‘Cell Stress’ Grays Hair says National Geographic
It is commonly understood that stress is a factor in turning hair gray, so that you had people who had their “hair turn grey from worry”, but now a new study has found that it is also cell stress that is a factor responsible for graying of our hair.
Our very DNA is constantly under attack from damaging agents, such as chemicals, ultraviolet light, and ionizing radiation, according to study as reported by the National Geographic. The lead author of the study has estimated that a single mammal cell can encounter up to 100,000 events a day that damage DNA and that the stem cells within hair follicles responsible for color are the most impacted by this irreparable DNA weathering.
So this is one more advancement in understanding why our hair becomes gray, including factors such as chemicals that hair comes into contact with, such as hydrogen peroxide etc.
There are, after all, ways to Go Gray Gracefully!
