Why Do Humans Have Grey Hair? A Biologist Explains What’s Happening
Biologists explain that human hair greying is primarily caused by the failure of melanocyte stem cells to maintain pigment production during hair growth cycles. While often associated with aging, the process is a natural biological phenomenon that does not serve a clear evolutionary function.
Why it matters
Understanding the cellular mechanisms of aging helps demystify common physical changes and contributes to broader research in regenerative biology.
