I have red hair and it actually occurs naturally in 1 to 2 % of the population.  I must admit though mine isn't natural!
Interesting, Red hair is popular to what tribe?
I know that it occurs more frequently in people of northern or western European ancestry and less frequently in other populatios
How about the Indians?
I havent seen anything about that but maybe.  It varies in hues from deep burgundy or bright copper through to burnt orange or red orange and strawberry blondee
