There is two main pigments found in human hair: Eumelanin has an oval or elliptical shape, which gives color to brown or black hair and is dark pigment. The higher the concentration of Eumelanin the darker the hair. Pheomelanin is what produces the color in blonde or red hair.
The blood also carries away waste from the skin. The dermis is home to the hair follicles, the sebaceous glands and the sweat glands. The hair follicles and the sebaceous glands are in close proximity and actually are connected. The hair follicles, of course, produce hair and there are tiny muscles attached to them.he epidermis is also where you will find melanin, which is produced by cells in the epidermis called melanocytes. Melanin is what gives our skin the color it has. The more melanin, the darker the skin. It provides some protection from the burning rays of the sun.
