There are three different types. First, there is eumelanin. Eumelanin is a type of melanin that is most abundant in humans. It is found in people who have black, brown skin and hair. Second, we have pheomelanin which is most common in people who have red hair and freckles. These individuals will have a very high sensitivity to sun exposure(caucasians). Lastly, there is neuromelanin. This type of melanin is found in the brain. It allows you to be able to walk, talk, think and see. Basically, it helps to process information. When neuromelanin has been compromised, Parkinson’s and other neurological diseases may begin to form.
