pheomelanin (High amounts)
eumelanin (low amounts)
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

Hair turns gray when the pigment cells located at the roots of each indivdual hair die. Therefore, unless certain parts of red-haired-peoples body's are immortal, red hair does turn grey.
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.
yes
what does the pigment do in a red blood ell
the pigment is fading in your hair
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.
The answer is definitely not swine flu. A lack of Melanin, which is is the pigment that gives color to hair and skin, causes Amelanosis, commonly known as albinism.
