Understanding Gray Hair

The video explains how hair turns gray as people age due to the depletion of melanin, the pigment responsible for hair color. Hair grows from follicles, which contain melanocytes that produce melanin. Over time, these melanocytes decrease, leading to gray or white hair. The process is gradual, with most people experiencing gray hair in their 30s or 40s, and more extensively by their 50s or 60s. Some choose to dye their hair, while others embrace the natural change.
