In this way, high frequencies of light hair in northern latitudes are a result of the light skin adaptation to lower levels of solar radiation, which reduces the prevalence of rickets caused by vitamin D deficiency.The darker pigmentation at higher latitudes in certain ethnic groups such as the Inuit is explained by a greater proportion of seafood in their diet and by the climate which they live in, because in the polar climate there is more ice or snow on the ground, and this reflects the solar radiation onto the skin, making this environment lack the conditions for the person to have blond, brown or red hair, light skin and blue, grey or green eyes.An alternative hypothesis was presented by Canadian anthropologist Peter Frost, who claims blond hair evolved very quickly in a specific area at the end of the last ice age by means of sexual selection.

Blond hair tends to turn darker with age, and many children's blond hair turns light, medium, dark brown or black before or during their adult years.

It gradually eclipsed the native term "fair", of same meaning, from Old English fæġer, causing "fair" later to become a general term for "light complexioned".

This earlier use of "fair" survives in the proper name Fairfax, from Old English fæġer-feahs meaning "blond hair".
