To get a blonde look, you soon may not need to visit a hair clinic or a specialist barber.

A single-letter change in the genetic code is enough to generate blonde hair in humans, fascinating research shows.

In a first, the study outlines how tiny DNA changes can reverberate through our genome in ways that may affect evolution, migration and even human history.

"This particular genetic variation in humans is associated with blonde hair, but it is not associated with eye colour or other pigmentation traits," said David Kingsley from Howard Hughes Medical Institute (HHMI) at Stanford University.

According to Kingsley, a handful of genes likely determine hair colour in humans.
