Why do surfers have blonde hair?

Surfers have blonde (or lighter colored) hair, because the sun bleaches their hair to make it lighter. In addition, the salt water from the ocean affects their hair to make their hair lighter.

Can the Sun give you blonde hair?

Melanin is a pigment found in your skin and hair cells that gives each its color. It does seem weird that the sun bleaches our hair and darkens our skin. The sun bleaches and destroys the melanin in your hair giving you lighter hair. Since hair is dead, the hair will stay that color until new hair comes in.
