Depending on your hair''s natural color, it contains one or two different types of melanin: Eumalin is the most common and is responsible for darker hair shades, including chestnut, coffee, and black, while phaeomelanin contributes to light and reddish tones such as blonde, caramel, ginger, and auburn. The murine Agouti gene encodes a paracrine signaling molecule that promotes follicular melanocytes to produce yellow phaeomelanin pigment instead of black eumelanin pigment. There are two different types of melanin, eumelanin with black pigments and phaeomelanin with yellow pigments. |
