Red Seal Cosmetology Practice Exam

Eumelanin is a type of pigment found in humans and animals that is responsible for the dark brown to black color of hair, skin, and eyes. It is produced by melanocytes in the skin and is the most abundant form of melanin in the human body. Options A, B, and C are all incorrect as eumelanin is not associated with these colors. Red hair is typically the result of a different type of pigment called pheomelanin, while yellow and green are not commonly found in human pigmentation.
