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
ed orange and strawberry blondee ,are those a type of red hair?
apparently yes.  it is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin
Is red hair be also related to health issue?
I haven't seen anything about that but it is associated with fair skin, lighter eye color, and sensitivity to ultraviolet light
Wow! So sensitivity to ultraviolet light can cause red hair? How's does that occur?
