Blue hair does not naturally occur in human hair pigmentation,[1] although the hair of some animals (such as dog coats) is described as blue.

Some people (typically of East Asian descent) are born with black hair that is so dark that it appears to have a metallic blue luster. In Japan, the beauty ideal for a woman is to have glossy "blue-black" hair,[2] and Western foreign observers have also held this quality in high regard.[3]
