summary

With the increasing pressure in modern life, many young white-collar workers have more and more white hair. In addition to the natural generation of physiological white hair with age. The white hair caused by pressure, psychology, disease and environment is more and more perplexing the urban population. Here's why there are more and more ShaoBaiTou.

Why less white head more and more

First: white hair is due to the reduction of melanin particles in the medulla and cortex of the hair or the air filling. Under normal circumstances, there are abundant blood vessels in the dermal papilla, which provide sufficient nutrition for the dermal papilla and the hair bulb, and melanin granules can be synthesized smoothly. When the formation of melanin particles in the hair papilla and hair bulb is obstructed, or although they are formed, they cannot be transported to the hair due to some factors, so that the melanin particles in the medulla and cortex of the hair are reduced and disappeared, white hair will appear.

Second: it is often said that white hair can not be pulled out, because "pulling out one long ten.". This is unscientific. The hair follicles surrounding the hair are actually formed at the time of embryo formation. Although not necessarily one hair follicle grows one hair correspondingly, the number of hair is regular. According to statistics, the average person has about 100000 hairs. With the growth of age, hair follicles will decrease, which is the reason why the elderly have less hair. Because the number of hair is a certain, so "pull one long ten" argument does not hold. It is often said that if a newborn has shaved his head, his hair will be thicker and more, which is also groundless from a scientific point of view

Third: white hair is mainly due to the reduction of melanin particles in the medulla and cortex of the hair or the air filling. When the formation of melanin particles in the head and bulb of hair is obstructed, or the melanin particles in the medulla and cortex of hair are reduced or disappeared due to certain factors, the white hair will appear.
