There are advantages and disadvantages to being born ginger. Red hair comes from a recessive gene, which is why it's rare. Both genetic parents have to contribute a red-haired gene for the color to express itself. That same gene gives the offspring a few other things that make him or her different from people with black, brown, or blond hair. For example, did you know that redheads normally don't get gray hair?
The pigment in red hair stays around much longer than other colours, and instead of going grey, the reddish colour simply fades to a silver-white.
A woman I know did exactly that, and I came close to asking where she got her color done. Read the rest of the things that make redheads different at Buzzfeed.
