Extension - gray hair can't be pulled out, is it true that the more you pull out?
Nowadays, many young people have white hair. Some people think that the white hair will be plucked out, and the more it will be plucked. Others believe that after the white hair is pulled out, the white pigment will 'contaminate' other black hair follicles, causing more and more white hair to be pulled out. .
In this regard, experts say that there is no so-called white pigment in the body. You won't be pulling out more and more gray hair. The growth of black hair mainly depends on the hair roots formed by melanocytes.
As we age, the pigment cells at the root of the skin stop or reduce the formation of melanin, which results in white hair. Experts say that normal hair is black because of melanin, melanin, and white hair is because there is no melanin.
Also, it is recommended not to forcibly remove gray hair. While plucked gray hair won't make it grow longer, it can damage the roots and, especially if plucked too much, can also lead to folliculitis.
