With the increasing competition pressure in modern society, people’s working rhythm is also accelerating, many people are troubled by white hair.
So, what causes the hair to turn white? Scientific research shows that there are many factors leading to white hair, everyone is different, only to find the cause of their hair white, can fundamentally improve the situation of hair white.
Also often hear people say, white hair pull a long 10 root. So, is there a scientific basis for this statement? Today, we will bring you to the detailed chat!
Is it accurate to pull a 10-root claim?
It is often said that white hair can not be pulled, because “pull a long 10”. The truth is: Under normal circumstances, the number of hair in the scalp is actually in the shape of the birth period, the average person has about 100,000 hairs. As the age increases, the hair follicle will decrease, the newborn density is 1135/cm2,20-30 years old 615/cm2,30-50 years old for 485/cm2,70-80 years old only for 435/cm2, this is also the reason for the thinning of the elderly.
The growth period of hair is divided into growing period, retreat departure and repose time. The growth period of the hair is 4-6 years, the retreat departure is 2-3 weeks, the repose is about 3 months. Each hair has its own growth cycle, and unplugging white hair only shortens the lifespan of the white hair and may grow new white hairs in the hair follicle.
To sum up, it is unscientific to draw a 10-root claim. Although unplug white hair will not be longer and more, but the hair will be removed to damage hair root, serious will lead to skin inflammation.
The physiological mechanism of white hair
White hair refers to all or part of the white hair, because the hair medulla and cortex melanin particles reduced or by air, the reasons for the congenital and acquired two. Congenital white hair often has familial genetic correlation. Acquired white hair is mainly senile white hair and juvenile white hair.
Under normal circumstances, the hair nipple has rich blood vessels, for the hair nipple, the Wool Ball department provides the sufficient nutrition, the melanin particle then smoothly synthesize. When the melanin particles in the hair nipple, the formation of the fur ball barrier, or although the formation of some factors, can not be transported to the hair, so that the hair medulla, cortical parts of the melanin particles reduced, disappeared, there will be white hair.
