It is generally ineffective to wash rice and turn white hair into black hair.
The production disorder of melanin particles is usually related to diseases and human aging. It is not scientific to use Taomi water to treat white hair. White hair is mainly due to the formation of melanin particles in the hair papilla and hair ball. Or there is a problem in the transportation process, which causes melanin particles not to be transported to the hair shaft normally. The decrease of melanin particles in the hair cortex and medulla may lead to hair whitening and pigment disappearance.
When gray hair first appeared, most people pulled it out by hand:
When it was too late to pull it out, they had to give up, so they felt that it was because of pulling gray hair that their hair became whiter and whiter, so they came up with the saying, "Pull one, and ten will grow".
this statement makes friends who have just discovered white hair very entangled. They dare not pull it out easily, and they are reluctant to dye their hair for a few dozen white hairs.
Under normal circumstances, the number of scalp hairs has been fixed at birth, about 1, hair follicles. With the increase of age and scalp surface area, the density of hair follicles will decrease.
The density of newborns is 1,135 per square centimeter, and then gradually decreases, reaching 615 per square centimeter at the age of 2-3, 485 per square centimeter at the age of 3-5, and only 435 per square centimeter at the age of 7-8. At this point, the naked eye will see sparse hair.
Therefore, it is incorrect to say that one root is ten long. However, although forcibly pulling out the white hair will not make it grow longer and more, it will hurt the hair roots, especially? If the hair is pulled out too much, it may also cause folliculitis, especially in the case of unhealthy scalp. Cases of furuncle after hair pulling are often seen in clinic.
