Nose hair growing in the front of the nose is like thorns set at the entrance of the cave, which can block the invasion of some "foreign enemies". It can prevent larger dust particles from being inhaled into the nasal cavity with the airflow. Workers who work in high dust (such as coal miners) are often seen. After a day's work, the nostrils are the darkest part of the body. This is because the nose hair causes the coal dust particles to settle in the front of the nose.

1. Pulling out nose hair can cause a lot of harm. If you pull out your nose hair, you will destroy this integrity and balance. Pulling out nose hair is equivalent to removing the sentinel guarding the door to the respiratory tract, allowing dust and bacteria to enter the human body unimpeded and cause illness.

2. When you pluck out your nose hair, you also damage the mucous membrane where the nose hair grows, which can easily cause rhinitis, folliculitis, and soft tissue infection. Plucking out your nose hair will damage the mucous membrane inside your nose, enlarge your pores, and make them more susceptible to invasion by harmful substances.

3. After cutting, just like shaving, the hair will grow thicker and harder, making it easier to show through the nostrils.
