I am pretty sure you are thinking of melanin. Melanin gives basically everything on our body colour including our hair, skin, iris etc.
The cells that produce the pigment in hair are called melanocytes.
Melanocytes are specialised cells that produce melanin. Melaninproduces pigment, a colour, which is found in the skin, hair and in the iris of the eye.
Moles can have hair because they are made up of cells that produce pigment and hair follicles. The hair on moles is usually fine and light in color, and it is a normal part of their appearance.
Each hair follicle contains a certain number of pigment cells. As we age the pigment cells in the hair follicles gradually die and the hair turns gray, silver, or white.
Dark hairs can grow out of moles because the cells in moles produce pigment, which gives the hair its color.
She has a lot of melanin in her hair. Melanin is the pigment that gives human hair, eyes, and skin their color. Cells called melanocytes produce melanin.
Moles grow black hair because the cells in moles produce melanin, a pigment that gives hair its color. The melanin in moles is usually darker, resulting in black hair.
Keratinocytes or squamous cells produce keratin and Melanocytes produce melanin, pigment.
As we get older, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become a more transparent color.
As we get older, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand for hair will no longer contain as much melanin and will become a more transparent color, like gray, silver, and white, as it grows. As people continue to get older, fewer pigment cells will be around to produce melanin. Eventually, the hair will look completely gray.
Melanocytes are cells in the skin that produce a pigment called melanin.
Hair can grow longer out of moles because moles are areas where skin cells produce more pigment and hair follicles can become more active, leading to longer hair growth.
