whitening of nose hair
Introduction
Introduction It is generally considered that the function of hair pigment cells is degraded, and when it is degraded to a point where no pigment can be produced at all, the hair becomes white. Reasons include genetic factors, mental factors and nutritional factors. When the hair is whitened, the hair with a small amount of pigment replaces the hair filled with the pigment until all the pigmented hair is replaced. More clearly than the hair, it is the whitening of the nose hair. Nasal hair can be whitened not only like other hairs, but is also considered to be an important indicator for determining a person's age and aging more reliably.

The nose hair is only born at the entrance of the nostrils, and the number is small. It is different from the hair and does not become thinner with age. Therefore, it is relatively easy to check the degree of whitening and whitening. The whitening of the nose hair starts more than 36 years old, and almost all white when it is over 50 years old.

According to Japanese scholars, the relationship between male nasal hair bleaching and age is: under 20 years old, 0%; 20-25 years old, 50.%; 26-30 years old, 19.4%; 31-35 years old; 27.7%; 36-40 Years old, 63.0%; 41-45 years old, 72.3%; 46-50 years old, 94.7%, over 51 years old, 100%.
However, the inspection of more than a thousand people in China shows that the age of male nose hair whitening is much later, and the whitening rate is much less. In China, the nose hair whitening first appeared in the 31-35 age group, with an average of less than 3%; the 51-55 age group averaged less than 30%.
