The pigment that gives color to hair, skin, and eyes

Melanin is a crucial pigment produced in the body that plays a significant role in determining the color of hair, skin, and eyes. It is found in varying amounts and types in different individuals, which leads to the diversity of human appearance we observe. The production of melanin occurs in the melanocytes, specialized cells located primarily in the skin and hair follicles.

This pigment serves not only an aesthetic function but also an important protective role; it helps to absorb and dissipate harmful ultraviolet (UV) radiation from the sun, reducing the risk of skin damage and certain types of skin cancer. Therefore, the correct identification of melanin as the pigment responsible for coloring in various parts of the body is fundamental to understanding its biological significance in terms of both appearance and function.
