Pigmentation refers to the coloring of skin, hair, eyes, and other tissues in living organisms, primarily determined by the type and amount of melanin produced by melanocytes. It plays a crucial role in protecting against UV radiation and is influenced by genetic, environmental, and hormonal factors.
Biological pigments are substances produced by living organisms that have color due to selective color absorption. They play crucial roles in various biological processes, including photosynthesis, camouflage, and signaling.
Melanin is the primary pigment responsible for the color of human hair, produced by specialized cells called melanocytes. Variations in type and amount of melanin lead to a wide range of hair colors from black to blonde, with different genetic, environmental, and aging factors influencing this pigmentation process.
The pigmentation process refers to the production and distribution of pigment molecules, primarily melanin, which determine the color of skin, hair, and eyes in humans. This process is influenced by genetic factors, environmental exposure such as UV radiation, and certain hormonal changes in the body.
Hair pigmentation is primarily determined by the type and amount of melanin produced by hair follicles, which in turn is influenced by genetics. The two main types of melanin, eumelanin, and pheomelanin, are responsible for the wide range of natural hair colors, from black to blonde and red.
