I have naturally curly red hair. Only 2% of the population does ! 
Really? It seems much more common than that to me!
Perhaps because people dye their hair ? True red hair has different hues which vary from deep burgundy to a brunt orange or strawberry blonde in appearance
Strawberry blonde is a natural color?! My girlfriend's hair is that color right now, but dyed that way.
The TRUE red hair is characterized by high and low levels of pigmentation
I never knew this much about hair! I thought it was all pretty cut and dry.
One secret ? Red haired peeps generally have fair skin, color, and lighter eyes.. Which is a great clue ! :)
I kinda knew that. And freckles too!
Try traveling with red hair on airline flights ! lol. Some cultures ridicule us, some admire us. 
I bet. Do you think people were ever burned at the stake for being witches for having red hair?
