Red hair can turn brown due to a decrease in production of the pigment responsible for red hair (pheomelanin) and an increase in production of the pigment responsible for brown hair (eumelanin). This change in pigment production can be influenced by genetics, hormonal changes, aging, or exposure to sunlight.
Immature hair follicles do not necessarily secrete as much pigment as they will when they have matured.
Hair is colored by three types of pigment: phaeomelanin (red-colored), brown eumelanin, and black eumelanin. Depending on the amount of pigment in each hair, the hair will be any shade from blond to black. Higher amounts of pigment make darker colors, and lower amounts make lighter colors.
No. There is no purple hair because hair and skin color is made from a pigment substance known as melanin. There are basically only two types of melanin: black which is known as eumelanin and orange/red known as pheomelanin. The third type is what most of humanity is and that is a combination of the two: pheomelanin and eumelanin. Natural color of hair is sort of straw like yellow. There is no natural occuring purple, or true red in hair. You would need a true red and blue to make the purple, neither of which occurs in humans

Melanocytes in the hair follicles. These pigment-producing cells create melanin, which determines the color of the hair. Different amounts and types of melanin result in various shades of hair color, from black to blonde to red.
The short answer is Melanin.Phaeomelanin is responsible for the yellowish-blond to red colors and Eumelanin is responsible for the brown to black shades. Gray hair occurs when humans stop producing these melanin molecules. Grey/white hair is what hair looks like when there is no pigment.
Pigments are materials that are used to add color to different things, and the pigments themselves are often found as fine granules suspended in what they are adding color to. In the case of paint, for example, white paint has a red pigment added, and the actual material that gives the paint the red color is finely ground "red" pigment. The red pigment granules are suspended in the paint, and the paint will then appear red.

Melanin is the main pigment found in human skin, hair, and eyes. Hemoglobin is the red pigment found in red blood cells. Bilirubin is a yellow pigment formed from the breakdown of heme in blood. Lipofuscin is a brownish pigment that accumulates in aging cells.
what does the pigment do in a red blood ell
When every human is born their hair creating cells are "programmed" to include a certain color of pigment into new hair cells, which are naturally white. However, as a person ages, the pigment producing cells start to disintegrate, consequently, creating in less and less pigment to incorporate into newly produced hair (hair grows 100 nanometers every second). This results in hair color decreasing from a vibrant red or brown to gray. Lighter color hair, such as blonde, will loose all of its pigment, resulting in white hair.
