Types of Melanin... People have three types:

1. Eumelanin makes mostly dark colors in hair, eyes, and skin.

There are two types of eumelanin: brown and black.

Black and brown hair come from different mixes of black and brown eumelanin.

Blonde hair happens when there’s a small amount of brown eumelanin and no black eumelanin.

2. Pheomelanin colors the pinkish parts of your body like the lips and nipples.

You get red hair when you have the same amount of pheomelanin and eumelanin.

Strawberry blonde hair happens when you have brown eumelanin and pheomelanin.

3. Neuromelanin Controls the colors of neurons.

It isn't involved with the coloring of things you see.

When you're in the sun, your body makes more melanin... It help’s protect the body from harmful ultraviolet (UV) rays.

*The key difference between Eumelanin & Pheomelanin is the fact one is sulphur based (pheomelanin), the other selenium (eumelanin); when exposed to sunlight pheomelanin turns carcinogenic.
