The Science Behind Why Hair Goes Grey
Hair colour comes from melanocytes, the cells in our follicles that produce pigment. As we age, these cells gradually slow down — and eventually stop — producing the melanin that gives hair its colour.
Genetics set most of the timing. If your parents went grey early, you probably will too. But emerging research is also exploring how stress, oxidative damage, and certain nutritional deficiencies can accelerate the process.
The Going Grey Research Fund supports peer-reviewed studies that help us understand not just why hair greys, but how the experience reshapes identity — because every honest study makes the conversation a little less anxious for everyone who comes next.
