Most of us have heard of melanin. It is a pigment, but there are actually two types of melanin which give hair and skin its colour. One of these is pheomelanin, which gives the body pink and red tones.
Pheomelanin can be found in both light and dark-skinned people although females usually have more than men. That’s why women tend to have slightly pinker skin than men, particularly on thin skinned areas like the lips.
We all have at least some pheomelanin in our hair, but it stands to reason that redheads have more than anyone else. BIt is also prominent in blondes, offering yellowy undertones.
