What's up with the white nose hair

Normal people's nose hair is black, which is the same as our body hair, armpit hair, pubic hair, etc. If our body lacks vitamins and melanin, it will easily lead to gray hair. Especially after people reach old age, this phenomenon will become more and more obvious. Our nose hair will turn white last, just like the nose hair of albinos is white. So what is the reason for the white nose hair?

Whitening of nose hair can identify whether a tumor is good or bad. Is this a legend or a fact?

Changes in hair color are directly related to the functional decline of hair pigment cells. When the pigment is no longer produced, the hair turns white. According to current medical knowledge, there is no scientific basis for identifying the stage of tumor progression by observing the color of nose hair.

What is white nose hair?

1. The whitening of nose hair is a phenomenon of aging. The less pigmented hairs replace the more pigmented hairs until all the pigmented hairs are replaced. Nose hair is considered an important marker for determining a person's age and aging relatively reliably.

Experts recommend: Eat purple rice, black beans, black sesame seeds, walnuts, etc. regularly. In addition, you also need to eat carrots, spinach, purple radish, etc. regularly, which are beneficial to the maintenance of hair color.

2. If you are around 40 or 50 years old, it is normal to have white nose hair. Some people have white hair in their twenties or thirties. This is hereditary. The situation of nose hair is the same as that of head hair. This phenomenon is also quite common among ordinary people.

This is a phenomenon of "individual" hair "whitening", which is not surprising at all, and it does not mean that you are old. There are two types of age: physical age and mental age. Being young at heart is more important.

What is the function of nose hair?

Nose hair is the first line of defense against respiratory diseases, and it has three functions.

① Nose hair can block dust, bacteria, etc. in the air, allowing the human body to inhale filtered clean air. At the same time, the action of cilia in the nose can also allow some bacteria to enter the stomach along with mucus, and be killed by stomach acid.

② Nose hair can maintain the temperature of the nasal mucosa, prevent the outside cold air from being directly inhaled into the trachea, and keep the nasal mucosa moist, which helps prevent dry or atrophic rhinitis and nose bleeding.

③Nose hair can protect the olfactory nerves from damage, allowing the nose to smell various odors and transmit the aroma of food to the brain, increasing appetite.

When larger foreign objects, such as insects and grass clippings, enter the nasal cavity, the nasal hair not only blocks them, but also transmits information to the nervous system, causing sneezing to clear them out.
