- 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.

And roar from yonder dropping day:
The last red leaf is whirl’d away,
The rooks are blown about the skies;
The forest crack’d, the waters curl’d,
The cattle huddled on the lea;”

“Analysis does not set out to make pathological reactions impossible, but to give the patient’s ego freedom to decide one way or another.”
—Sigmund Freud (1856–1939)

They give us, now and then, some of those luxurious sterile emotions that have a certain charm for the weak.... They are simply cheques that men draw on a bank where they have no account.”
