Young Dark Blonde Girl With Green Eyes Posing In The Nature

Blond hair is most common in Caucasian infants and children, so much so that the term "baby blond" is often used for very light colored hair. Babies may be born with blond hair even among groups where adults rarely have blond hair, although such natal hair usually falls out quickly. Blond hair tends to turn darker with age, and many children's blond hair turns light, medium, or dark brown or black before or during their adult years.
Culture, folklore, and mythology
An early Greek writer, Xenophanes (6th century BC) described the Thracians as a blond-haired race, although other translations render the Greek phrase in question as "red haired".
