As an expert in the field of genetics and human biology, I can provide you with information on the average age people typically start to go gray. Hair graying is a natural process that occurs as cells in hair follicles that produce melanin, the pigment that gives hair its color, gradually stop functioning. This process is influenced by a combination of genetic and environmental factors.

The average age to go gray varies significantly among individuals and across different populations. However, generally speaking, people begin to notice gray hairs around their 30s and 40s. Some individuals may start going gray as early as their 20s, while others may not see any gray hairs until their 50s or even later. It's important to note that the onset of gray hair can be influenced by factors such as genetics, stress, smoking, and certain medical conditions.
