Red hair occurs naturally in 1–2% of the human population. It occurs more frequently (2–6%) in people of northern or western European ancestry, and less frequently in other populations. Red hair appears most commonly in people with two copies of a recessive allele on chromosome 16 which produces an altered version of the MC1R protein.
Red hair varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin. The term redhead has been in use since at least 1510. It is associated with fair skin color, lighter eye colors (gray, blue, green, and hazel), freckles, and sensitivity to ultraviolet light.
Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered.

Historical
Several accounts by Greek writers mention redheaded people. A fragment by the poet Xenophanes describes the Thracians as blue-eyed and red-haired.
A free-spirited young girl has three middle-aged admirers, each of whom sees her from a completely different perspective. Unknown to her, they also happen to be the guardians of a wealthy young man to whom she is attracted.

What is the origin of red hair and why did it develop in the first place? Now red hair is the rarest hair color in the world, at around 2% of the global population, and it is most common in people of Northern European ancestry, at around 2–6%. It is particularly associated with Celtic countries, with Scotland and Ireland having the highest percentage of people with naturally red hair in the world. Estimates seem to vary for Scotland at between 6-13% of the population, with around 10% of people in Ireland having red hair. Red heads are found in other regions across the globe however, including the Udmurt Republic of Russia, who some say possess the “reddest hair in the world.”
Interestingly, multiple studies have shown that people with red hair perceive pain differently to others. Red heads may be more sensitive to certain types of pain and can require higher doses of some pain-killing medications, and they often need about 20 percent more anesthesia to be sedated. Some studies indicate however that the general pain tolerance of red-heads may be higher. People with red hair also respond more effectively to opioid pain medications, requiring lower doses.
This is pretty wild to think, so why does this seem to be the case? Well it’s to do with the main genetic variant that causes red hair in the first place. To be more specific, red heads have a variant of the melanocortin-1 receptor (MC1R) gene located on chromosome 16, which seems to be the primary driver of red hair, although other studies have pinpointed more genes that also may play a role in whether red hair is expressed or not, but this is still being mapped.

Stepping out of the gray day she came Her red hair falling like the sky Love held them there in that moment With the whole world passing by He could look through all of his books And not find a line that would do To tell of changes she had made in him Just by being there, oh So good just to walk in the light And may the moon shine down on love at every night And sometimes it seems the only things real
This meant all they needed to say when asked about an item and its price was, “Talk to the nice woman with red hair.” ... Some bargained with flare and I appreciated their moxy and usually cut them a deal.
