I love red hair, just died mine! Real red hair only occurs naturally in 1–2% of the human population.
That's cool!  What countries do you think have the most naturally red-headed people?
Usually in people of northern or western European ancestry, and less frequently in other populations.
I've noticed that natural redheads usually have freckles. Do you think that is accurate?
Yes! In fact, red heads usually have lighter eye colours and sensitivity to ultraviolet  light!
