Do darker people have more melanin than lighter skinned people?

I think that they have kinkier hair but I'm not sure on the melanin.

Yeah she's right. The fact that the melanin is closer to the surface on the cells (melanocytes) makes it more susceptible to genetic mutation so they are more likely to develop melanoma (skin cancer)

yes darker people have more melanin than lighter skinned people

As a hair colourist, I have to deal with Melanin pigments every day.  It is not that fair people or dark people have more or less melanin pigments than the other, they simply have DIFFERENT types of pigment  Darker pigments are an abundance of melanin specifically called Euomelanin, while lighter pigments are in abundance of Pheomelanin.  Neither has more or less, just different types of Melanin is all.  While this is coming from a hair stylist pigments are pigments whether they are skin or hair, doesn't matter the rule and types are the same.  Hope that helps

Yes. Melanin is what makes them darker... Example: Black hair contains a lot of melanin compared to light brown.
