Is growing gray hair a good thing for our health? Listen to what the Harvard study has to say

Regarding the rumor circulating on the Internet that "always growing gray hair is not easy to get cancer", the Internet rumor is from researchers at the Department of Dermatology at Harvard University. The researchers believe that the formation of gray hair is actually a self-protection mechanism of the body . Grey hair means that the genes of the melanin-producing stem cells have been damaged and removed.

If the damaged liver cells are not removed , they will replicate like crazy and form cancer cells, so this study concluded that people with gray hair are less likely to develop cancer.

However, doctors from Beijing Cancer Hospital said that some of these statements are too one-sided. The causes of melanoma and gray hair are both complex processes.

Every part of the body has reasons for the malignant transformation of melanocytes , which are likely to be closely related to factors such as sunlight and genes.

The formation of gray hair is more complicated, including heredity , age, life, disease, diet, etc., so there is no such thing as "always gray hair is not easy to get cancer".
