- One variety of albinism (Type 3, aka rufous albinism), sometimes seen in Africans and inhabitants of New Guinea, results in red hair and red-colored skin.
- Red hair is found on people lacking pro-opiomelanocortin.

In an old cellar hole in a byroad
The origin of all the family there.
Thence they were sprung, so numerous a tribe
That now not all the houses left in town
Made shift to shelter them without the help
Of here and there a tent in grove and orchard.”
